摘要： A multi-layer semiconductor device utilizes the good thermal and electrical properties of a polycrystalline substrate with the electrical properties of single crystal film transferred via wafer bonding. The device structure includes a polycrystalline, e.g., silicon carbide substrate, which was polished. A planarization layer of silicon is formed on the surface, followed by chemical mechanical polishing. The substrate is then bonded to either a bulk silicon wafer or a silicon-on-insulator (SOI) wafer. The silicon (SOI) wafer is thinned to the desired thickness.

摘要： First and second semiconductor wafers are bonded together, with at least one of the wafers having a first layer of silicon, an intermediate oxide layer and a second layer of silicon. The first silicon layer is initially mechanically reduced by around 80% to 90% of its thickness. The remaining silicon layer is further reduced by a plasma etch which may leave an uneven thickness. With appropriate masking the uneven thickness is made even by a second plasma etch. Remaining silicon is removed by a dry etch with XeF2 or BrF3 to expose the intermediate oxide layer. Prior to bonding the semiconductor wafers may be provided with various semiconductor devices to which electrical connections are made through conducting vias formed through the exposed intermediate oxide layer.

摘要： High-speed silicon CMOS circuits and high-power AlGaN/GaN amplifiers are integrated on the same wafer. A thin layer of high resistivity silicon is bonded on a substrate. Following the bonding, an AlGaN/GaN structure is grown over the bonded silicon layer. A silicon nitride or a silicon oxide layer is then deposited over the AlGaN/GaN structure. Following this, a thin layer of silicon is bonded to the silicon nitride/silicon oxide layer. An area for the fabrication of AlGaN/GaN devices is defined, and the silicon is etched away from those areas. Following this, CMOS devices are fabricated on the silicon layer and AlGaN/GaN devices fabricated on the AlGaN/GaN surface.

摘要： Method and apparatus for an improved camlock fitting having outer/inner cam lever which are restrained against unintended opening or rotation by a pivoting locking member which is pivotally mounted onto an axle disposed in a corresponding hole on the cam levers so that the pivoting locking member can be easily pivoted in the vertical plane relative to the cam arms. Each of the outer and inner arms has a pivoting locking member mounted on its underside in a protective housing. The camlock fitting may also have an air vent. Together this provides a safety lock assembly for the cam lock fitting so that when the cam lock fitting is pressurized unbeknownst to the operator and the operator attempts to open the cam lock fitting, the safety lock assembly will prevent operation or complete separation of the male and the female portions of the fitting to prevent inadvertent pressurized discharge of hazardous materials.

摘要： A method and apparatus for an improved rotatable safety cam lock fitting having ergonomically designed double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on the inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space therein between. Various configurations of the cam portions relative to each other are provided. Various lever locking assemblies may be used to prevent the cam levers from being inadvertently opened.

摘要： A cam lock fitting having a rotating female portion which may include a safety lock which prevents separation of the male and the female portions of the fitting to prevent inadvertent pressurized discharges. Rotation of the female portion is accomplished by placing a connecting collar on the rear of the female end portion so that the female portion rotates about the connecting collar. The safety lock mechanism operates by placing opposing notches in the end of the male portion so that when the cam levers are opened the male and female portions of the cam lock fitting initially only slightly separate allowing the operator to quickly reclose the cam lock fitting if it contains pressurized material. The rotating female portion easily aligns the cam lobes of the cam lever with the notches on the male coupling so that the male and female portions can be separated.
