Abstract:
A method of fabricating an integrated circuit device comprising:providing semiconductor device structures in and on a semiconductor substrate wherein said semiconductor device structures are covered by an insulating layer;depositing and patterning a metal layer overlying said insulating layer to form metal lines wherein there is a gap between two of said metal lines;depositing a passivation layer overlying said metal lines wherein said gap is not filled completely by said passivation layer;coating said passivation layer with a hydrophillic solvent comprising glycerol wherein said hydrophillic solvent completely fills said gap;coating said passivation layer with a photoresist layer and exposing and developing-said photoresist layer to form a photoresist mask;etching away said passivation layer where it is not covered by said photoresist mask over one of said metal lines which forms a bonding pad; andremoving said photoresist mask to complete the fabrication of said integrated circuit device.
