Title: Soi substrate and manufacture thereof
Inventor: ARIMOTO YOSHIHIRO
IPC: H01L27/12
Filed: 1988-04-11
Abstract: PURPOSE:To enable an element formation layer with improved crystallizability and sufficient amount of mechanical strength to be achieved even in a SOI substrate with a thin element formation layer since a single-crystal silicon thin piece is low-oxygen low-defect crystal purified by the floating band fluxing method. CONSTITUTION:An element formation layer 1 is adhered to a supporting substrate 2 through an SiO2 layer 3. A single-crystal silicon wafer at the side left as an element formation layer 1 of this Silicon on Insulator(SOI) substrate is made to be a single-crystal Si by the floating zone melt method(FZ) or the one where a low-defect area is formed on the surface of a single-crystal Si by the Czochralski method(CZ). Then, a Z single-crystal Si with a greater mechanical strength is used as the supporting substrate. Thus, since the element forming area is practically without oxygen and defect, no defect is produced by heat treatment in the element forming process. Also, use of the Z single- crystal with a larger mechanical strength as a supporting substrate results in no deforming even if the FZ single-crystal is used at the element formation layer.

Abstract: PURPOSE:To obtain a pipe for coating optical fiber which permits mass production, is formable to have a long one span and has high flexibility and pressure resistant strength by cutting independent parallel grooves into a spiral or toric shape on the circumference of an extrusion molded pipe. CONSTITUTION:This pipe for coating optical fiber is formed by cutting the parallel grooves 9 of the spiral or annular shape on the surface of an extruded synthetic resin pipe 8 of a single layer consisting of a medium-hardness resin or of double layers consisting of an outer hard layer 8a and inner soft layer 8b to impact the flexibility and the pressure resistant strength thereto and this process is for producing such pipe. Since the pipe has the grooves 9, the flexibility is imparted to the pipe so that the pipe withstand bending of the optical fiber. The residual parts X of the surface remaining between the grooves 9 resist the pressing from outside. Particularly the extruded synthetic resin pipe 8 of the double layers is capable of sufficiently maintaining the pressure resistant strength and the flexibility. Since the inside wall surface is circular free from ruggedness, the optical fiber is insertable in the long one span at one time into the coating pipe.
