摘要:
An electrically programmable device with embedded EEPROM and method for making thereof. The method includes providing a substrate including a first device region and a second device region, growing a first gate oxide layer in the first device region and the second device region, and forming a first diffusion region in the first device region and a second diffusion region and a third diffusion region in the second device region. Additionally, the method includes implanting a first plurality of ions to form a fourth diffusion region in the first device region and a fifth diffusion region in the second device region. The fourth diffusion region overlaps with the first diffusion region.
