Method for fabricating a high bias metal oxide semiconductor device
摘要:
A method for fabricating a high bias metal oxide semiconductor device includes using a trench structure instead of the conventional field oxide layer, constructing a structure with a vertical voltage gradient and performing punch implantation and threshold voltage implantation under a doped N.sup.- region and a doped P.sup.- region to increase the channel length.
