Title: Method of Dicing Semiconductor Wafers
IPC: H01L21/304
Filed: 1969-02-12
Abstract: 1,193,945. Splitting stone. R.C.A. CORPORATION. 12 Feb., 1969 [23 Feb., 1968], No. 7610/69. Heading B5E. [Also in Division H1] A scribed semi-conductor wafer 10 is mounted between two flexible diaphragms 36, 38, e.g. of rubber, and a force is exerted against the diaphragm 36 in contact with the unscribed face to flex the diaphragm and the wafer into an arched configuration and thus to break the wafer along the scribed lines. In the apparatus shown the flexing occurs into a cavity 28 of a lower block 24 under the action of excess air pressure introduced into a cavity 26 in an upper block. Reverse flexing may also occur if means are provided for subsequently applying excess air pressure to the cavity 28, this being particularly useful when the unscribed face of the wafer 10 has a metal covering, e.g. of lead. In an alternative apparatus the wafer is mounted, scribed face down, between two aluminium foils and two spring steel diaphragms over a cylindrical groove (52), Fig. 7 (not shown) in a block (51). A brass cylinder (64) is used to urge the resulting sandwich down into the groove (52), breaking the wafer along the scribed lines parallel to the groove axis. The procedure is repeated with the wafer turned through 90 degrees to break it along the other set of scribed lines.

Abstract: 998,888. Cooling charge; regulating. SULZER FRERES S.A. Feb. 26, 1963 [Feb. 26, 1962], No. 7698/63. Heading F1B. The air supply to a gas or dual fuel engine is heated at partload by exhaust gases added thereto through a connection 4 between the exhaust and intake manifolds 2, 3, a valvecontrolled by-pass 43 around a cooler 44 for the intake air being open while the valve 4 is open and progressively closed as engine output increases after valve 4 is closed. The exhaust manifold 4, Fig. 1; is connected to the inlet manifold through a valve 5 operated by oil pressure set up by a pump 22 in a circuit 21. In the dual fuel engine shown the gas inlet valves are operated hydraulically by pumps 8 and liquid fuel is injected by pumps 7, the control rods 11, 10, of the pumps being connected to a floating lever 12 actuated through links 13, 14, by a governor 15 the setting of which is controlled by a lever 20. For gas operation a slide 31 is moved to the left by handle 33 and on increase of load the lever 12 pivots to increase the gas supply up to the-maximum set by sleeve 31, after which the lever 12 moves rod 10 to increase the liquid fuel supply beyond the pilot amount necessary for ignition determined by stop 28. The pressure in circuit 21 is limited by a relief valve 24 and is controlled by valves 25, 26. With maximum pressure in circuit 21 valve 5 is lifted to divert the exhaust into the air inlet manifold. During operation on liquid fuel, as soon as rod 10 moves beyond the pilot injection position, valve 25 is opened to reduce the pressure in circuit 21 and close valve 5 so that no exhaust gases are admitted to the inlet manifold. For operation on gaseous fuel; valve 25 is closed and valve 26 is increasingly opened by lever 20 as the load is increased so that the pressure in circuit 21 is gradually reduced and the supply of exhaust gases to the inlet manifold gradually decreased. The air is compressed in a turbo charger 41 and passes through a cooler 44 having a by-pass controlled by a valve 43 which is also controlled by the pressure in circuit 21 so as to be open to by-pass cooler 44 when valve 5 is open and closed to force the air through cooler 44 when valve 5 is closed. In a modification, Fig. 2, the air from turbocharger 41 passes through a cooling arrangement consisting of a cooler 52, compressor 50, cooler 53 and expansion turbine 51, the whole being provided with a by-pass 45 controlled by valve 43. Specification 994,816 is referred to.

Abstract: 1,256,148. Coiling; bending by rolls. REPUBLIC STEEL CORP. 14 Feb., 1969 [20 Feb., 1968], No. 8072/69. Heading B3E. [Also in Divisions F2 and G3] In a method and apparatus for coiling strip, defined as meaning any elongate material to be wound into a coil such as rod, wire, bar or tubing, the strip is bent in a bending station prior to winding, the outer turns of the coil being as near as possible to the part of the strip being bent so that the strip is not unbent after bending and before winding on the coil. The apparatus comprises bending rolls 578-1A and 578-1B on one side of the strip and a plurality of smaller rolls 551-11 on the other side of the strip between the strip and the coil. The coil is wound on to a winged spool the wings of which can be swung toward the centre of the spool for removal of the coil. The spool is mounted pivotably about a column 527-1 so that it may be swung clear of a frame carrying the bending apparatus. A system of cams and levers connects one of the bending rolls 578-1B to the mounting carrying the spool such that as the wound diameter of the spool increases, the outer turns bearing on rolls 552-4 and 552-6 cause the mounting to pivot and the levers act on the roll 578-1B to move it away from the coil thereby increasing the radius of the bend put into the strip. The spool is moved in translation past the bending station to wind successive turns on to the coil by a fluid operated cylinder controlled by a ratchet driven valve (see Heading G3P), the ratchet being driven from the motor which drives the spool and being so adjusted that the spool moves one strip width in translation for every turn of the coil. A delay mechanism allows the end turn of a successive layer of the coil to be wound above the last turn of a lower layer.
