Abstract: There is disclosed offset top ejection apparatus for use in vapor deposition chambers which provides a uniform contaminationfree layer on top of a spinning susceptor plate. The uniformity of the layer is assured by providing an offset downwardly pointing nozzle which is off-centered from the revolving susceptor and from which the deposited material emanates. The arrangement of apertures and the taper of the conical nozzle defines the extent and uniformity of the resulting layer in the offset configuration. Off-setting an ejection nozzle permits a larger area to be uniformly coated resulting in a higher yield for semiconductor wafers carried by the rotating susceptor plate and on which are deposited a layer of dielectric, passivation or other material.

Abstract: In a shared contact electrically programmable read only memory, decoding circuitry is provided to prevent unwanted device programming due to sneak paths to ground. A two input NAND gate (15, 16) is coupled between adjacent column select lines. If either of the adjacent column select lines are energized, a data line will be enabled. Thus, for each column line energized, only two data lines will be enabled and only one of these will carry a voltage for enabling a memory device.
