Abstract:
A method of manufacturing a static random access memory cell, the method comprising:providing a silicon substrate; defining first and second inverters on the substrate, the first and second inverters respectively each including a first conductivity type of transistor having a respective gate, drain and source, defining first and second inverters, the defining including forming an active area common to the drains of the first conductivity type transistors by doping a contiguous region in the substrate extending from the drain of one of the first conductivity type transistors to the drain of the other first conductivity type transistor and a field oxide formed in the surface, surrounding and isolating the contiguous region; and defining an isolation gate relative to the common active area, between the drains of the first conductivity type transistors, by forming polysilicon on the common active area.
