Abstract
A semiconductor apparatus with MOS transistors for transmitting electrons from an n type source layer to an n type drain layer through a first channel region in an n-channel MOS transistor and transmitting holes from a p type source layer to a p type drain layer through a second channel region in a p-channel MOS transistor consists of a field oxide layer for separating the n-channel MOS transistor from the p-channel MOS transistor, an n type gate electrode mounted on a first gate oxide film arranged on the first channel region, a p type gate electrode mounted on a second gate oxide film arranged on the second channel region and positioned far away from the n type gate electrode to prevent impurities implanted into one of tile gate electrodes from diffusing into the other gate electrode, and a gate metal wiring connecting the gate electrodes through a gate contact hole to miniaturize the transistors.
