Abstract
The present invention relates generally to a new apparatus and method for screening using electrostatic adhesion. More particularly, the invention encompasses an apparatus that uses an electrostatic charge during the screening process for a semiconductor substrate. Basically, a backing layer is adhered to a green ceramic sheet using an electrostatic charge, while the green ceramic sheet is processed.
