摘要:
An integrated circuit (100) of CMOS type comprises first (10) and second (20) circuit parts arranged close to one another in a single semiconducting substrate. The circuit combines using a deep doping well (2) for reducing digital noise and implementing a sleep mode for reducing power consumption. Such circuit may contain a random access memory and be a radio communication system-on-chip device. It may advantageously be used within a mobile communication apparatus such as a mobile phone.

A static random-access memory (SRAM) circuit includes at least one access device on a first N-type fin (222) including source and drain sections for a pass region, at least one pull-up device on a P-type fin (226), and at least one pull-down device on a second N-type fin (222) including source-and-drain sections for a pull-down region. The SRAM circuit further comprises epitaxial structures (230, 236) on the source and drain sections of the pass and the pull-down devices, wherein the volume of the epitaxial structures on the source section and the drain section of the pass device (230) differs from the volume of the epitaxial structures on the source and drain section of the pull-down device (236) such that the external resistivity (Rext) for the pull-down region is lower than Rext for the pass region.

A semiconductor device includes a first MISFET and a second MISFET which are formed over a semiconductor substrate and have the same conductive type. The first MISFET has a first gate insulating film arranged over the semiconductor substrate, a first gate electrode arranged over the first gate insulating film, and a first source region and a first drain region. The second MISFET has a second gate insulating film arranged over the semiconductor substrate, a second gate electrode arranged over the second gate insulating film, and a second source region and a second drain region. The first and the second gate electrode are electrically coupled, the first and the second source region are electrically coupled, and the first and the second drain region are electrically coupled. Accordingly, the first and the second MISFET are coupled in parallel. In addition, threshold voltages are different between the first and the second MISFET.
