A novel configuration for MOS devices employed in a partially generic gate array type chip having large numbers of generally MOS devices. The MOS devices have a non-rectangular configuration and include at least a first and second region of conductivity type differing from the conductivity type...http://www.google.com.au/patents/US5796130?utm_source=gb-gplus-sharePatent US5796130 - Non-rectangular MOS device configurations for gate array type integrated circuits
