ABSTRACT:
A contactless channel write/erase flash memory cell structure and its fabricating method for increasing the level of integration is disclosed. The present invention utilizes a buried diffusion method to form an N+-doped region that acts as a drain of the flash memory cell and a P-doped region underneath an oxide layer. The N+-doped region and the P-doped region extend to in a bit line direction and a metal contact is used to connect the two away from any of the N+-doped region and the P-doped region of the flash memory cell for decreasing the numbers of the metal contacts in the flash memory cell and reducing dimensions of the device.
