There is provided a technology which allows improvements in manufacturing yield and product reliability in a semiconductor device having a triple well structure. A shallow p-type well is formed in a region different from respective regions in a p-type substrate where a deep n-type well, a shallow p-type well, and a shallow n-type well are formed. A p-type diffusion tap formed in the shallow p-type well is wired to a p-type diffusion tap formed in a shallow n-type well in the deep n-type well using an interconnection in a second layer. The respective gate electrodes of an nMIS and a pMIS each formed in the deep n-type well are coupled to the respective drain electrodes of an nMIS and a pMIS each formed in the substrate using an interconnection in a second or higher order layer.

摘要:
A method of manufacturing a semiconductor device which prevents a short circuit between a gate electrode and a diffusion layer region if a contact hole is shifted from its proper position. A material having an etch selectivity to an interlayer insulation film is formed over the gate electrode to serve as a cover against the formation of a contact hole. A material is not formed over an interconnect line which is required to be exposed to a contact hole.

There are provided a method of manufacturing a semiconductor device which achieves a reduction in implantation masks, and such a semiconductor device. By implanting boron into NMOS regions using a resist mask and another resist mask as the implantation masks, p-type impurity regions serving as the halo regions of access transistors and drive transistors are formed. By further implanting phosphorus or arsenic into a PMOS region using another resist mask as the implantation mask, n-type impurity regions serving as the halo regions of load transistors are formed.

摘要:
A structure is adopted for a layout of an SRAM cell which provides a local wiring 3a between a gate 2a and gate 2b and connects an active region 1a and an active region 1b. This eliminates the necessity for providing a contact between the gate 2a and the gate 2b. Therefore, it is possible to reduce the size of a memory cell region C in a short side direction. Furthermore, a structure whereby a left end of a gate 2c is retreated from the gate 2a and a local wiring 3b which connects the active region 1b and gate 2c disposed in a diagonal direction is adopted. This allows the gate 2a to be shifted toward the center of the memory cell region C.
