摘要:
A method of fabricating a dynamic random memory. On a semiconductor substrate comprising a memory cell region and a periphery circuit region, a first field implantation and a first anti-punch through implantation are performed. Using a photo-resist layer formed to cover the memory cell region as a mask, the periphery circuit region is performed with a second field implantation and a second anti-punch through implantation.
