Abstract :
An unusual latch-up phenomenon in a microcontroller with a built-in flash memory was detected. The root cause was identified by TCAD simulation and the latch-up mechanism was explained. A novel solution without additional cost was proposed. After applying this solution, the latch-up immunity was dramatically improved.
