Title: Semiconductor manufacturing apparatus
Inventor: MATSUOKA TAKASHI
IPC: H01L21/30
Filed: 1988-02-23
Abstract: PURPOSE:To reduce in size an alignment device and to simplify it by transmitting infrared rays from the rear face side of a semiconductor substrate to detect the reflected rays thereby to recognize a pattern of the front surface when the pattern provided on the front surface of the substrate is used as an alignment mark to form a desired pattern on the rear face. CONSTITUTION:An alignment method is composed of a GaAs wafer 1, an objective lens 2, an infrared ray camera 3, a signal line 4, a CRT monitor 5, and an infrared lamp 6. That is, an infrared ray is transmitted from the rear face of a wafer 1, the differences A', B', C' of the contrasts of the reflected infrared rays are detected through the lens 2 by the camera 3, and displayed on the monitor 5. Here, the pattern of the front surface is recognized by the differences of the contrasts by utilizing the difference of the reflected infrared lights transmitted through the wafer 1 according to pattern materials, such as GaAs, SiN provided on the surface thereof. Thus, the necessity of providing the lens at the lower side of the wafer 1 is eliminated, thereby simplifying the alignment.

IPC: C09B27/00
Filed: 1984-03-02
Abstract: PURPOSE:To obtain a compsn. high in an extent of change discoloration due to light irradiation by using at least one kind of specified naphthalene-1-ONN- azoxybenzene derivs. and a polar solvent. CONSTITUTION:Naphthalene-1-ONN-azoxybenzene drivs. represented by the shown formula are such as naphthalene-1-ONN-azoxy(4'-methylbenzene) and naphthalene-1-ONN-azoxy(4'-methoxybenzene). As the solvent, since the rearrangement reaction of said derivs. proceeds rapidly in a compsn. composed of a colorless transparent polar solvent, especially highly polar solvent, such as ethanol, an extent of discoloration due to light irradiation especially distinguished favorably. Said deriv. is used in an amt. of >=0.001% to facilitate the observation of discoloration. In the formula, R is 1-4C alkyl or alkoxy. Since this compsn. is facilitated in reactivity by light irradiation as compared with a right and left symmetrical type azoxybenzenes, and exhibits distinct discoloration, it is superior for the purpose of display.
