CMOS Image Sensors are essentially complex analog designs that are a combination of an array of transistors and sense/control blocks that have a requirement of extremely high sensitivity. Since extracted CIS designs can get very large they require high accuracy and capacity simulation capabilities. There are a wide variety of PDKs available from various foundries that have CIS processes. Because CISs are typically mounted in some form of 3D packaging, running off a battery, and are often in physically restricted spaces, electromigration, IR drop analysis and especially thermal are extremely important and Silvaco’s suite of analysis tools can ensure the design of reliable devices.
CCD, solar cells, lasers and silicon photonics can be designed using Silvaco’s TCAD suite. Optical simulation including mode solver and laser whispering gallery mode can be used to simulate the interaction between the silicon and the light that is produced or absorbed.
