IPC: C30B23/08
Filed: 1984-08-31
Abstract: PURPOSE:To heat uniformly a semiconductor substrate and to prevent the generation of a defect such as slip by forming a space closed by providing a window consisting of a specific material between the compd. semiconductor and heater. CONSTITUTION:The window 13 consisting of the material (e.g: sapphire plate) which is transparent to relatively short wavelength light and is opaque to about 10 mum long wavelength light is provided via the closed space 15 to the compd. semiconductor substrate 12 and the heater 16 is provided behind the window 13. The light RD1 of the relatively short wavelength radiated from the heater 16 transmits the window 13 and heats the substrate 12. On the other hand, the light RD2 of the long wavelength radiated by the heated substrate 12 is blocked by the window 13 so that the element trying to dissociate from the rear surface of the substrate 12 is confined in the space 15. The element pressure PI in the space 15 is thus made much larger than the element pressure PO on the outside, by which the progression of the dissociation of the element is prevented.

Title: Signal editing method
Inventor: NATSUME AKINORI
IPC: G06F19/00
Filed: 1992-07-09
Abstract: PURPOSE:To provide a signal editing method which can eliminate the discontinuity of the signals and the fine coefficients of signals which are caused at the end point of a limited section by the magnification or reduction of signals. CONSTITUTION:The degree of magnification or reduction is defined as the output rate of the secondary delay which is set with input of the smaller distance of the start or end point of a relevant section. Therefore, the degree of magnification or reduction is small at a point slightly distant from the end point. Meanwhile, the secondary delay output is equal to '1' at a point distant enough from the end point and the ordinary magnification or reduction is carried out. Thus, it is possible to evade the discontinuity of signals and the fine coefficients of signals which are caused in a section to be magnified or reduced.
