Method of manufacturing a glass article to provide increased bonding of metal to a glass substrate via the generation of a metal oxide layer, and glass articles such as glass interposers including the metal oxide layer

Abstract

A method of manufacturing a glass article comprises: (A) forming a first layer of catalyst metal on a glass substrate; (B) heating the glass substrate; (C) forming a second layer of an alloy of a first metal and a second metal on the first layer; (D) heating the glass substrate, thereby forming a glass article comprising: (i) the glass substrate; (ii) an oxide of the first metal covalently bonded thereto; and (iii) a metallic region bonded to the oxide, the metallic region comprising the catalyst, first, and second metals. In embodiments, the method further comprises (E) forming a third layer of a primary metal on the metallic region; and (F) heating the glass article thereby forming the glass article comprising: (i) the oxide of the first metal covalently bonded the glass substrate; and (ii) a new metallic region bonded to the oxide comprising the catalyst, first, second, and primary metals.
