Abstract

A processing method is described which leads to very dense one-device FET memory cells having the following main features: Polysilicon-gate FET with conventional micron/submicron deep source diffusion on one side of the gate and several microns deep drain diffusion on the other side of the gate. Source and drain are self-aligned with respect to the gate, the deep drain having alignment-independent dimensions at the same time.
