Title: Semiconductor device
Inventor: SUZUKI HITOSHI
IPC: H01L23/50
Filed: 1988-04-18
Abstract: PURPOSE:To reduce the cost by directly bonding a copper wire to the surface of an inner lead having specified surface roughness to be wire-bonded. CONSTITUTION:The surface of an inner lead portion 5 to be wire bonded has 1 to 40 mum surface roughness, to which surface a copper wire 1 is directly bonded. The roughened surface of the inner lead portion might cause plastic deformation upon bonding with ease and destroy an oxide film, so that satisfactory bonding strength could be assured even with direct bonding without plating. Thus, no plating is required on the inner lead portion to reduce the device cost.

Abstract: PURPOSE: To facilitate high filming of molten metal and to cool the metal at high speeds in a high speed quick cooling method by which the molten metal is stuck or touched to substrates by heating the substrates beforehand.  
     CONSTITUTION: Molten metal is stuck or touched as drops or flow to base plate of good heat conductivity which are heated beforehand to ≥100°C. Here it is most preferable to heat the base plate at such temps. at which the difference in temps. between the base plate and the molten metal is min. required to the extent of avoiding the local solidification and increase in the viscosity of the molten metal at the contact surfaces. However, they are heated to ≥100°C in view of easy removability of water. It is recommended to determine optimum temps. in accordance with the kinds of the molten metal, sticking or touching means, etc. as they vary with these. If the base plate are heated beforehand in this way, the local solidification and the increase in the viscosity of the molten metal at the contact surfaces of the molten metal and the base plate are averted, the formation of thin films is made easy, the molten metal spreads sufficiently thinly before solidification on the base plate and the entire part is quickly cooled effectively.

CONSTITUTION:A blanket has a base construction that a compressed layer is laminated on a base fabric. The compressed layer to be laminated on the base fabric contains voids having factors of shape, such as a roundness (SFO) of 0.3 <= SFO <= 1, an acircularity (SFS) of 1 <= SFS <= 2.5, and a circle equivalent diameter (HD) of 5 mum <= HD <= 100 mum, 80% or more to the total amount of voids. The shape having the aforesaid factors of shape is basically a shape of hexagonal system crystal and normally a cube. In the forming of the compressed layer, normally a rubber composition mixed with powders is applied to the base fabric by a roll coater, etc.-only one period at end of sentence. The use of the cubic powders in the blanket for printing eliminates the possibility that the powders are longitudinally orientated in the application of the rubber composition. In this manner, a compression permanent strain can be improved.
