To cause a crack at a fixed position in a separation layer, a method of separating a composite member includes the steps of forming a separation layer inside a composite member, forming inside the separation layer a stress riser layer in which an in-plane stress has concentratedly been produced to an extent that does not cause separation by the in-plane stress, and enlarging the in-plane stress to cause a crack in the stress riser layer, thereby separating the composite member.

A process for producing a semiconductor substrate comprises the steps of forming a porous layer in a first substrate comprising monocrystalline silicon; forming a protective film on a side wall of the pores of the porous layer; forming a nonporous monocrystalline silicon layer on the porous layer; bonding the surface of the nonporous monocrystalline silicon layer onto a second substrate with interposition of an insulating layer; and etching off selectively the porous layer by use of a chemical etching solution.

With a method according to the invention, a semiconductor article such as an SOI substrate having on the surface thereof a single crystal silicon film formed on an insulator is etched by heat treatment in a hydrogen-containing reducing atmosphere in order to remove the surface by a desired height and smooth it. The method is characterized in that the single crystal silicon film is arranged opposite to silicon oxide in a furnace during the etching process.

In a process for producing a semiconductor substrate, comprising sealing surface pores of a porous silicon layer and thereafter forming a single-crystal layer on the porous silicon layer by epitaxial growth, intermediate heat treatment is carried out after the sealing and before the epitaxial growth and at a temperature higher than the temperature at the time of the sealing. This process improves crystal quality of the semiconductor substrate having the single-crystal layer formed by epitaxial growth and improves smoothness at the bonding interface when applied to bonded wafers this process enables the detection of the smaller particles on the surface by a laser light scattering method.

An output apparatus processes data input selectively from a plurality of host computers and outputs a data processing state. The output apparatus includes an input structure that inputs data selectively from the plurality of host computers, a discriminating device that discriminates from which one of the plurality of host computers the input data is supplied, and an informing device for informing an operator of the output apparatus of the data processing state of the output apparatus in response to a discrimination by the discriminating device. An output method performs the operations of the output apparatus, and can be performed by using a memory medium that stores a program used in a programmable output apparatus. The output apparatus may use a host interface, or a plurality of host interfaces, for the input structure.

A method of forming crystals is adapted to grow a single-crystal by subjecting a substrate having a free surface with mutually adjacent non-nucleation and nucleation surfaces to a crystal forming process. Each nucleation surface consists of an amorphous material, having a greater nucleation density than the non-nucleation surface, with respect to a material with which the single-crystal will be formed, and having an area sufficiently small to permit only one nucleus to be generated, which will grow into the single crystal. The non-nucleation surfaces are made of a material having a higher etching rate than the material of which the nucleation surfaces are made. After a process of implanting ions in the entire surface of the substrate, the resultant substrate is subjected to an etching process whereby the non-nucleation surface material alone is selectively etched to remove the unnecessarily ion-implanted portions of the material. Thus, in the ion implantation, which is performed without employing a resist and followed by selective etching, a great amount of ions can be implanted without involving the conventional problems and without complicating the method. Therefore, it is possible to achieve a sufficiently great difference in nucleation density between the nucleation and non-nucleation surfaces, thereby increasing the yield of crystal growth.
