Abstract: 1286085 Making semi-conductor devices WESTINGHOUSE ELECTRIC CORP 15 Oct 1969 [13 Nov 1968] 50666/69 Heading H1K [Also in Division B6] A method of forming openings in a layer of insulating material (e.g. silicon dioxide or silicon nitride) on a substrate (e.g. a semi-conductor material such as silicon) comprises applying a metal layer (e.g. aluminium) on to the insulating layer, bombarding selected areas of the surface of the metal layer with damaging radiation electrons) penetrating into the insulating layer, removing the metal layer (e.g. by etching with sodium hydroxide), and etching the insulating layer (e.g. with a mixture of nitric acid and hydrofluoric acid) to produce openings therein where bombarded. The effect of the bombardment is to increase the etch factor or etching rate of the insulating layer, and in order to avoid continuing the bombardment after the etch factor has reached its maximum, an electric voltage is applied for short periods from time to time across the metal layer and the substrate and the current measured. The current decreases as the rate of increase of the etch factor decreases.

Title: Method and apparatus for recording or reproducing data in an arabic script
Inventor: CHAUDHRY MOHAMMAD S
IPC: B41J3/01
Filed: 1973-11-01
Abstract: 1461413 Strip-perforating machines; justifying type INTERNATIONAL BUSINESS MACHINES CORP 12 Aug 1974 [1 Nov 1973] 50823/73 Heading B6W [Also in Division G4] Data representing an arabic-script character having different forms is recorded or reproduced in a form dependent on the following data. A typewriter with a "golfball" print head for printing in arabic script (arabic, Persian, Urdu) uses upper and lower ease respectively for the full and short forms of characters having both; and lower case for characters having only the full form. Actuation of a character key enters a character code (not specifying the form) into a register, sets a marker bit in the register if the character is one of those having both forms, and gates out the previous content of the register to control the print head. Actuation of the space bar causes case shift if the marker bit is set. Thus a character having both forms is printed in short form when the following data represents a character and in full form when the following data represents a space. In another embodiment, characters (form not specified) from a computer, each serial-by-bit, are converted to parallel-by-bit under control of a ring then gated through two registers in turn to a decode matrix feeding a printer (or tape punch or magnetic tape unit). A space in the first register is detected by logic to append a 1 bit to the output of the second register to select the full form (assuming two forms are possible). The gated output of the second register may also go to a decoder which recognizes a space or character which cannot be attached to the following character in a word to set an extra stage of the second register to suitably control the decode matrix when the next character is passed to it so that a character can be printed in initial, medial, final or detached form selected by the combination of the output of the space-detecting logic (see above) and the output of the said extra stage, i.e. depending on both the preceding and succeeding character/space data. Application to teleprinter and typesetting machines is mentioned.
