Title: Manufacture of semiconductor wafer
Inventor: IIZUKA NAOTO
IPC: H01L21/304
Filed: 1988-07-02
Abstract: PURPOSE:To contrive the improvement of smoothness of the whole surfaces of the chamfering parts of semiconductor wafers by a method wherein a plurality of sheets of the semiconductor wafers subjected to a mechanic chamfering processing after a lapping process or an entire surface etching process are pinchingly laminated, the laminated material is dipped into an etching liquid and the chamfering parts only are etched. CONSTITUTION:A laminated material X is placed and clamped between a fixed supporting wall 8 and a movable pressing wall 10 of a clamping device Y and is dipped into an etching liquid W in a container H in a state that semiconductor wafers 2 are adhered closely to one another. In this state, as chamfering parts 12 only of the wafers 2 are exposed in the liquid W, the parts 12 only result in being etched as shown by dotted lines, for example. Parts, which are adhered closely to one another, of the wafers 2 are never subjected to etching as never coming into contact with the liquid W. In such a way, the parts 12 only of the wafers 2 are etched.

Abstract: PURPOSE: To eliminate areas of low temperature by connecting a comb-like conductor group to a pair of bus lines on an electrical insulating substrate by providing a parallel stripe group of resistance material having a positive temperature coefficient(PTC), and by performing heating along the bus lines. CONSTITUTION: A group of comb-like electrodes 32 and 34 are connected to a pair of bus lines 16 and 18 on an insulating substrate 14 to form a parallel stripe group from a PTC material 40. The bus lines have electrical resistance in the longitudinal direction, and heating is carried out along the bus lines. The width of a stripe of the material 40 is changed to acquire a desired output density in a desired region. Moreover, the bus lines 16 and 18 have diminishing tapers from power terminals 20 and 22 to the free ends of the bus lines, forming a desired output distribution in the longitudinal direction. A heating part of variable size and shape is placed on a bus line network between adjoining electrode groups, and is sepalated from adjacent heating parts in a clearance space of variable size and shape.  The output distribution over the entire substrate is regulated by the change in density of heating distribution groups. After a protective cover 54 has been stripped, a heating apparatus 12 is installed on a back face of a mirror 10 under the action of an adhesive layer 52 on an insulation barrier layer 50, and is used by connecting the terminals 20 and 22 to a power source to effectively prevent the mirror 10 from being blurred.
