摘要： Solder is connected to the electrodes of the circuit board by using a temperature profile with a constant fusion temperature, a connection interface strength evaluation test is carried out on the soldered joints to obtain an appropriate reflow range free of decreases in the strength at the connection interface. On the basis of the appropriate reflow range obtained and using as the basis the chemical compound thickness which is determined uniquely by heat load, an appropriate reflow range in an optional temperature profile with one temperature peak is obtained. By carrying out connection in this appropriate reflow range, soldered joints can be obtained without decreases in the connection interface strength in the large-scale production stage.

摘要： For high density packaging of a semiconductor device, the semiconductor device has a multi-layer substrate, a first-stage chip connected electrically to the multi-layer substrate, other package substrates stacked in three stages on the multi-layer substrate and each connected to an underlying wiring substrate through solder balls, second-, third- and fourth-stage chips electrically connected respectively to the other package substrates, and solder balls provided on the bottom multi-layer substrate. The number of wiring layers in the bottom multi-layer substrate which has a logic chip is larger than that in the package substrates which have memory chips, whereby the semiconductor device can have a wiring layer not used for distribution of wires to the solder balls and wiring lines in the wiring layer can be used for the mounting of another semiconductor element or a passive component to attain high density packaging of the semiconductor device as a stacked type package.
