ZMDI
Zentrum Mikroelektronik Dresden (ZMD) was regarded as the heart of East Germany's microelectronics research in the 1980s as well as its most advanced integrated circuit manufacturer. Together with TU Dresden and VEB Spurenmetalle Freiberg, ZMD formed the foundation for Silicon Saxony, a cluster of microelectronics companies that came to include new fabs by Siemens (later Infineon Technologies) and AMD (later GlobalFoundries). 1961: Arbeitsstelle für Molekularelektronik (AME) The company was founded in 1961 in Dresden under the leadership of Werner Hartmann as a research institute with the goal of developing technologies for manufacturing integrated circuits, following the seminal patents by Jack Kilby and Robert Noyce two years earlier. Initially, it was named ''Arbeitsstelle für Molekularelektronik'' (Department of Molecular Electronics) and reported to the government's Office of Nuclear Research and Technology. In 1965 the institute was moved to the combine ''VVB Baueleme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kombinat Mikroelektronik Erfurt
VEB Kombinat Mikroelektronik Erfurt was an important manufacturer of active electronic components in East Germany. It should not be confused with the more well-known VEB Kombinat Robotron Dresden which used integrated circuits from Kombinat Mikroelektronik in its computers. Their products often carried the trademark , but this was used on most electronic products from East Germany from otherwise unrelated companies. History The Kombinat Mikroelektronik Erfurt was formed in 1978 when the ''VVB Bauelemente und Vakuumtechnik'' was split into ''VEB Kombinat Elektronische Bauelemente Teltow'' for passive electronic components and ''VEB Kombinat Mikroelektronik Erfurt'' for active electronic components. However, the history of many of the individual plants reaches back further, in some cases to before the Second World War. In 1971 the first integrated circuits had been manufactured — the D100C ( TTL) by Halbleiterwerk Frankfurt (Oder) and the U101D (PMOS logic) by Funkwerk Erf ...

Dresden
Dresden (; ; Upper Saxon German, Upper Saxon: ''Dräsdn''; , ) is the capital city of the States of Germany, German state of Saxony and its second most populous city after Leipzig. It is the List of cities in Germany by population, 12th most populous city of Germany, the fourth largest by area (after Berlin, Hamburg, and Cologne), and the third-most populous city in the area of former East Germany, after Berlin and Leipzig. Dresden's urban area comprises the towns of Freital, Pirna, Radebeul, Meissen, Coswig, Saxony, Coswig, Radeberg, and Heidenau and has around 790,000 inhabitants. The Dresden metropolitan area has approximately 1.34 million inhabitants. Dresden is the second largest city on the River Elbe after Hamburg. Most of the city's population lives in the Dresden Basin, Elbe Valley, but a large, albeit very sparsely populated, area of the city east of the Elbe lies in the West Lusatian Hill Country and Uplands (the westernmost part of the Sudetes) and thus in Lusatia. ...

Silicon Saxony
Silicon Saxony is a registered industry association of around 600 companies in the microelectronics and related high-tech sectors in Saxony, Germany. Many of those firms are situated in the north of Dresden. The term "Silicon Saxony" originated in a 1998 Time (magazine), ''Time'' magazine article, comparing the former East German state to Silicon Valley. Industrial fields The companies develop and produce computer calculation and memory chips or new materials and electronics for solar companies. The developed and produced small semiconductors chips are used in all kinds of cars, mobile phones, TV sets and so on. History Even before Germany's reunification, Dresden was a major center of microelectronics in the Eastern bloc with 3,500 employees. While mechanical engineering, which has a long history in the south of eastern Germany, suffered after the collapse of the Soviet Union, the microelectronics industry was, with public help from the state, one of the first industrial secto ...

Volkseigener Betrieb
The Publicly Owned Enterprise (; abbreviated VEB) was the main legal form of industrial enterprise in East Germany. These state-owned enterprise were all publicly owned and were formed after mass nationalisation between 1945 and the early 1960s, and the handing back in 1954 of some 33 enterprises previously taken by the Soviet Union The Union of Soviet Socialist Republics.

7400 Series
The 7400 series is a popular logic family of transistor–transistor logic (TTL) integrated circuits (ICs). In 1964, Texas Instruments introduced the SN5400 series of logic chips, in a ceramic semiconductor package. A low-cost plastic package SN7400 series was introduced in 1966 which quickly gained over 50% of the logic chip market, and eventually becoming ''de facto'' standardized electronic components. Since the introduction of the original bipolar-transistor TTL parts, Pin-compatibility, pin-compatible parts were introduced with such features as low power CMOS technology and LVCMOS, lower supply voltages. Surface-mount technology, Surface mount packages exist for several popular logic family functions. Overview The 7400 series contains hundreds of devices that provide everything from basic logic gates, flip-flop (electronics), flip-flops, and counters, to special purpose bus transceivers and arithmetic logic units (ALU). Specific functions are described in a list of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bipolar Junction Transistor
A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor (FET), uses only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current between the remaining two terminals, making the device capable of amplification or switching. BJTs use two p–n junctions between two semiconductor types, n-type and p-type, which are regions in a single crystal of material. The junctions can be made in several different ways, such as changing the doping of the semiconductor material as it is grown, by depositing metal pellets to form alloy junctions, or by such methods as diffusion of n-type and p-type doping substances into the crystal. The superior predictability and performance of junction transistors quickly displaced the original point-contact transistor. Diffused trans ...

NAND Gate
In digital electronics, a NAND (NOT AND) gate is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results. A NAND gate is made using transistors and junction diodes. By De Morgan's laws, a two-input NAND gate's logic may be expressed as \overline \lor \overline = \overline, making a NAND gate equivalent to inverters followed by an OR gate. The NAND gate is significant because any Boolean function can be implemented by using a combination of NAND gates. This property is called "functional completeness". It shares this property with the NOR gate. Digital systems employing certain logic circuits take advantage of NAND's functional completeness. NAND gates with two or more inputs are available as integrated circuits in transistor–transistor logic, CMOS, and other logi ...

Halbleiterwerk Frankfurt (Oder)
Volkseigener Betrieb, VEB Halbleiterwerk Frankfurt (Oder) (abbreviated HFO or HWF) was the largest manufacturer of semiconductor devices in the German Democratic Republic. In 1989, HFO produced 110 million integrated circuits (70% of all integrated circuits produced in the GDR in that year), 9.7 million transistors, and 150 million transistor chips. Despite this, HFO did not rise to prominence like Zentrum Mikroelektronik Dresden (of ''U61000, megabit chip'' fame) or VEB Mikroelektronik "Karl Marx" Erfurt (known for Kombinat Mikroelektronik Erfurt#Microprocessors, its microprocessors). Also unlike Zentrum Mikroelektronik Dresden and VEB Mikroelektronik "Karl Marx" Erfurt, HFO did not survive long after German Reunification. History In January 1958, the production of germanium diodes started in the building of a former vocational school. Halbleiterwerk Frankfurt (Oder) was officially founded on 1 January 1959. In January 1961 new production facilities for germanium alloy-junction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
10 μm Process
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
