Abstract:
Wafers processed by methods of plasma etching are disclosed. In one embodiment, a wafer is prepared by a process including positioning the wafer within a chamber of a plasma etcher, generating plasma ions using a radio frequency power source and a plasma source gas, directing the plasma ions toward the wafer using an electric field, focusing the plasma ions using a plasma focusing ring to increase a flux of plasma ions arriving at a surface of the wafer, and etching a plurality of through-wafer vias in the wafer.

Claim (Index 1):
A method to measure electrical characteristics of wafer etching in a plasma etcher, the method comprising:\n clamping a wafer against a feature plate using a clamp having one or more electrical measurement holes; and measuring at least one electrical characteristic of the feature plate after passing plasma ions through the one or more electrical measurement holes of the clamp to impact the feature plate.
