[Also in Division H3] A junction diode is made by short-circuiting the emitter and base or the collector and base of a junction transistor. In a solid circuit device incorporating two identical planar transistors (Fig. 2), an aluminium electrode 15 is deposited on the base-collector junction 11 of one of the transistors in order to form a junction diode. An AND gate (Fig. 6) is made by depositing gallium on to an N-type Si wafer 80 of resistivity 105 ohm cm. and then selectively etching the surface as at 89, 79 and 76. Phosphorus is then deposited through a mask to form N-type regions 84, 89, 79 and 94. Finally, A1 is deposited, thereby forming electrodes for diode D1 (a diode D2 not shown). Transistor T and a bias resistor RE which comprises a portion 77 of the P-type layer. The A1 layer 85 serves to short circuit PN junction 81 and to connect the diode to a resistor RB formed by a portion 72 of the P-type layer. Positive and negative battery are connected to terminals 74 and 78 respectively and the output of the gate appears on terminal 73. Wire 101 which links the emitter 93 of transistor T to the output terminal and wire 102 which couples the diode to the transistor base may be formed by depositing A1 on to a suitable insulating layer formed on the wafer. The short circuiting of junction 81 may be achieved by discharging a capacitor between opposite faces of the wafer as is disclosed in Specification 908,553. The use of PNIP and NPNN+ structures in the manufacture of the diodes is also mentioned.

Abstract: 1441817 Instruction buffering arrangements INTERNATIONAL COMPUTERS Ltd 19 June 1974 [19 July 1973] 34429/73 Heading G4A Multi-word blocks of instructions are held in a slave store 10 of smaller capacity and faster access time than a main store 100 from which the blocks are derived. An instruction buffer 26 holds a single instruction block and is divided into two unequal sections 31 and 32 to 34, one section being loaded from store 10 while instructions in the other section are being read out for execution whereby the longer period provided for loading the smaller section 31 of the instruction buffer 36 allows transfer of the next instruction block from main store 100 to slave store 10 to take place if that block is not already in store 10. As described each block comprises 4 words and each word may comprise either a full length instruction (32 bits) or two half length instructions (16 bits). Slave store 10 holds 16 blocks of 4 words 11-14, words 12-14, of an addressed block being transferred to buffer 26 while word 11 is being gated out from the buffer and vice versa. Two sets of read out gates 35, 36 are provided, a corresponding gate A-H in each set being enabled to select half words from buffer 26 in response to the output of the decoder 40 in an instruction counter circuit comprising a current address register 41, and an adder 43 incrementing the address by plus 1 or plus 2 depending on whether half or full length instructions are involved. The current block address is held in a register 67 and is incremented by plus 1 in an adder 91 before passing to a next instruction register 70, e.g. at the start of scanning the second section 32-34 of the buffer 26. The block address in register 70 is used as a search argument for an associative store 71 which contains a table of addresses of blocks already in slave store 10. If a match is found store 10 is addressed directly over path 15, if not a block address is passed from register 70 to access main store 100, the block read out being supplied to store 10 over paths 102, 21 to over-write a previous block selected by suitable replacement mechanism, e.g. a least recently used pointer. Jump and interrupt addresses may be applied over paths 58, 59 as a substitute for normal incrementing of the block and word addresses.
