Title: Light attenuation quantity adder
Inventor: SATO SHOICHI
IPC: G02B27/28
Filed: 1988-09-30
Abstract: PURPOSE:To obtain an accurate attenuation quantity by polarizing light from a source from linear polarized light to circular polarized light through a 1/4- wavelength plate before the light is incident on an ND substrate. CONSTITUTION:The 1/4-wavelength plate 13 and ND substrates 2 and 3 are arranged on the optical axis. Namely, when the light 4 from the light source 1 is linear polarized light, the light is converted into circular polarized light 14 by passing through the 1/4-wavelength plate 13. Then when the ND substrate 2 or 7 is arranged, the transmitted light does not change in polarized state and is measured by a optical wattmeter and when there are two ND substrates, the circular polarized light transmitted through the ND substrate 2 is transmitted through the ND substrate 7 as it is and measured by the optical wattmeter 3. The polarized state is not changed irrelevantly to whether one or two ND substrates are provided, so the addition rule of the accurate attenuation quantity holes. Thus, the accurate attenuation quantity is obtained.

Title: Semiconductor device
Inventor: KURAISON TORONNAMUCHIYAI
IPC: H01L21/70
Filed: 1989-09-26
Abstract: PURPOSE:To secure a mechanical strength and to sufficiently reduce a substrate resistance by a method wherein a conical hole whose depth does not reach an active region is made in the rear of a semiconductor substrate and the hole is filled with a metal which is used as an electrode on the rear. CONSTITUTION:A conical hole 30 whose depth does not reach an active region is made in the rear of a semiconductor substrate 3; the hole is filled with a metal which is used as an electrode 40. A resistivity of the metal is lower than a resistivity of a semiconductor; a contact area of the metal with the semiconductor substrate is increased. As a result, even when the semiconductor substrate 3 is formed in a thickness needed to secure a required mechanical strength, a substrate resistance can be reduced sufficiently. In addition, since a buried depth of the metal does not reach the active region, a device characteristic is not deteriorated. Thereby, it is possible to sufficiently reduce the substrate resistance while the mechanical strength of the semiconductor substrate is secured.
