摘要： An inspection apparatus (40) for in-situ leak testing of the bell seal (30) of a steam turbine (10). The apparatus includes a pair of inflatable bladders (48,52) for defining a sealed volume having the bell seal (30) as its only leakage path. The mass flow rate of pressurized air (70) at various pressures through the bell seal (30) is compared to the known flow rates through a similarly designed bell seal having various degrees of degradation. A camera (60) rotated by motor (62) between the bladders (48,52) provides an indication of the proper positioning of the inspection apparatus (40) and facilitates a visual inspection of the bell seal (30) and retaining nut (42). The inspection apparatus (40) may be inserted into an inlet to the turbine through a disassembled flow control valve without the need for any disassembly of the turbine.

摘要： Semiconductor processing methods of forming conductive projections and methods of increasing alignment tolerances are described. In one implementation, a conductive projection is formed over a substrate surface area and includes an upper surface and a side surface joined therewith to define a corner region. The corner region of the conductive projection is subsequently beveled to increase an alignment tolerance relative thereto. In another implementation, a conductive plug is formed over a substrate node location between a pair of conductive lines and has an uppermost surface. Material of the conductive plug is unevenly removed to define a second uppermost surface, at least a, portion of which is disposed elevationally higher than a conductive line. In one aspect, conductive plug material can be removed by facet etching the conductive plug. In another aspect, conductive plug material is unevenly doped with dopant, and conductive plug material containing greater concentrations of dopant is etched at a greater rate than plug material containing lower concentrations of dopant.

摘要： Some embodiments include methods of forming vertical transistors. A construction may have a plurality of spaced apart fins extending upwardly from a semiconductor substrate. Each of the fins may have vertical transistor pillars, and each of the vertical transistor pillars may have a bottom source/drain region location, a channel region location over the bottom source/drain region location, and a top source/drain region location over the channel region location. Electrically conductive gate material may be formed along the fins while using oxide within spaces along the bottoms of the fins to offset the electrically conductive gate material to be above the bottom source/drain region locations of the vertical transistor pillars. The oxide may be an oxide which etches at a rate of at least about 100 Å/minute with dilute HF at room temperature. In some embodiments the oxide may be removed after the electrically conductive gate material is formed.
