IPC: B22D11/04
Filed: 1987-04-13
Abstract: PURPOSE:To increase casting speed and to reduce wear of a mold by measuring inner wall temp. of each side of the mold, driving supporting rolls at outlet side of the mold so that the temp. measured value becomes equal at each correspondent position, to execute position control of a cast billet. CONSTITUTION:Plural thermometers 16 are in order buried at each correspond ent position of upper and lower sides and right and left sides in the mold 8. Further, the supporting rolls 30 having adjusting device 22 are arranged at outer side of the mold 8 to control the position of the upper and lower direction and the right and left direction of the cast billet 11. The inner wall temps. of the mold 8 are measured at plural points by the thermometers 16 and input to controlling unit 18, to control the adjusting device 22, so that the temp. measured values at the correspondent positions become equal. By this method, the supporting rolls 20 are advanced/retreated to control the position of front/ rear and right/left directions of the cast billet 11. Therefore, solidified shell 10 is uniformized and resistance to drawing is reduced, and the casting speed is increased and the wear of the mold 8 is reduced.

IPC: H01L21/60
Filed: 1987-04-13
Abstract: PURPOSE:In case of bonding between a pole of semiconductor and an outer lead wire by the titled wire, to provide the wire with toughness and to enable to easily form a heat-melted ball at the tip of the wire which has sperical shape, suitable hardness and hardly disconnect from the tip of the wire by heat cycle, by adding specific ratios of P and Zr to high pure copper and forming a bonding wire. CONSTITUTION:The bonding wire is formed by the copper alloy in which, by weight, 0.003-0.02% P and 0.02-0.015% Zr are added to the high pure copper having >=99.99% purity. In this bonding wire, the neck disconnection at the time of bonding can be eliminated since the coarseness of crystal grains is suppressed by the addition of P. The wire breaking at the tine of bonding can be furthermore suppressed and semiconductor chip cracks can be prevented since the ball hardness and workability are suitably regulated by the incorporation of specific ratio of Zr into said alloy.
