ABSTRACT:
A method of forming a contact structure and a contact structure so formed is described. The structure contacts an underlying layer of a semiconductor junction, wherein the junction comprises the underlying layer of a semiconductor material and is separated from an overlying layer of semiconductor material by creating an undercut region to shade subsequent metal formation. Various steps are performed using inkjet printing techniques.
