METHOD OF FORMING CONTACTS

摘要

A method of forming a contact is disclosed. A substrate having a desired electrical contact location is provided. The substrate has a conductive layer. A first mask with an edge over the desired electrical contact location is formed on the substrate. A contact material is deposited over the first mask and the substrate. A first portion of the contact material is then removed such that a second portion of the contact material remains to form a contact adjacent to the edge of the mask, over the desired electrical contact location.
