20120248063 | FORMING A MEMBRANE HAVING CURVED FEATURES - 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. | 10-04-2012 |
20120252221 | FORMING CURVED FEATURES USING A SHADOW MASK - Processes for making a profile-transferring substrate surface and membranes having curved features are disclosed. A profile-transferring substrate surface having a curved feature is created by isotropic plasma etching through a shadow mask. The shadow mask has a through hole which has a lower portion adjacent to the bottom surface of the shadow mask and an upper portion that is above and narrower than the lower portion. The isotropic plasma etching through the shadow mask can create a curved dent in a planar substrate in a central portion of an area enclosed by the bottom opening. After the shadow mask is removed. A uniform layer of material deposited over the exposed surface of the substrate will include a curved feature at the location of the curved dent in the substrate surface. | 10-04-2012 |
20120262029 | FORMING A MEMBRANE HAVING CURVED FEATURES - Processes for making a membrane having a curved feature are disclosed. Recesses each in the shape of a reversed, truncated pyramid are formed in a planar substrate surface by KOH etching through a mask. An oxide layer is formed over the substrate surface. The oxide layer can be stripped leaving rounded corners between different facets of the recesses in the substrate surface, and the substrate surface can be used as a profile-transferring substrate surface for making a membrane having concave curved features. Alternatively, a handle layer is attached to the oxide layer and the substrate is removed until the backside of the oxide layer becomes exposed. The exposed backside of the oxide layer includes curved portions protruding away from the handle layer, and can provide a profile-transferring substrate surface for making a membrane having convex curved features. | 10-18-2012 |
20130210175 | Forming a Device Having a Curved Piezoelectric Membrane - Processes for forming an actuator having a curved piezoelectric membrane are disclosed. The processes utilize a profile-transferring substrate having a curved surface surrounded by a planar surface to form the curved piezoelectric membrane. The piezoelectric material used for the piezoelectric actuator is deposited on at least the curved surface of the profile-transferring substrate before the profile-transferring substrate is removed from the underside of the curved piezoelectric membrane. The resulting curved piezoelectric membrane includes grain structures that are columnar and aligned, and all or substantially all of the columnar grains are locally perpendicular to the curved surface of the piezoelectric membrane. | 08-15-2013 |
