45 Nm Process
Per the International Technology Roadmap for Semiconductors, the 45 nm process is a MOSFET technology node referring to the average half-pitch of a memory cell manufactured at around the 2007–2008 time frame. Matsushita and Intel started mass-producing 45 nm chips in late 2007, and AMD started production of 45 nm chips in late 2008, while IBM, Infineon, Samsung, and Chartered Semiconductor have already completed a common 45 nm process platform. At the end of 2008, SMIC was the first China-based semiconductor company to move to 45 nm, having licensed the bulk 45 nm process from IBM. In 2008, TSMC moved on to a 40nm process. Many critical feature sizes are smaller than the wavelength of light used for lithography (i.e., 193 nm and 248 nm). A variety of techniques, such as larger lenses, are used to make sub-wavelength features. Double patterning has also been introduced to assist in shrinking distances between features, especially if dry lit ...

International Technology Roadmap For Semiconductors
The International Technology Roadmap for Semiconductors (ITRS) is a set of documents that was coordinated and organized by Semiconductor Research Corporation and produced by a group of experts in the semiconductor industry. These experts were representative of the sponsoring organisations, including the Semiconductor Industry Associations of Taiwan, South Korea, the United States, Europe, Japan, and China. As of 2017, ITRS is no longer being updated. Its successor is the International Roadmap for Devices and Systems. The documents carried disclaimer: "The ITRS is devised and intended for technology assessment only and is without regard to any commercial considerations pertaining to individual products or equipment". The documents represent best opinion on the directions of research and time-lines up to about 15 years into the future for the following areas of technology: History Constructing an integrated circuit, or any semiconductor device, requires a series of operation ...

Static Random Access Memory
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The ''static'' qualifier differentiates SRAM from ''dynamic'' random-access memory (DRAM): * SRAM will hold its data permanently in the presence of power, while data in DRAM decays in seconds and thus must be periodically refreshed. * SRAM is faster than DRAM but it is more expensive in terms of silicon area and cost. * Typically, SRAM is used for the cache and internal registers of a CPU while DRAM is used for a computer's main memory. History Semiconductor bipolar SRAM was invented in 1963 by Robert Norman at Fairchild Semiconductor. Metal–oxide–semiconductor SRAM (MOS-SRAM) was invented in 1964 by John Schmidt at Fairchild Semiconductor. The first device was a 64-bit MOS p-channel SRAM. SRAM was the main driver behind any new CMOS-based technology fabrica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Nehalem (microarchitecture)
Nehalem is the codename for Intel's 45 nm microarchitecture released in November 2008. It was used in the first generation of the Intel Core i5 and i7 processors, and succeeds the older Core microarchitecture used on Core 2 processors. The term "Nehalem" comes from the Nehalem River. Nehalem is built on the 45 nm process, is able to run at higher clock speeds without sacrificing efficiency, and is more energy-efficient than Penryn microprocessors. Hyper-threading is reintroduced, along with a reduction in L2 cache size, as well as an enlarged L3 cache that is shared among all cores. Nehalem is an architecture that differs radically from NetBurst, while retaining some of the latter's minor features. Nehalem later received a die-shrink to 32 nm with Westmere, and was fully succeeded by "second-generation" Sandy Bridge in January 2011. Technology * Cache line block on L2/L3 cache was reduced from 128 bytes in NetBurst & Merom/Penryn to 64 bytes per line in this gene ...

Intel Developer Forum
The Intel Developer Forum (IDF) was a biannual gathering of technologists to discuss Intel products and products based on Intel products. The first IDF was held in 1997. To emphasize the importance of China, the Spring 2007 IDF was held in Beijing instead of San Francisco, and San Francisco and Taipei shared the Fall IDF event in September and October, respectively. Three IDF shows were scheduled in 2008; with the date of IDF San Francisco notably moving to August rather than September. In previous years, events were held in major cities around the world such as San Francisco, Mumbai, Bangalore, Moscow, Cairo, São Paulo, Amsterdam, Munich and Tokyo. On April 17, 2017, Intel announced that it would no longer be hosting IDF. As a result of this announcement, IDF17, which was scheduled for August in San Francisco, was canceled. 2007 events * April 17–18, 2007 – Beijing, China * September 18–20, 2007 – San Francisco, United States * October 15–16, 2007 – Taipei, Taiwan ...

Xeon
Xeon (; ) is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for error correction code (ECC) memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture (MCA). They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Ultra Path Interconnect (UPI) bus, which replaced ...

