Title: Method and apparatus for measuring double refractive index
Inventor: HORIGUCHI TSUNEO
IPC: G01N21/23
Filed: 1989-11-01
Abstract: PURPOSE:To measure the double refractive indices over a wide range with high accuracy and to measure the distribution of the double refractive indices as well by measuring the magnitude of double refractions by utilizing the mixing of 4 light waves between the light waves propagating in opposition. CONSTITUTION:The light wave 1 which is the continuous wave from a pumping light source L1 is made incident to an optical fiber 2a via a lens l1. The light wave 2 which is the continuous wave from a pumping light source L2 is made incident to the optical fiber 2a via a lens l2. The light wave 1 and the light wave 2 propagate in opposition in the optical fiber 2a. The light wave 3' propagating in the same direction sa the light wave 1 and the light wave 4' propagating in the same direction as the light wave 2 are generated as a result of the mixing of the four light waves of the light wave 1 and the light wave 2 as pumping waves. The light wave 2 and the light wave 4' are converted to the electric signal oscillating at the frequency difference between the light wave 2 and the light wave 4' by a photodetector 4. This frequency is measured by a frequency selecting receiver 5 and is computed by a signal processor, by which the double refractive index is determined.

Filed: 1986-11-29
Abstract: PURPOSE:To use a laser light source of high coherence and to attain a high resolution by providing a light diffusing film in the aperture part of a light absorbing film worked into a mask pattern. CONSTITUTION:A mask for photolithography has a light absorbing film 3 formed on a glass substrate 1, and this light absorbing film 3 is worked into the mask pattern. For the purpose of producing this mask, the glass substrate 1 is set in a plasma polymerizer having an evaporation source 6, and fine raw material particles are evaporated from the evaporation source 6 simultaneously with formation of a high polymer film on the glass substrate 1 by plasma polymerization to form a light diffusing film 2 where fine particles are dispersed in the high polymer film, and thereafter, the light absorbing film 2 is formed on the light diffusing film 2 and is worked into the mask pattern. In this case, no speckle patterns occur in the image forming position because the laser light of high coherence incident on the mask is diffused by the light diffusing film 2, and a high resolution is obtained because the principal part of the diffused light is made incident within the pupil angle.

Title: Pretreatment method of recombination life time measurement of silicon wafer
Inventor: INOUE HISASHI
IPC: H01L21/66
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To enable highly reliable measurement when performing pretreatment for forming an oxide film at 950 to 1,050 deg.C by using a vertical heat treatment furnace before measuring recombination life time of a silicon wafer. SOLUTION: After an oxide film is formed, the temperature of an inside of a heat treating furnace is lowered to 650 deg.C, for example, under inert gas atmosphere and thereafter a wafer is unloaded. Thereby, slippage of a wafer with even a diameter as large as 12 inches, can be restrained. It is also possible to restrain the dispersion in the measurement values of a recombination life time by supplying oxygen gas into a heat treating furnace at least during carrying out of a wafer boat from a heat treating furnace.

Title: Led driving circuit
Inventor: KUROSAWA MITSUHIRO
IPC: H04B10/80
Filed: 1987-11-10
Abstract: PURPOSE:To allow the title circuit to be built in an optical transmitter as a compact circuit by controlling a transistor (TR) circuit so that a voltage applied to an LEd goes high at a high peripheral temperature or goes low at a low peripheral temperature. CONSTITUTION:The TR circuit is connected in series between the LED and a power supply to supply a constant voltage from the power supply to the LED. When the peripheral temperature is raised, respective terminal voltages of plural diodes D1-Dn in an LED temperature compensating circuit 4 are dropped, the base potential of a TR Tr3 is dropped and a difference between the base potential and a voltage determined by a Zener diode ZD is reduced. Since the base current of a TR Tr2 in an LED protection circuit 3 is increased as the result, a terminal voltage V0 is boosted and the drop of output emitted from the LED can be compensated. Namely, the voltage applied to the LED goes high at a high peripheral temperature or goes low at a low temperature. Consequently, the LED driving circuit can be built in the optical transmitter as a compact circuit.
