Title: Signal processing system
IPC: H01J37/304
Filed: 1974-05-03
Abstract: 1427695 Alignment of semi-conductor subtrates INTERNATIONAL BUSINESS MACHINES CORP 3 May 1974 [8 June 1973] 19453/74 Heading H4D In the manufacture of semi-conductors, minute and very accurate patterns must be formed in the photoresist, on the surface of the semi-conductor wafer. If each of a plurality of chips formed on the surface of the semi-conductor wafer is to have the same characteristics and pattern it is necessary that an electron beam or beam of charged particles used to expose photoresist material be moved in such a fashion that any point within the field to which the beam is applied is always reached by the same history. This requires that patterns produced by a beam be properly registered with respect to previously generated patterns. This registration is accomplished by scanning previously placed registration marks on the chip with a beam of electrons and monitoring the reflected or back-scattered electrons to determine where the beam crosses said registration marks. The signal/noise ratio of the signal is first improved by adding corresponding samples of successive scans, followed by a rapid crosscorrelation between the averaged signal and reference signal having certain specific and especially desirable characteristics for example an ideal noiseless signal. The final step utilizes a least squares curve fitting procedure tuned up to extract for example the centre of the crosscorrelation, with a minimum of on-line computation.

Abstract: 837,074. Gasefying powdered coal. SUMITOMO CHEMICAL CO. Ltd. June 20, 1958, No. 19775/58. Class 55 (1). Pulverized coal entrained in such media as oxygen or water vapour is gasefied by an automatically-controlled process in which the total amount of oxygen required for gasefication is supplied partly from the oxygen used to transfer the coal from the feeder to the burner (preferably this comprises 80-90% of the total oxygen), and partly from oxygen from another source (20-10%) which is mixed into the coal stream at the entry to the burner, the temperature of the gasefication being automatically controlled by adjusting the amount of oxygen supplied by this latter source. As shown, an embodiment comprises a furnace 1 containing burners 2 (subscripts are ignored). Entrained pulverized coal passes from feeder 3 through supply rate detector 5 which governs adjustment meter 6, which meter controls valve 7, and is mixed in turn with oxygen which enters through 9 and water vapour which enters through 10. At the burner 2 the mixture is mixed with the oxygen of the second source which enters at 11, and with water vapour which enters at 12. Parts 13, 14, 15 and 16 are flow detectors connected to flow adjustment meters 17, 18, 19, and 20, which control valves 21, 22, 23 and 24, and hence the flow rates of oxygen and water vapour. The overall flow of oxygen to burner 2 from the second source is controlled by meter 26 which is connected to temperature detector 25, suitably a pyrometer. The overall flow of water vapour from the second source is similarly controlled by meter 28 which is governed by carbon dioxide detector 27, suitably an infra-red detector.
