摘要： In the manufacture of an EPROM or EEPROM semiconductor device that includes a core region and a peripheral region, a nitride layer is formed over the core region and peripheral region, and an oxide layer is formed over the nitride layer. A layer of photoresist is provided over the oxide layer and is patterned to expose a portion of the oxide layer overlying the core region. A wet etch step is undertaken to remove the exposed portion of the oxide layer, using the patterned photoresist as a mask, and leaving exposed a portion of the nitride layer overlying the core region. After removal of the photoresist, the exposed portion of the nitride layer is etched by a wet etch step with hot phosphoric acid, using the pattered oxide layer as a mask.

摘要： Provided are methods for processing semiconductor substrates. The methods involve etching silicon nitride structures using phosphoric acid solutions maintained at low temperatures, such as between about 110° C. and 130° C. These temperatures provide adequate etching rates and do not damage surrounding metal silicide and silicon oxide structures. The etching rates of silicon nitride may be 10 Angstroms per minute and greater. Lower temperatures also allow decreasing concentrations of phosphoric acid in the etching solutions, which in some embodiments may be less than 90 weight percent. As a result, more selective etching of the silicon nitride structures may be achieved. This selectivity may be as high as hundred times relative to the silicide and silicon oxide structures. The surface conductivity of the silicide structures may remain substantially unchanged by this etching process.
摘要翻译：提供了用于处理半导体衬底的方法。该方法包括使用保持在低温（例如约110℃至130℃）之间的磷酸溶液来蚀刻氮化硅结构。这些温度提供足够的蚀刻速率，并且不会损坏周围的金属硅化物和氧化硅结构。氮化硅的蚀刻速率可以为每分钟10埃或更高。较低的温度也允许蚀刻溶液中磷酸的浓度降低，在一些实施方案中磷酸的浓度可以小于90重量％。结果，可以实现对氮化硅结构的更多的选择性蚀刻。相对于硅化物和氧化硅结构，该选择性可高达百倍。通过该蚀刻工艺，硅化物结构的表面电导率可以保持基本不变。

摘要： Combinatorial workflow is provided for evaluating cleaning processes after forming a gate structure of transistor devices, to provide optimized process conditions for gate stack formation, including metal gate stack using high-k dielectrics. NMOS and PMOS transistor devices are combinatorially fabricated on multiple regions of a substrate, with each region exposed to a different cleaning chemical and process. The transistor devices are then characterized, and the data are compared to categorize the potential damages of different cleaning chemicals and processes. Optimized chemicals and processes can be obtained to satisfy desired device requirements.

摘要： Metal gate high-k capacitor structures with lithography patterning are used to extract gate work function using a combinatorial workflow. Oxide terracing, together with high productivity combinatorial process flow for metal deposition can provide optimum high-k gate dielectric and metal gate solutions for high performance logic transistors. The high productivity combinatorial technique can provide an evaluation of effective work function for given high-k dielectric metal gate stacks for PMOS and NMOS transistors, which is critical in identifying and selecting the right materials.

摘要： An all permanent magnet Electron Cyclotron Resonance, large diameter (e.g., 40 cm) plasma source suitable for ion/plasma processing or electric propulsion, is capable of producing uniform ion current densities at its exit plane at very low power (e.g., below 200 W), and is electrodeless to avoid sputtering or contamination issues. Microwave input power is efficiently coupled with an ionizing gas without using a dielectric microwave window and without developing a throat plasma by providing a ferromagnetic cylindrical chamber wall with a conical end narrowing to an axial entrance hole for microwaves supplied on-axis from an open-ended waveguide. Permanent magnet rings are attached inside the wall with alternating polarities against the wall. An entrance magnet ring surrounding the entrance hole has a ferromagnetic pole piece that extends into the chamber from the entrance hole to a continuing second face that extends radially across an inner pole of the entrance magnet ring.

摘要： A MEMS thermal device is made in a smaller size by decreasing the distance that the two cantilevered portions, a spring cantilever and a latch cantilever, of the device must travel. The smaller distance is accomplished by positioning the two contact surfaces of the spring cantilever and the latch cantilever adjacent to each other in the quiescent state of the switch. When the switch is closed, the spring cantilever moves laterally to clear the contact surface of the latch cantilever, and then the latch cantilever moves its contact surface into position. To close the switch, the spring cantilever is allowed to relax and return to nearly its original position, except for the presence of the latch contact surface. When the spring cantilever is allowed to relax, it stays in the closed position because of friction or because of an angled shape of the contact surfaces.
摘要翻译：通过减小装置的两个悬臂部分（弹簧悬臂和闩锁悬臂）必须行进的距离来制造更小尺寸的MEMS热装置。通过在开关的静止状态下将弹簧悬臂和闩锁悬臂的两个接触表面彼此相邻地定位，实现较小的距离。当开关关闭时，弹簧悬臂横向移动以清除闩锁悬臂的接触表面，然后闩锁悬臂将其接触表面移动到位。为了闭合开关，除了存在闩锁接触面之外，弹簧悬臂可以松弛并返回到其初始位置。当弹簧悬臂被允许松弛时，由于摩擦或由于接触表面的成角度，它停留在关闭位置。
