Technology CAD Technology CAD 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
Computer Assisted Passenger Prescreening System II The program was then replaced by a similar program called Secure Flight in early 2005 generating the same concerns over privacy and civil liberties. However, due to public concerns, Secure Flight is not due to become fully operational until 2010. CAPPS II grounded innocent Americans due to false positives. One notable example is the grounding of Senator Ted Kennedy in 2004. Computer Assisted Passenger Prescreening System II The Computer Assisted Passenger Prescreening System II (CAPPS II) was a program of the United States Department of Homeland Security (DHS) instituted to increase security at airports by assessing the risk level of
