Title: Semi-conductor device manufacturing method
Inventor: KANEKO HARUO
IPC: H01L21/339
Filed: 1978-06-30
Abstract: PURPOSE:To arrange two layers of gate electrodes at very narrow intervals without allowing them to be overlapped by selectively etching poly silicon at its own adjustment. CONSTITUTION:Doped poly Si 3 is piled on an n type Si base plate 1 through a gate oxide film and etched by Si3N4 masks 41 and 42... to prepare No.1 layer gate electrodes 31 and 32... and then its side is covered by an oxide film 5. Non-doped poly Si 6 is piled after eliminating the masks and heat treated to disperse phosphorus from the electrodes 31 and 32... When the layer 6 is selectively eliminated by utilizing the etching speed difference and selecting an appropriate time, it is possible to obtain electrodes 31 and 32... and electrodes 61 and 62... which are arranged by maintaining extremely narrow intervals with films 5 and free from overlapped sections. CCD memory is formed by covering with CVDSiO2 7, opening hole selectively and providing aluminum wiring 8. It is possible, in this mechanism, to reduce binding capacity between the gate electrodes and improve the CCD memory performance.

Patent JP-H01251762-A (JP)
Title: Image sensor
Inventor: ITAGAKI MASAKUNI
IPC: H01L31/08
Filed: 1988-03-31
Abstract: PURPOSE:To enhance the arrangement accuracy of elements in a bonding part of a substrate and to prevent deterioration of the resolution by a method wherein the direction of abrasive scratches due to an abrasive on each end face are nearly parallel to the substrate face where an optoelectric transducer has been installed and the surface roughness at each end face is 5mum or below. CONSTITUTION:After a substrate 1 has been cut at its end part, an end face (a) is polished by using a polishing grindstone whose grain size is 200 mesh up to a desired position in such a way that the face is perpendicular to an element surface (b). When the end face is polished at 2000 mesh, the unevenness at the end face and a chipping become 5mum or lower. In the case of a cutting operation by a dry scribing method, the unevenness and the chipping are comparatively small; accordingly, the cutting operation is executed at a part by 20-30mum at the outside. By this setup, it is possible to reduce the scattering of an incident beam to a minimum and to improve the arrangement accuracy of elements 2. In addition, when the direction of a polishing scratch (d) in the bonding end face (a) is made parallel to the device face (b), it is possible to prevent an adhesive 3 from oozing to the device face.

A mark located at a position different from a specified range over the wafer W is observed by a television camera 56 via a projection lens 18, and resultant focal point position (the position of a substrate) is determined by a signal at which contrast becomes highest when an image forming path is made variable. Regist over the mark has been removed, and a mark range is different from the specified range in height position. The difference in height position due to structural difference is then applied as an off-set to the oblique incident AF system.
