Abstract:
1. A manufacturing method of a semiconductor module, comprising the steps of: mounting a structure having an interposer substrate in a test socket, after mounting the structure in the test socket,carrying out an electric characteristic test of said structure, wherein the mounting step includes: an appropriate operation temperature range of said second electronic component mounted over said top face of said interposer substrate is narrower than an appropriate operation temperature range of said first electronic component, thermal conductivity of said second member is lower than thermal conductivity of said first member, the second member has a suction hole for holding the second electronic component, whereas the first member has no suction hole, the mounting step further includes after positioning the first and second planes, sucking an air through the suction hole in the second member to hold the second electronic component by the second section of the test socket in order to move the structure toward the first section of the test socket to apply the load, and the first electronic component has a first surface facing the top face of the interposer substrate and a second surface opposite to the first surface, the second electronic component has a third surface facing the top face of he interposer substrate and a fourth surface opposite to the third surface, the fourth surface of the second electronic component is located higher than the second surface of the first electronic component when the first and second electronic components are mounted over the top surface of the interposer substrate. and the first plane in the second section of the test socket is located closer to a bottom of the recess in the first section of the test socket than the second plane in the second section of the test socket when the second section of the test socket is set on the first section of the test socket to place the structure in the recess of the first section.
