Semiconductor device modeling creates models for the behavior of semiconductor devices based on fundamental physics, such as the doping profiles of the devices. It may also include the creation of compact models (such as the well known SPICE transistor models), which try to capture the electrical behavior of such devices but do not generally ...
[12] [13] The invention of the MOSFET enabled the practical use of metal–oxide–semiconductor (MOS) transistors as memory cell storage elements, a function previously served by magnetic cores. [14] The first modern memory cells were introduced in 1964, when John Schmidt designed the first 64-bit p-channel MOS static random-access memory (SRAM).
Transistor models are used for almost all modern electronic design work. Analog circuit simulators such as SPICE use models to predict the behavior of a design. Most design work is related to integrated circuit designs which have a very large tooling cost, primarily for the photomasks used to create the devices, and there is a large economic incentive to get the design working without any ...
The advent of the metal–oxide–semiconductor field-effect transistor (MOSFET), [12] invented by Mohamed M. Atalla and Dawon Kahng at Bell Labs in 1959, [13] enabled the practical use of metal–oxide–semiconductor (MOS) transistors as memory cell storage elements, a function previously served by magnetic cores in computer memory.

Technology files and design rules are essential building blocks of the integrated circuit design process. Their accuracy and robustness over process technology, its variability and the operating conditions of the IC—environmental, parasitic interactions and testing, including adverse conditions such as electro-static discharge—are critical in determining performance, yield and reliability.
BSIM (Berkeley Short-channel IGFET Model) [1] refers to a family of MOSFET transistor models for integrated circuit design. It also refers to the BSIM group located in the Department of Electrical Engineering and Computer Sciences (EECS) at the University of California, Berkeley, that develops these models.
Also, some of those steps require very high temperatures and must take place after the logic transistors are formed, possibly damaging them. 1T-SRAM is also available in device (IC) form. The GameCube was the first video game system to use 1T-SRAM as main memory storage; the GameCube possesses several dedicated 1T-SRAM devices. 1T-SRAM is also ...
Launched in October 1985, the T414 employed the equivalent of 900,000 transistors and was fabricated with a 1.5 micrometre feature size. It was a 32-bit design, able to process 32-bit units of data and to address up to 4 GB of main memory. [13]
