For power semiconductor devices (such as BJT, MOSFET, thyristor or IGBT), the safe operating area (SOA) is defined as the voltage and current conditions over which the device can be expected to operate without self-damage. [1] Illustration of safe operating area of a bipolar power transistor.
Listed are many semiconductor scale examples for various metal–oxide–semiconductor field-effect transistor (MOSFET, or MOS transistor) semiconductor manufacturing process nodes. Timeline of MOSFET demonstrations
The need for such programs was recognized relatively early in the history of ICs, and programs to perform this comparison were written as early as 1975. [1] These early programs operated mainly on the level of graph isomorphism, checking whether the schematic and layout were indeed identical. With the advent of digital logic, this was too ...
Reliability engineers are tasked with verifying the adequate stress duration. For example, for an activation energy of 0.7 eV, a stress temperature of 125 °C and a use temperature of 55 °C, an expected operational life of five years is represented by a 557-hour HTOL experiment.
Mask data preparation (MDP), also known as layout post processing, is the procedure of translating a file containing the intended set of polygons from an integrated circuit layout into set of instructions that a photomask writer can use to generate a physical mask.
For example, when testing semiconductor memory: voltages, temperature, and refresh rates can be varied over specified ranges and only certain combinations of these factors will allow the device to operate. Plotted on independent axes (voltage, temperature, refresh rates), the range of working values will enclose a three-dimensional, usually ...
Examples of the latter are a seal ring and filler structures. [13] Producing a reticle layout with test patterns and alignment marks. Layout-to-mask preparation that enhances layout data with graphics operations, such as resolution enhancement techniques (RET) – methods for increasing the quality of the final photomask.
An SOI MOSFET is a metal–oxide–semiconductor field-effect transistor (MOSFET) device in which a semiconductor layer such as silicon or germanium is formed on an insulator layer which may be a buried oxide (BOX) layer formed in a semiconductor substrate. [8] [9] [10] SOI MOSFET devices are adapted for use by the computer industry.
