Abstract

A carrier for a stacked type semiconductor device includes a lower carrier having a first accommodating portion that accommodates a first semiconductor device, and an upper carrier having a second accommodating portion that accommodates a second semiconductor device stacked on the first semiconductor device so as to be placed in position on the first semiconductor device. It is thus possible to eliminate an additional device used for stacking the semiconductor device, and thereby reduce the cost.

Claims (18)

1. A method of fabricating a stacked type semiconductor device comprising the steps of:

placing a first semiconductor device in a lower carrier of a stacked type semiconductor device carrier;

stacking a second semiconductor device on the first semiconductor device by using an upper carrier of the stacked type semiconductor device carrier; and

fixing the first and second semiconductor devices together.

2. The method as claimed in claim 1 , wherein the step of stacking comprises the steps of attaching the upper carrier to the lower carrier; and then placing the second semiconductor device in the upper carrier.

3. The method as claimed in claim 2 , further comprising the step of making an electrical connection between the first and second semiconductor devices accommodated in the stacked type semiconductor device carrier in a reflow chamber so that the first and second semiconductor devices are incorporated.

4. The method as claimed in claim 3 , further comprising a step of removing the upper carrier before the stacked type semiconductor device carrier is placed in the reflow chamber.

5. The method as claimed in claim 1 , further comprising a step of connecting pins for testing to the first semiconductor device through an opening of the lower carrier and testing the first semiconductor device accommodated in the lower carrier.

6. The method as claimed in claim 1 , further comprising a step of supplying an adhesive on a sealing resin of the first semiconductor device before the step of stacking.

7. The method as claimed in claim 6 , wherein the sealing resin is thermosetting resin.

8. The carrier as claimed in claim 1 , wherein:

the second accommodating portion of the upper carrier has an inserting opening through which the second semiconductor device is accommodated in the upper carrier; and

the inserting opening gradually becomes wider towards an upper end of the inserting opening.

9. A method of fabricating a stacked type semiconductor device comprising the steps of:

placing a first semiconductor device in a lower carrier of a stacked type semiconductor device carrier; and

stacking a second semiconductor device on the first semiconductor device by using an upper carrier of the stacked type semiconductor device carrier;

wherein the lower carrier comprises a hold member made of an elastic material, the hold member holding the first semiconductor device in the first accommodating portion.

10. The carrier as claimed in claim 9 , wherein the hold member holds side edges of the first semiconductor device.
