| 20120034729 | MANUFACTURING METHOD FOR LIGHT-SENSING STRUCTURE - A manufacturing method for manufacturing a light-sensing structure is provided. The manufacturing method includes the steps as follows. (a) A circuit layer is formed on an upper surface of a first substrate, wherein the first substrate includes at least one light-sensing device and the circuit layer includes at least one device structure and at least one release feature that is made of metal and is formed on part of the light-sensing device and the device structure. (b) A first light-filtering layer is formed on part of the circuit layer. (c) The release feature is removed by a wet-etching process. | 02-09-2012 |
| 20110250760 | METHOD FOR MANUFACTURING A MICRO-ELECTROMECHANICAL STRUCTURE - Disclosed herein is a method for manufacturing a micro-electromechanical structure. The method includes the following steps. A circuitry layer having a release feature is formed on an upper surface of a first substrate. A passive layer is formed on the circuitry layer without covering the release feature. The release feature is removed to expose the first substrate by a wet etching process. A portion of the exposed first substrate is anisotropically etched. A second substrate is disposed above the circuitry layer. A cavity is formed in the lower surface of the first substrate. The cavity is filled with a polymeric material. A portion of the first substrate under the microstructure is removed to release the micro-electromechanical structure. | 10-13-2011 |
| 20110248723 | CAPACITIVE SENSOR HAVING CALIBRATION MECHANISM AND CAPACITIVE SENSING METHOD - A capacitive sensor with a calibration mechanism is provided. The capacitive sensor includes a set of sensing capacitors to generate a capacitance variation, a subtraction circuit and an integration circuit. The subtraction circuit includes a first capacitor array to generate offset-adjusting charges and a second capacitor array to generate subtraction charges according to an initial offset and a sensitivity of the sensing capacitors respectively. The integration circuit includes two input ends, wherein one of them is connected to the sensing capacitors and the subtraction circuit. During a sensing period, the integration circuit performs integration according to the capacitance variation and performs cancellation of the effect of the initial offset according to the offset-adjusting charges to generate an integration output signal that is continuously subtracted by the subtraction charges during a computing period to generate a subtraction count. A capacitive sensing method is disclosed herein as well. | 10-13-2011 |
