Process for making a mask used in x-ray photolithography

A method of manufacturing a mask for use in x-ray photolithography includes the steps of coating a set of wafers (20) with boron nitride (22). The tension in the boron nitride is measured by using a capacitive probe (26) to measure bowing in a set of test wafers. The remaining wafers are attached to...
