Title: Chip carrier
Inventor: KINOSHITA MASAKI
IPC: H01L23/28
Filed: 1989-03-31
Abstract: PURPOSE:To obtain a chip carrier, in which a microscopic crack is not generated, by a method wherein a chip carrier, on which a semiconductor element and bonding wires are potted with an epoxy resin, a levee-shaped protruding part is provided on the periphery of the epoxy resin which is potted. CONSTITUTION:A potting resin 5 is applied on a semiconductor element 3 by a pressure-type dispenser or the like. In order to form this resin 5, a resin 5' and a filler 5'' are sufficiently stired and mixed in advance by a jar roller or the like and a vacuum defoaming is performed in a vacuum. Moreover, a protruding part 6 is constituted in advance of a resin, which has a low wettability to an epoxy resin and inhibits the outflow of the resin 5 within a narrow like a fluorocarbon resin, on a chip carrier 1 by a printing or transfer method. As a result, the filler 5'' is uniformly dispersed in the whole potting resin coating layer to obtain a value partially having little fluctuation in a thermal expansion coefficient and this carrier is formed into a chip carrier, in which a microscopic crack is not generated against a thermal shock. Moreover, by setting a wet angle 7 of the resin 5 to the carrier 1 at 45 degrees or larger, the resin 5 on the point parts of bonding wires 4 and the filler can be prevented from being separated from each other.

Abstract: PURPOSE:To produce hexachlorodisilane, in high yield, by the two-stage cracking of the high-boiling component having higher molecular weight than octachlorotrisilane in the product obtained by the chlorination of silicon (alloy). CONSTITUTION:Silicon or a silicon alloy (e.g. CaSi2) is chlorinated at high temperature (300-500 deg.C for silicon and 150-350 deg.C for silicon alloy) to produce hexachlorodisilane. In the above process, the by-produced high-boiling component having higher molecular weight than octachlorotrisilane is heated optionally in the presence of a diluent (e.g. SiCl4) at 300-700 deg.C to decompose at least a part thereof to hexachlorodisilane. The decomposition product is condensed by cooling, and the desired hexachlorodisilane is recovered together with SiCl4 from the condensation product e.g. by distillation. After the separation, the residual high- boiling component having higher molecular weight than octachloro-trisilane is made to react with chlorine at 200-700 deg.C to obtain hexachlorodisilane.
