Abstract:
A semiconductor device comprising:a plurality of shallow trench isolation bands formed in a band-like shape within an element formation region defined by a shallow trench isolation region; a plurality of channels isolated from each other by said shallow trench isolation bands and extending parallel to each other; a common source region or a common source electrode formed at one end of each of said channels; a common drain region or a common drain electrode formed at the other end of each of said channels; a common gate electrode formed on said channels across said shallow trench isolation bands; a first MISFET (Metal Insulator Semiconductor Field Effect Transistor) with said shallow trench isolation bands, channels, a common source region or a common source electrode, a common drain region or a common drain electrode, and a common gate region or a common gate electrode; and a second MISFET with a different number of channels than said first MISFET, wherein said channels of said first and second MISFETs have the same channel width.
