Semiconductor device having MOS transistors which are serially connected via contacts and conduction layer

摘要

A semiconductor device includes a plurality of signal lines which are arranged at a predetermined pitch; first and second MOS transistors which are connected to the signal lines, and also serially connected to each other; and a connection device which functions as a connection node between the serially-connected first and second MOS transistors, and connects a source area of one of the first and second MOS transistors to a drain area of the other of the first and second MOS transistors via contact holes, which are formed through an insulating layer, and a conduction layer connected to the contact holes.
