Abstract

A chuck design for coating and transfer of highly uniform adhesive films used in fabricating thermal ink jet devices is disclosed. The chuck 1 is a hollow metal plate comprised of a circumferential groove 2, an evacuatable cavity 3 and vacuum take off port 4 as shown in Figures 1A (side view) and 1B (top view). The chuck may be made by casting or machining a metal disk of appropriate size. The chuck is further machined to achieve highly flat and smooth top and bottom surfaces (Fig. 1A) of less than 1 mil roughness and then spin balanced.
