Abstract

A scribing machine adapter plate is configured to receive and couple a hoop assembly to a chuck on a scribing machine. The adapter plate includes an upper surface and an inner annular vacuum groove and an outer annular vacuum groove formed in the upper surface. A third vacuum groove extends radially between, and communicates with, the inner and outer grooves. The outer vacuum groove includes a vacuum inlet hole that extends from the groove through the adapter plate to provide communication between a vacuum channel in the chuck and the vacuum grooves in the plate. The polymer film of the hoop assembly is disposed on the upper surface to seal the vacuum grooves to hold the film in place during scribing of materials placed on the film.
