Abstract:
A Static Random-Access Memory (SRAM) device and its manufacturing method are presented, relating to semiconductor techniques. The SRAM device includes: a substrate; a first semiconductor column for Pull-Up (PU) transistors and a second semiconductor column for Pull-Down (PD) transistors, with both the first and the second semiconductor columns on the substrate; a first separation region, and a gate stack structure. The first separation region is between the first and the second semiconductor columns and comprises a first region and a second region, the gate stack structure comprises a gate dielectric layer comprising a first part and a second part; a P-type work function regulation layer comprising a first area and a second area adjacent to each other; a N-type work function regulation layer comprising a third area and a fourth area adjacent to each other; and a gate on both the P-type and N-type work function regulation layers.

Claim (Index 16):
The method of  claim 10 , wherein providing a substrate structure comprises:\n providing an initial substrate structure, comprising:\n a substrate; \n a first semiconductor column and a second semiconductor column on the substrate and separated from each other; \n a hard mask layer on the first semiconductor column and the second semiconductor column; and \n a first initial separation material layer filling a space between the first semiconductor column and the second semiconductor column, with an upper surface of the first initial separation material layer substantially level with an upper surface of the hard mask layer; \n conducting an etch-back process on the first initial separation material layer so that an upper surface of the remaining first initial separation material layer is lower than upper surfaces of the first semiconductor column and the second semiconductor column; and removing the hard mask layer to form the substrate structure.
