    摘要: Oxygen ion is implanted into a silicon substrate to remain a silicon layer on a surface of the silicon substrate. In this state, a silicon oxide layer is formed under the silicon layer. Silicon oxide particles are formed and remained in the residual silicon layer. While maintaining this state, the silicon substrate is heated to a predetermined temperature not less than 1300.degree. C. Alternatively, the silicon substrate is heated at a high temperature-rise rate to 900.degree.-1100.degree. C., and thereafter is heated at a low temperature-rise rate to the temperature not less than 1300.degree. C. The silicon substrate is held at the predetermined temperature not less than 1300.degree. C. for a predetermined time, whereby crystallinity of the residual silicon layer is restored. A pinning effect of the silicon oxide particles prevents the rise of dislocation to the surface of the SOI layer, and also suppresses a rate per a unit time at which interstitial silicon generates during the heating to the high temperature region. Therefore, a dislocation density of the SOI layer can be reduced.

    摘要: Disclosed is an apparatus for detecting the three-dimensional configuration of an object employing an optical cutting method. A light projector pulse-flashes slit-shaped light and causes the light to scan an object at a predetermined speed. An image sensor having a plurality of pixels is disposed in opposition to the object. An optical system forms on the image sensor an image of an optical cutting line formed on the surface of the object by the light. Counters each count the number of pulses of the image of the optical cutting line that has been detected by each pixel. A time calculator calculates the time at which the image has passed each of the pixels, on the basis of the counted numbers of pulses. A configuration calculator calculates the three-dimensional configuration of the object on the basis of the calculated passage time and the scanning speed of the slit-shaped light. Because the counted numbers of pulses, which are each indicative of the period of time required for the image of the optical cutting line to pass each pixel, are used to calculate the passage time, there is no need to provide a data bus to transmit time data with respect to the each pixel. Thus, the apparatus has simple wiring arrangement, and can be manufactured with ease.
