Plainview, New York
Plainview is a hamlet and census-designated place (CDP) located near the North Shore of Long Island in the town of Oyster Bay in Nassau County, New York, United States. The population of the CDP was 27,100. The Plainview post office has the ZIP code 11803. Plainview and its neighboring hamlet, Old Bethpage, share a school system, library, fire department, and water district. Law enforcement for the communities is provided by the Nassau County Police Department's Second Precinct. History Plainview's origins date to 1648, when Robert Williams, a settler from Wales, bought land in the area. The land was considered desirable for farming because of a small pond named the Moscopas by local Native Americans, meaning "hole of dirt and water". The remainder of the land in the area was purchased by Thomas Powell in 1695 as part of the Bethpage Purchase. The name "Mannatto Hill" had already appeared on the 1695 deed of the Bethpage Purchase, and the settlement came to be called ...

Fan-out Wafer-level Packaging
Fan-out wafer-level packaging (also known as wafer-level fan-out packaging, fan-out WLP, FOWL packaging, FO-WLP, FOWLP, etc.) is an integrated circuit packaging technology, and an enhancement of standard wafer-level packaging (WLP) solutions. In conventional technologies, a wafer is diced first, and then individual dies are packaged; package size is usually considerably larger than the die size. By contrast, in standard WLP flows integrated circuits are packaged while still part of the wafer, and the wafer (with outer layers of packaging already attached) is diced afterwards; the resulting package is practically of the same size as the die itself. However, the advantage of having a small package comes with a downside of limiting the number of external contacts that can be accommodated in the limited package footprint; this may become a significant limitation when complex semiconductor devices requiring a large number of contacts are considered. Fan-out WLP was developed to rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Layer Deposition
Atomic layer deposition (ALD) is a thin-film deposition technique based on the sequential use of a gas-phase chemical process; it is a subclass of chemical vapour deposition. The majority of ALD reactions use two chemicals called precursors (also called "reactants"). These precursors react with the surface of a material one at a time in a sequential, self-limiting, manner. A thin film is slowly deposited through repeated exposure to separate precursors. ALD is a key process in fabricating semiconductor devices, and part of the set of tools for synthesising nanomaterials. Introduction During atomic layer deposition a film is grown on a substrate by exposing its surface to alternate gaseous species (typically referred to as precursors or reactants). In contrast to chemical vapor deposition, the precursors are never present simultaneously in the reactor, but they are inserted as a series of sequential, non-overlapping pulses. In each of these pulses the precursor molecules reac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spin-transfer Torque
Spin-transfer torque (STT) is an effect in which the orientation of a magnetic layer in a magnetic tunnel junction or spin valve can be modified using a spin-polarized current. Charge carriers (such as electrons) have a property known as spin which is a small quantity of angular momentum intrinsic to the carrier. An electric current is generally unpolarized (consisting of 50% spin-up and 50% spin-down electrons); a spin polarized current is one with more electrons of either spin. By passing a current through a thick magnetic layer (usually called the “fixed layer”), one can produce a spin-polarized current. If this spin-polarized current is directed into a second, thinner magnetic layer (the “free layer”), the angular momentum can be transferred to this layer, changing its orientation. This can be used to excite oscillations or even flip the orientation of the magnet. The effects are usually seen only in nanometer scale devices. Spin-transfer torque memory Spin-tr ...

Doping (semiconductor)
In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor. Small numbers of dopant atoms can change the ability of a semiconductor to conduct electricity. When on the order of one dopant atom is added per 100 million atoms, the doping is said to be ''low'' or ''light''. When many more dopant atoms are added, on the order of one per ten thousand atoms, the doping is referred to as ''high'' or ''heavy''. This is often shown as ''n+'' for n-type doping or ''p+'' for p-type doping. (''See the article on semiconductors for a more detailed description of the doping mechanism.'') A semiconductor doped to such high levels that it acts more like a conductor than a semiconductor is referred to as a degenerate semiconductor. A semiconductor can be considered i-type semiconductor if it ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

II-VI Incorporated
Coherent Corp. (formerly II-VI Incorporated) is an American manufacturer of optical materials and semiconductors. As of 2021, the company had 22,961 employees. Their stock is listed at Nasdaq under the ticker symbol COHR. In 2022, II-VI acquired laser manufacturer Coherent, Inc., and adopted its name. History Coherent was founded as II-VI Incorporated in 1971 by Carl Johnson and James Hawkey. The name "II-VI" is a reference to the groups II and VI in the periodic table, since the company started its business by producing cadmium telluride ( cadmium belongs to group II and tellurium belongs to group VI). The company's first products included lenses, windows, and mirrors for CO lasers. The company held its initial public offering in 1987. According to Carl Johnson, the funds raised by the IPO allowed II-VI to expand its zinc selenide manufacturing capacity. In the 1990s, the company began to grow both on its own and through acquisitions. It purchased Litton Systems' silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
