Patent ID: 8741747

Claim:
A method for processing a glass substrate, comprising: providing a glass substrate including a first surface, a second surface, and a side surface between the first surface and the second surface; forming an opaque conductive layer material surrounding the first surface, the second surface, and the side surface of the glass substrate; removing a first portion of the opaque conductive layer material from the first surface of the glass substrate and from a first part of the side surface close to first surface, such that a second portion of the opaque conductive layer material remaining on the second surface and on the part of the side surface close to the second surface of glass substrate forms an opaque conductive layer, wherein the opaque conductive layer is made of a semiconductor material comprising a poly Si or a doped poly Si and the opaque conductive layer enables the glass substrate to be held by a chuck including an electrical chuck and to be sensed by a sensor including an optical sensor using a semiconductor tool including a transport mechanism; performing a semiconductor process on the first surface of the glass substrate including the opaque conductive layer on the second surface and the part of the side surface close to the second surface, wherein the semiconductor process includes a lithographic process, a thin film process, a diffusion process, or a combination thereof, and is conducted using a semiconductor tool including a transport mechanism; and removing the opaque conductive layer on the second surface and the part of the side surface close to the second surface after the semiconductor process is performed on the first surface of the glass substrate.
