Abstract:
1. A method of back metallizing and reinforcing a glass substrate, said method comprising: a. creating a plurality of through-holes in the glass substrate; b. filling the through-holes with a conductive type material; c. applying a plurality of backside metallized pads to a bottom surface of the glass substrate; d. enclosing the backside metallized pads with an under-bump metallization (UBM) pad and e. attaching a sacrificial substrate to the glass substrate, said sacrificial substrate comprising: wherein the adhesive binds the sacrificial layer to the bottom surface the glass substrate, whereby the sacrificial substrate protects the backside metallized pads and UBM pads, whereby the sacrificial substrate reinforces the glass substrate to provide support during handling and processing of the glass substrate.
