Semiconductors
A semiconductor is a material with electrical conductivity between that of a conductor and an insulator. Its conductivity can be modified by adding impurities (" doping") to its crystal structure. When two regions with different doping levels are present in the same crystal, they form a semiconductor junction. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others. Silicon is a critical element for fabricating most electronic circuits. Semiconductor devices can display a range of different useful properties, such as passing current more easily in one ...

Zail Singh
Giani Zail Singh (, born Jarnail Singh; 5 May 1916 – 25 December 1994) was an Indian politician from Punjab who served as the president of India from 1982 to 1987 and chief minister of Punjab. He was the first Sikh to become president. Born in Sandhwan in the princely state of Faridkot, Singh trained to be a granthi and was given the title of giani, meaning a learned man, while training at the Sikh Missionary School in Amritsar. Singh was associated with peasant agitations and the movement seeking a representative government in Faridkot. His political activism in the Praja Mandal, an organisation allied with the Indian National Congress, saw him sentenced to solitary confinement between 1938 and 1943. He led a flag satyagraha and formed a parallel government in Faridkot State which were called off only after the intervention of Jawaharlal Nehru and Vallabhbhai Patel. The stints in jail inspired him to change his name to Zail Singh. After independence, Faridkot was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

8-bit Computing
In computer architecture, 8-bit integers or other data units are those that are 8 bits wide (1 octet). Also, 8-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers or data buses of that size. Memory addresses (and thus address buses) for 8-bit CPUs are generally larger than 8-bit, usually 16-bit. 8-bit microcomputers are microcomputers that use 8-bit microprocessors. The term '8-bit' is also applied to the character sets that could be used on computers with 8-bit bytes, the best known being various forms of extended ASCII, including the ISO/IEC 8859 series of national character sets especially Latin 1 for English and Western European languages. The IBM System/360 introduced byte-addressable memory with 8-bit bytes, as opposed to bit-addressable or decimal digit-addressable or word-addressable memory, although its general-purpose registers were 32 bits wide, and addresses were contained in the lower 2 ...

180 Nm Process
The 180 nm process is a MOSFET (CMOS) semiconductor process technology that was commercialized around the 1998–2000 timeframe by leading semiconductor companies, starting with TSMC and Fujitsu, then followed by Sony, Toshiba, Intel, AMD, Texas Instruments and IBM. History The origin of the 180 nm value is historical, as it reflects a trend of 70% scaling every 2–3 years. The naming is formally determined by the International Technology Roadmap for Semiconductors (ITRS). Some of the first CPUs manufactured with this process include Intel Coppermine family of Pentium III processors. This was the first technology using a gate length shorter than that of light used for contemporary lithography, which had a wavelength of 193 nm. Some more recent microprocessors and microcontrollers (e.g. PIC) are using this technology because it is typically low cost and does not require upgrading of existing equipment.

Semiconductor Fabrication Plant
In the microelectronics industry, a semiconductor fabrication plant, also called a ''fab'' or a ''foundry'', is a factory where integrated circuits (ICs) are manufactured. The ''cleanroom'' is where all fabrication takes place and contains the machinery for integrated circuit production such as steppers and/or scanners for photolithography, etching, cleaning, and doping. All these devices are extremely precise and thus extremely expensive. Prices for pieces of equipment for the processing of 300 mm wafers range to upwards of $4,000,000 each with a few pieces of equipment reaching as high as $340,000,000 (e.g. EUV scanners). A typical fab will have several hundred equipment items. Semiconductor fabrication requires many expensive devices. Estimates put the cost of building a new fab at over one billion U.S. dollars with values as high as $3–4 billion not being uncommon. For example, TSMC invested $9.3 billion in its ''Fab15'' in Taiwan. The same company estimations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wafer Fabrication
Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in a semiconductor device fabrication process. Examples include production of radio frequency ( RF) amplifiers, LEDs, optical computer components, and microprocessors for computers. Wafer fabrication is used to build components with the necessary electrical structures. The main process begins with electrical engineers designing the circuit and defining its functions, and specifying the signals, inputs/outputs and voltages needed. These electrical circuit specifications are entered into electrical circuit design software, such as ''SPICE'', and then imported into circuit layout programs, which are similar to ones used for computer aided design. This is necessary for the layers to be defined for photomask production. The resolution of the circuits increases rapidly with each step in design, as the scale of the circuits at th ...

Integrated Device Manufacturer
An integrated device manufacturer (IDM) is a semiconductor company which designs, manufactures, and sells integrated circuit (IC) products. IDM is often used to refer to a company which handles semiconductor manufacturing in-house, compared to a fabless semiconductor company, which outsources production to a third-party semiconductor fabrication plant. Examples of IDMs are Intel, Samsung, and Texas Instruments, examples of fabless companies are AMD, Nvidia, Qualcomm, and Zhaoxin, and examples of pure play foundries are GlobalFoundries, TSMC, and UMC. Due to the dynamic nature of the semiconductor industry, the term IDM has become less accurate than when it was coined.
