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
For several years, the Semiconductor Industry Association (SIA) gave this responsibility of coordination to the United States, which led to the creation of an American style roadmap, the National Technology Roadmap for Semiconductors (NTRS). [5] The first semiconductor roadmap, published by the SIA in 1993.
Substrate mapping (or wafer mapping) is a process in which the performance of semiconductor devices on a substrate is represented by a map showing the performance as a colour-coded grid. The map is a convenient representation of the variation in performance across the substrate, since the distribution of those variations may be a clue as to ...
[note 3] Mesh analysis can only be applied if it is possible to map the graph onto a plane or a sphere without any of the branches crossing over. Such graphs are called planar graphs. Ability to map onto a plane or a sphere are equivalent conditions. Any finite graph mapped onto a plane can be shrunk until it will map onto a small region of a ...
Semiconductor fabrication techniques continued to improve throughout. The Micralign, which had "created the modern IC industry", was obsolete by the early 1980s. They were replaced by the new steppers , which used high magnifications and extremely powerful light sources to allow a large mask to be copied onto the wafer at ever-smaller sizes.
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 ...
Cover of the comic book "THE SHMOO" The plot takes its name from the Shmoo, a fictional species created by Al Capp in the cartoon Li'l Abner.These small, blob-like creatures have shapes similar to the "working" volumes that would be enclosed by shmoo plots drawn against three independent variables (such as voltage, temperature, and response speed).
