DEFINITION

Classification: 438/621

Contacting diversely doped semiconductive regions (e.g., p-type and n-type regions, etc.):

(under subclass 618) Processes wherein at least one electrical contact is formed to a semiconductive region which is diversely doped (more heavily doped, oppositely doped, etc.) with respect to the semiconductive region contacted by another electrical contact.
