Abstract:
A method of making metallic features on a support comprising the steps of:(a) providing a resist on said support so as to leave openings in said resist at locations where metallic features are to be formed; (b) depositing a principal metal on said support in said openings to form a principal metal deposit with a top surface remote from the support and edge surfaces extending downwardly from the top surf ace toward the support; (c) treating said resist so as to remove resist immediately adjacent said principal metal and form gaps between said edge surfaces and said resist and thereby expose the edge surfaces of the principal metal deposit while leaving at least some of the resist on regions of the support remote from the principal metal deposit; and (d) depositing a cover metal onto the exposed edge surfaces of the principal metal deposit while said resist remains on said regions of the support remote from the principal metal deposit.
