| 20080293206 | UNIQUE LDMOS PROCESS INTEGRATION - Exemplary embodiments provide manufacturing methods for forming a doped region in a semiconductor. Specifically, the doped region can be formed by multiple ion implantation processes using a patterned photoresist (PR) layer as a mask. The patterned PR layer can be formed using a hard-bakeless photolithography process by removing a hard-bake step to improve the profile of the patterned PR layer. The multiple ion implantation processes can be performed in a sequence of, implanting a first dopant species using a high energy; implanting the first dopant species using a reduced energy and an increased implant angle (e.g., about 90 or higher); and implanting a second dopant species using a reduced energy. In various embodiments, the doped region can be used as a double diffused region for LDMOS transistors. | 11-27-2008 |

| 20090170317 | CMP PROCESS FOR PROCESSING STI ON TWO DISTINCT SILICON PLANES - A method for semiconductor processing is provided wherein a workpiece having an underlying body and a plurality of features extending therefrom, is provided. A first set of the plurality of features extend from the underlying body to a first plane, and a second set of the plurality features extend from the underlying body to a second plane. A protection layer overlies each of the plurality of features and an isolation layer overlies the underlying body and protection layer, wherein the isolation has a non-uniform first oxide density associated therewith. The isolation layer anisotropically etched based on a predetermined pattern, and then isotropically etched, wherein a second oxide density of the isolation layer is substantially uniform across the workpiece. The predetermined pattern is based, at least in part, on a desired oxide density, a location and extension of the plurality of features to the first and second planes. | 07-02-2009 |

| 20080266124 | Domestic water leak automatic detectioin and control - The Domestic Water Leak Automatic Detection and Control is a system to be installed in the home to detect any water leaks from plumbing, appliances and spills. The system is designed for the home owner to be simple and intuitive in nature. No setup or programming is required by the owner. Indicators assure the normal operation of the system. When an abnormal condition occurs, the system controller alerts by both visual and aural means and turns off the main water supply to the home. | 10-30-2008 |
| 20100315245 | DOMESTIC WATER LEAK AND HUMIDITY DETECTION AND CONTROL APPARATUS - A domestic water leak and humidity detection and control apparatus to monitor and detect water leaks and to alert a user by an aural buzzer and by illuminated green, red, or yellow LEDs of an operative state of the apparatus incorporates one or more sensor sets, each sensor set having one or more leak detectors connected to a central controller; the central controller having for each sensor set a respective comparator set and a respective LED set, and the central controller connected to and controlling the aural buzzer and controlling a water valve to control water leaks originating from a domestic water supply by electrically controlling the water valve. | 12-16-2010 |