System-on-a-chip
A system on a chip (SoC) is an integrated circuit that combines most or all key components of a computer or electronic system onto a single microchip. Typically, an SoC includes a central processing unit (CPU) with memory, input/output, and data storage control functions, along with optional features like a graphics processing unit (GPU), Wi-Fi connectivity, and radio frequency processing. This high level of integration minimizes the need for separate, discrete components, thereby enhancing power efficiency and simplifying device design. High-performance SoCs are often paired with dedicated memory, such as LPDDR, and flash storage chips, such as eUFS or eMMC, which may be stacked directly on top of the SoC in a package-on-package (PoP) configuration or placed nearby on the motherboard. Some SoCs also operate alongside specialized chips, such as cellular modems. Fundamentally, SoCs integrate one or more processor cores with critical peripherals. This comprehensive integrat ...

14 Nm Process
The "14 nanometer process" refers to a marketing term for the MOSFET technology node that is the successor to the "22nm" (or "20nm") node. The "14nm" was so named by the International Technology Roadmap for Semiconductors (ITRS). Until about 2011, the node following "22nm" was expected to be "16nm". All "14nm" nodes use FinFET (fin field-effect transistor) technology, a type of multi-gate MOSFET technology that is a non-planar evolution of planar silicon CMOS technology. Since at least 1997, "process nodes" have been named purely on a marketing basis, and have no relation to the dimensions on the integrated circuit; neither gate length, metal pitch or gate pitch on a "14nm" device is fourteen nanometers. For example, TSMC and Samsung's "10 nm" processes are somewhere between Intel's "14 nm" and "10 nm" processes in transistor density, and TSMC's " 7 nm" processes are dimensionally similar to Intel's "10 nm" process. Samsung Electronics taped out a "14 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
22 Nm Process
The "22 nm" node is the process step following 32 nm in CMOS MOSFET semiconductor device fabrication. It was first demonstrated by semiconductor companies for use in RAM in 2008. In 2010, Toshiba began shipping 24 nm flash memory chips, and Samsung Electronics began mass-producing 20 nm flash memory chips. The first consumer-level CPU deliveries using a 22 nm process started in April 2012 with the Intel Ivy Bridge processors. Since at least 1997, "process nodes" have been named purely on a marketing basis, and have no relation to the dimensions on the integrated circuit; neither gate length, metal pitch or gate pitch on a "22nm" device is twenty-two nanometers. The ITRS 2006 Front End Process Update indicates that equivalent physical oxide thickness will not scale below 0.5 nm (about twice the diameter of a silicon atom), which is the expected value at the 22 nm node. This is an indication that CMOS scaling in this area has reached a wall at this p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
32 Nm Process
The "32 nm" node is the step following the "45 nm" process in CMOS (MOSFET) semiconductor device fabrication. "32-nanometre" refers to the average half-pitch (i.e., half the distance between identical features) of a memory cell at this technology level. Toshiba produced commercial 32 GiB NAND flash memory chips with the "32nm" process in 2009. Intel and AMD produced commercial microchips using the "32 nm" process in the early 2010s. IBM and the Common Platform also developed a "32 nm" high-κ metal gate process. Intel began selling its first "32 nm" processors using the Westmere architecture on 7 January 2010. Since at least 1997, "process nodes" have been named purely on a marketing basis, and have no relation to the dimensions on the integrated circuit; neither gate length, nor metal pitch, nor gate pitch on a "32nm" device is thirty-two nanometers. The "28 nm" node is an intermediate half-node die shrink based on the "32 nm" process. The "32 nm" process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Low-κ Dielectric
In semiconductor manufacturing, a low-κ is a material with a small relative dielectric constant (κ, kappa) relative to silicon dioxide. Low-κ dielectric material implementation is one of several strategies used to allow continued scaling of microelectronic devices, colloquially referred to as extending Moore's law. In digital circuits, insulating dielectrics separate the conducting parts (wire interconnects and transistors) from one another. As components have scaled and transistors have gotten closer together, the insulating dielectrics have thinned to the point where charge build up and crosstalk adversely affect the performance of the device. Replacing the silicon dioxide with a low-κ dielectric of the same thickness reduces parasitic capacitance, enabling faster switching speeds (in case of synchronous circuits) and lower heat dissipation. In conversation such materials may be referred to as "low-k" (spoken "low-kay") rather than "low-κ" (low-kappa). Low-κ materials ...
