Webelectrical characteristics. This effect is caused by the shallow trench isolation (STI) compressive effect along the channel direction, and it originates in the STI process.1–3) A transistor will experience higher STI stress when the active length (LA) is small.4) LA is the distance from the gate edge to the STI edge. Shallow trench isolation (STI), also known as box isolation technique, is an integrated circuit feature which prevents electric current leakage between adjacent semiconductor device components. STI is generally used on CMOS process technology nodes of 250 nanometers and smaller.
