Filed: 2003-03-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a resin sealed semiconductor device capable of preventing a wire from being disconnected while suppressing an influence of thermal stress happening owing to a difference of coefficients of thermal expansion.  <P>SOLUTION: A hard protective resin 19 comprising epoxy-based resin and chip coated resin or the like is applied on the surfaces of a semiconductor chip 12 and a wire 16a. With such a construction, it is possible to reduce a difference between the coefficients of thermal expansion of the wire 16a and a resin covering the wire 16a as compared with a structure where the wire 16a and a moderating resin 18b make contact with each other. Therefore, since it is possible to reduce an influence (tensile stress or compression stress) of the resin covering the wire 16a to the wire 16a due to the expansion and compression of the same, thinning and disconnection of the wire 16a can be prevented from occurring, and warpage and any fracture of an alumina substrate 11 caused by the coefficients of thermal expansion of the sealing resin 17 and the alumina substrate 11 or the like or variations of resistance of a printing resistor 13 accompanying the warpage and any fracture can be suppressed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
