    摘要: A method of fabricating a semiconductor-on-insulator structure from a pair of semiconductor wafers, includes forming an oxide layer on at least a first surface of a first one of the wafers and performing a bonding enhancement implantation step by ion implantation of a first species in the first surface of at least either of the pair of wafers. The method further includes performing a cleavage ion implantation step on one of the pair of wafers by ion implanting a second species to define a cleavage plane across a diameter of the wafer at the predetermined depth below the top surface of the one wafer. The wafers are then bonded together by placing the first surfaces of the pair of wafers onto one another so as to form an semiconductor-on-insulator structure. The method also includes separating the one wafer along the cleavage plane so as to remove a portion of the one wafer between the second surface and the cleavage plane, whereby to form an exposed cleaved surface of a remaining portion of the one wafer on the semiconductor-on-insulator structure. Finally, the cleaved surface is smoothed, preferably by carrying out a low energy high momentum ion implantation step.

    摘要: A plasma immersion ion implantation reactor for ion implanting a species into a surface layer of a workpiece includes an enclosure which has a side wall and a ceiling defining a chamber and a workpiece support pedestal within the chamber having a workpiece support surface facing the ceiling and defining a process region extending generally across the wafer support pedestal and confined laterally by the side wall and axially between the workpiece support pedestal and the ceiling. The enclosure has at least a first pair of openings at generally opposite sides of the process region and a first hollow conduit outside of the chamber having first and second ends connected to respective ones of the first pair of openings, so as to provide a first reentrant path extending through the conduit and across said process region. A gas distribution apparatus is provided on or near an interior surface of the reactor for introducing a process gas containing the species to be ion implanted and a first RE plasma source power applicator for generating a plasma in the chamber.

    摘要: A method of measuring ion dose in a plasma immersion ion implantation reactor during ion implantation of a selected species into a workpiece includes placing the workpiece on a pedestal in the reactor and feeding into the reactor a process gas comprising a species to be implanted into the workpiece, and then coupling RF plasma source power to a plasma in the reactor. It further includes coupling RF bias power to the workpiece by an RF bias power generator that is coupled to the workpiece through a bias feedpoint of the reactor and measuring RF current at the feedpoint to generate a current-related value, and then integrating the current-related over time to produce an ion implantation dose-related value.

    摘要: A valve system having high maximum gas flow rate and fine control of gas flow rate, includes a valve housing for blocking gas flow through a gas flow path, a large area opening through said housing having a first arcuate side wall and a small area opening through said housing having a second arcuate side wall, and respective large area and small area rotatable valve flaps in said large area and small area openings, respectively, and having arcuate edges congruent with said first and second arcuate side walls, respectively and defining therebetween respective first and second valve gaps. The first and second valve gaps are sufficiently small to block flow of a gas on one side of said valve housing up to a predetermined pressure limit, thereby obviating any need for O-rings.
