Abstract: PURPOSE:To elevate the melting point of solder, to prevent the displacement of the position of the attachment of a pellet on wire bonding, etc. and to attach the pellet positively at low cost by mixing a fixed quantity of copper into solder. CONSTITUTION:Solder 3 is manufactured by mixing a small quantity of copper to lead and tin, and the content of copper is selected within a range in which the melting point of solder reaches to 660 deg.C from 350 deg.C. The lower limit value of 350 deg.C is obtained by using the heating temperature of a lead frame 1 as a reference, and the upper limit value of 660 deg.C is acquired by using the melting point of aluminum on thermocompression bonding in the case when an aluminum wire is employed as a wire for wire bonding as a reference. Accordingly, the content of copper extends over 1-4 atomic percent (atomic %). The position of the semiconductor pellet 4 is not displaced due to the melting of solder 3 even on heating at a high temperature of 350 deg.C or more in order to airtight-seal and wire-bond a package.
