Abstract: 1,236,404. Integrated circuits. INTERNATIONAL BUSINESS MACHINES CORP. 9 May, 1968 [23 May, 1967], No. 46663/70. Divided out of 1,236,401. Heading H1K. The disclosure is identical with that of Specification 1,236,401 from which the present application is divided but the claims relate to a semi-conductor wafer comprising a plurality of areas each including a number of devices interconnected to form a circuit, the areas being in a co-ordinate array to permit dicing by intersecting sets of cuts and each being provided with a graded mark on two of its edges to permit a visual indication of the accuracy of dicing.

Abstract: 1,236,402. Integrated circuits. INTERNATIONAL BUSINESS MACHINES CORP. 9 May, 1968 [23 May, 1967], No. 46661/70. Divided out of 1,236,401. Heading H1K. The disclosure is identical with that of Specification 1,236,401 from which the present application is divided. The claims are to an integrated circuit comprising a semi-conductor substrate having formed therein a sufficient number of semi-conductor devices to permit of interconnection to form one of a plurality of different circuits with spare capacity, and a plurality of terminal structures spaced around the area containing the devices, the devices including a number of resistors each consisting of a region of one conductivity type located in region of opposite type common to all the resistors.

Abstract: 1,236,403. Integrated circuit resistors. INTERNATIONAL BUSINESS MACHINES CORP. 9 May, 1968 [23 May, 1967], No. 46662/70. Divided out of 1,236,401. Heading H1K. The disclosure is identical with that of Specification 1,236,401 from which the present application is divided. The claims are to a resistor comprising a substrate of one conductivity type (say P type) with an elongate low resistivity inclusion of the opposite (N) type in one surface coverisd by a high resistivity N type region surrounded by an isolating ring which extends to the substrate, the region having in its surface a pair of elongate low resistivity N type contact regions disposed near the ends of the aforementioned inclusion with their axes orthogonal to its axis, and having a length exceeding the width of the inclusion at the respective points of crossing.
