Abstract:
A thin sheet (20) disposed on a carrier (10) via a surface modification layer (30) to form an article (2), wherein the article may be subjected to high temperature processing, as in FEOL semiconductor processing, not outgas and have the thin sheet maintained on the carrier without separation therefrom during the processing, yet be separated therefrom upon room temperature peeling force that leaves the thinner one of the thin sheet and carrier intact. Interposers (56) having arrays (50) of vias (60) may be formed on the thin sheet, and devices (66) formed on the interposers. Alternatively, the thin sheet may be a substrate on which semiconductor circuits are formed during FEOL processing.

Also disclosed are a method of making and a method of using the magnetizable glass ceramic composition.
Abstract:
A method for forming a plurality of precision holes in a substrate by drilling, including affixing a sacrificial cover layer to a surface of the substrate, positioning a laser beam in a predetermined location relative to the substrate and corresponding to a desired location of one of the plurality of precision holes, forming a through hole in the sacrificial cover layer by repeatedly pulsing a laser beam at the predetermined location, and pulsing the laser beam into the through hole formed in the sacrificial cover layer. A work piece having precision holes including a substrate having the precision holes formed therein, wherein a longitudinal axis of each precision hole extends in a thickness direction of the substrate, and a sacrificial cover layer detachably affixed to a surface of the substrate, such that the sacrificial cover layer reduces irregularities of the precision holes.
