Filed: 1974-03-11
Abstract: 1460599 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 11 March 1974 [16 March 1973] 10708/74 Heading H1K In a memory element having the structure of an IGFET (Fig. 2) with a floating gate 7<SP>1</SP> the gate is charged by injection of hot electrons generated by avalanche breakdown of the source or drain junction and discharged by leakage through the boron-doped oxide 13 occurring on application of a suitable voltage to erase electrode 61. As described the gate is of boron-doped polycrystalline silicon and is surface oxidized to produce oxide 13 which exhibits a sharply voltage-dependent leakage current enabling erasure with a positive 30 volt pulse of about 100 millisecond duration. The structure shown includes an IGFET accessing switch connected between the drain 11 of the memory FET and the bit sense line. Simultaneous application of a -30 volt 10-100 Ásec. pulse to the bit-sense and word lines causes negative charging of the gate as described above. With the erase electrode grounded longterm storage is possible but application of the positive pulse thereto quickly discharges the gate. Implantation of the channel with phosphorus may be used to lower the breakdown voltage of the drain junction and the device designed so that the erase electrode-gate capacitance is small relative to that between gate and substrate, enabling the use of a lower erase voltage.

[Also in Division G3] In a heat-exchanger for the production of oxygen enriched air comprising a large number of small tubes mounted vertically between headers comprising upper and lower tube plates, previously cooled incoming air is passed in gaseous form over the lower part of the exchanger on the outside walls of the tubes which are retained at a sufficiently low temperature as to condense some of the air into a liquid mixture of oxygen and nitrogen which is subsequently fed into the top of each tube so that it trickles down the inside walls and is gradually evaporated by incoming air on the outside of the tubes. The cold produced by this evaporation serves to maintain the tube walls at the required low temperature. An adjustable flow regulating device (see Division G3) is fitted into each tube to ensure that the flow in any tube is kept within 10% of the average flow for all of the tubes.
