Patent JP-H1174343-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: EGUCHI KOHEI
IPC: H01L21/76
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To enable flat formation without unevenness caused on a surface of a trench-type element separation region, by performing thermal treatment on a first insulation film formed in a trench to make it highly dense, and by performing thermal treatment on a second insulation film embedded in a recess corresponding to the trench to make it highly dense. SOLUTION: In forming an element separation region 10, after a trench is filled with a silicon oxide film 6, thermal treatment is performed, thereby making the silicon oxide film 6 highly dense. In addition, after another silicon oxide film 8 is formed on the silicon oxide film 6 and a butting part 7 is completely filled, thermal treatment is performed on the silicon oxide film 8 to make it highly dense. Therefore, a laminated state in the vicinity of the butting part 7 where filling in the trench 4 is insufficient can be made to be highly dense. Further, filling of the two silicon oxide film layers 6, 8 in the vicinity of the butting part 7 can be more rigid. Thus, a semiconductor device with electric characteristics improved can be manufactured.

Abstract: PURPOSE:To increase the number of wafers subjected to a thermal treatment per batch by a method wherein an increased heat capacity part is provided on at least one of the gas introducing inlet side end part and the opening side end part of a straight tube part and the rate of heat radiation to the heat capacity of that part is reduced and the temperature decline at that part is suppressed. CONSTITUTION:Thick parts 1c and 1d are formed solidly on the outer circumferential parts of a straight tube part 1a, i.e., the gas introducing inlet 2 side end part and the opening part 3 side end part through which semiconductor wafers are carried in and out, as increased heat capacity parts where the heat capacities of both the end aprts are increased. The heat capacities of the thick parts 1c and 1d are controlled by adjusting the lengths and thicknesses of those parts. The heat capacities of the inlet 2 side end part and the opening 3 side end part become larger compared to the capacity of the middle part and the rate of heat radiation to the heat capacity is reduced at both the end parts. With this constitution, the temperature decline at those parts is suppressed and the number of wafers subjected to a thermal treatment per batch can be increased.

The output of the detector 13 is supplied to a narrow zone level meter or a measuring instrument 14 such as a spectrum analyser. When the light is passes through the fiber tunable etalon 12, it is converted to the output as shown by the broken line 21 is the central wavelength lambda0 is coincided with the wavelength showing the max. permeability in etalon characteristics. When there is fluctuation in the wavelength of the light from the light source, amplitude is limited as shown by the broken line 22. This is outputted in such a state that the change of the wavelength is converted to the change of amplitude. As the result, AM, FM noise characteristics of the light from the light source can be measured in high sensitivity.

Title: Evaluation of dielectric insulating isolation substrate
Inventor: INOUE HIRONORI
IPC: H01L21/762
Filed: 1980-12-01
Abstract: PURPOSE:To enable to measure thickness of a dielectric insulating isolation substrate having high precision simply and speedily by a method wherein the  Michelson infrared interference method is applied to measure thickness of a single crystal island of the dielectric insulating isolation substrate. CONSTITUTION:Near-infrared rays having large transmissivity to Si, for example, is made to be injected having the angle of incidence theta from the surface on the single crystal wafer 1 side of the dielectric insulating isolation substrate 8 prior to completion of abrassion work. Reflected light L1 from the surface and reflected light L2 from the boundary between the wafer 1 and an SiO2 film 3 are introduced to a Michelson interferometer 9. Delay of wave (the difference between the optical paths x) corresponding to a round trip of optical thickness to be generated by thickness (t) of the wafer is generated between rays L1,L2. At this time, with regard to interference of light, because the relation between the refractive index eta of Si, the incidence theta, thickness of the island (t), the difference (x) between the optical paths can be formulated, thickness (t) can be obtained by measuring (x) when eta, theta are known. Namely, when merely transferred distance (x) of a transferrable reflector Mb corresponding to the difference between the optical paths (x) is measured precisely, thickness (t) can be obtained.
