摘要： The thickness of a semiconductor wafer layer, extending from a mirror-finished surface thereof to a solid-state image sensing device, is measured. Based on the residual thickness data, plasma etching is performed from the mirror-finished surface until a predetermined thickness is reached by controlling the plasma etching amount. By doing this, it is possible to reduce variation in the thickness of the solid-state image sensing device at low cost without causing an increase in the number of processes.

摘要： A method for manufacturing an SOI substrate includes steps of forming a first oxide film on a surface of a first silicon substrate; implanting hydrogen ions into the surface of the first silicon substrate on which the first oxide film is formed to form an ion implant region inside the first silicon substrate; removing the entire or the portion of first oxide film; forming a laminate by bonding the second silicon substrate to a hydrogen ion-implanted surface of the first silicon substrate with the first oxide film, or second oxide film formed on a surface of the second silicon substrate, or the first oxide film and second oxide film, interposed therebetween; and subjecting the laminate to a heat treatment at a predetermined temperature to separate the first silicon substrate along the ion implant region, thereby obtaining an SOI substrate including a thin SOI layer formed on the second silicon substrate with the oxide film interposed therebetween. The method can reduce a degree of contamination from heavy metals inside the SOI substrate.

摘要： A bonded SOI substrate having an active layer which is free from crystal defects is obtained by adding more than 9×1018 atoms/cm3 of boron to a wafer for active layer (10). Since the boron concentration in the wafer for active layer is high, a silicon oxide film is formed at a high rate. Consequently, there can be obtained a Smart-Cut wafer with high throughput. Furthermore, damages to the active layer due to the ion implantation can be reduced, thereby improving the quality of the active layer.

摘要： The bonding surfaces of an active layer wafer and a supporting wafer have fitting surfaces each comprising a part of a spherical surface of the same curvature, and they are to be bonded together with their bonding surfaces superposed with each other. As a result, an area left as not-bonded in the outer peripheral portion of the bonded wafer is reduced and thus a fixed quality area can be expanded. Therefore, the yield of the bonded SOI wafer becomes high, and the chipping, wafer peel-off and the like phenomenon in the subsequent steps of wafer processing can be reduced.
