摘要： Semiconductor processing apparatus is disclosed which provides for movement of a scanning arm 60 of a substrate or wafer holder 180, in at least two generally orthogonal directions (so-called X-Y scanning). Scanning in a first direction is longitudinally through an aperture 55 in a vacuum chamber wall. The arm 60 is reciprocated by one or more linear motors 90A, 90B. The arm 60 is supported relative to a slide 100 using gimballed air bearings so as to provide cantilever support for the arm relative to the slide 100. A compliant feedthrough 130 into the vacuum chamber for the arm 60 then acts as a vacuum seal and guide but does not itself need to provide bearing support. A Faraday 450 is attached to the arm 60 adjacent the substrate holder 180 to allow beam profiling to be carried out both prior to and during implant. The Faraday 450 can instead or additionally be mounted adjacent the rear of the substrate holder or at 90° to it to allow beam profiling to be carried out prior to implant, with the substrate support reversed or horizontal and out of the beam line.

摘要： An implanter provides two-dimensional scanning of a substrate relative to an implant beam so that the beam draws a raster of scan lines on the substrate. The beam current is measured at turnaround points off the substrate and the current value is used to control the subsequent fast scan speed so as to compensate for the effect of any variation in beam current on dose uniformity in the slow scan direction. The scanning may produce a raster of non-intersecting uniformly spaced parallel scan lines and the spacing between the lines is selected to ensure appropriate dose uniformity.

摘要： A method for producing a lamina from a donor body includes implanting the donor body with an ion dosage and heating the donor body to an implant temperature during implanting. The donor body is separably contacted with a susceptor assembly, where the donor body and the susceptor assembly are in direct contact. A lamina is exfoliated from the donor body by applying a thermal profile to the donor body. Implantation and exfoliation conditions may be adjusted in order to maximize the defect-free area of the lamina.

摘要： This invention relates to an ion beam monitoring arrangement for use in an ion implanter where it is desirable to monitor the flux and/or a cross-sectional profile of the ion beam used for implantation. It is often desirable to measure the flux and/or cross-sectional profile of an ion beam in an ion implanter in order to improve control of ion implantation of a semiconductor wafer or similar. The present invention describes adapting the wafer holder to allow such beam profiling to be performed. The substrate holder may be used progressively to occlude the ion beam from a downstream flux monitor or a flux monitor may be located on the wafer holder that is provided with a slit entrance aperture.

摘要： An indirectly heated button cathode for use in the ion source of an ion implanter has a button member formed of a slug piece mounted in a collar piece. The slug piece is thermally insulated from the collar piece to enable it to operate at a higher temperature so that electron emission is enhanced and concentrated over the surface of the slug piece. The slug piece and collar piece can be both of tungsten. Instead the slug piece may be of tantalum to provide a lower thermionic work function. The resultant concentrated plasma in the ion source is effective to enhance the production of higher charge state ions, particularly P+++ for subsequent acceleration for high energy implantation.

摘要： A vacuum bearing structure comprises a combination of a planar gas bearing with a differentially-pumped vacuum seal. The bearing surface and the vacuum seal surfaces are formed of a porous material divided into a first outer region through which bearing gas can percolate to provide support and an inner second region providing the vacuum seal. An exhaust groove separates the two regions so that bearing gas can flow to atmosphere. The resulting structure can operate at a lower fly height to reduce loading on the differentially-pumped vacuum seal. The structure is particularly useful for motion feedthroughs into vacuum processes such as ion implantation.

摘要： A vacuum seal and fluid bearing apparatus for reducing the distortion of the bearing surfaces of a gas bearing is described. The apparatus includes a stator attached around an aperture in a vacuum housing and having a first planar fluid bearing surface. A movable member for closing the vacuum housing aperture having a second fluid bearing surface extending parallel to the first bearing surface is adapted to be supported spaced from the first bearing surface by a bearing fluid. A vacuum seal is provided between the movable member and the stator. In use, a force due to atmospheric pressure acts on the movable member in a direction normal to the bearing surfaces and a movable member includes a pressure relief structure to reduce any bending moment produced in the movable member by the force.
