T-CAD (TCAD) - Technology CAD (Википедия)
Источник: https://en.wikipedia.org/wiki/Technology_CAD

QUOTE
Technology CAD (or Technology Computer Aided Design, or TCAD) is a branch of electronic design automation that models semiconductor fabrication and semiconductor device operation.

The modeling of the fabrication is termed Process TCAD, while the modeling of the device operation is termed Device TCAD. Included are the modelling of process steps (such as diffusion and ion implantation), and modelling of the behavior of the electrical devices based on fundamental physics, such as the doping profiles of the devices. TCAD 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 derive them from the underlying physics. (However, the SPICE simulator itself is usually considered as part of ECAD rather than TCAD.)

Hierarchy of technology CAD tools building from the process level to circuits. Left side icons show typical manufacturing issues; right side icons reflect MOS scaling results based on TCAD (CRC Electronic Design Automation for IC Handbook, Chapter 25)

From the diagram on the right:

    See SPICE for an example of a circuit simulator
    See semiconductor device modeling for a description of modeling devices from dopant profiles.
    See semiconductor process simulation for the generation of these profiles
    See BACPAC for an analysis tool that tries to take all of these into account to estimate system performance

Providers

Current major suppliers of TCAD tools include Synopsys, Silvaco, Crosslight, Cogenda Software|VisualTCAD, Global TCAD Solutions and Tiberlab[11]. The open source GSS,[12] Archimedes,[13] Aeneas,[14] NanoTCAD ViDES, DEVSIM[15], and GENIUS have some of the capabilities of the commercial products.
