Abstract
Processes for making a membrane having a curved feature are disclosed. A profile-transferring substrate surface having a curved feature is created by vacuum bonding a membrane to a top surface of a substrate, where the top surface has a cavity formed therein. The surface of the membrane is exposed to a fluid pressure such that the membrane deforms and the undersurface of the membrane touches the bottom of the cavity. The curved feature formed in the deformed membrane can be made permanent by annealing the bonding areas between membrane and substrate. A uniform layer of material deposited over the exposed surface of the membrane will include a curved feature at the location where the membrane has bent into the cavity. After at least one layer of material has been uniformed deposited on the membrane, the cavity can be etched open from the bottom to remove the membrane from the underside.
