Abstract
A method for creating a solderable metal layer on a ceramic, glass, or glass ceramic member is described. The described method deposits an aluminum containing mixture on the member by ion vapor deposition creating a metalized ceramic member. A photoresist is applied to the metalized ceramic member. A photomask is applied to the photoresist and the photoresist is exposed to light. After the photomask and exposed photoresist are stripped off, the underlying aluminum containing mixture is removed with an etchant. The remaining photoresist is removed and a metal corrosion inhibiting layer is deposited on the remaining aluminum containing mixture. A solderable layer is then deposited on the metal corrosion inhibiting layer.
