Abstract:
A method of lithographically patterning a metal deposited onto a HgI2 crystal, comprising the steps of:depositing a metal layer onto a HgI2 crystal surface; spinning adhesion promoter onto said metal layer; spinning photoresist onto said adhesion promoter; soft-baking said photoresist to remove moisture; aligning a mask to said photoresist; exposing a portion of said photoresist that is not concealed by said mask to produce exposed photoresist and unexposed photoresist; removing said mask from said photoresist; developing and removing said exposed photoresist; soft-baking said photoresist a second time; etching said metal layer; flood exposing said unexposed photoresist to produce a second exposed photoresist; and developing and removing said second exposed photoresist.
