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 surgery time. There are several disadvantages of computer-assisted surgery. A major disadvantage of this system is their cost. With a price tag of a million dollars , their cost is nearly prohibitive. Some people believe that improvements in technology, such as haptics, increased processor speeds, and more complex and capable software will increase the cost of these systems. Another disadvantage is the size of these systems. These systems have relatively large footprints and relatively cumbersome robotic arms. This is an important disadvantage in today's already crowded-operating rooms. It may be difficult for both the surgical team and the robot to fit
