A method of fabricating a semiconductor device includes the steps of providing a heat-resistant sheet on an interposer so as to cover electrode terminals provided on the interposer, and sealing a semiconductor chip on the interposer sandwiched between molds with a sealing material. The electrode terminals are covered by the heat-resistant resin for protection, and the semiconductor chip is then sealed with resin. It is thus possible to avoid the problem in which contaminations adhere to the electrode terminals. This makes it possible to prevent the occurrence of resin burrs on the interposer and contamination of the electrode pads and to improve the production yield.

A method of producing a carrier structure for fabricating a stacked-type semiconductor device includes laminating thin plates for a lower carrier associated with an upper carrier. The method includes forming openings in the thin plates by etching or electric discharge machining. The lower carrier includes a magnet that is buried therein and the magnet maintains contact between the lower carrier and the upper carrier. A thin plate of the laminated thin plates is provided on each opposing surface of the magnet. The lower carrier further includes multiple magnets arranged around a periphery of the lower carrier and through a center region of the lower carrier that is between magnets on the periphery.

The present invention provides a semiconductor device that includes semiconductor packages arranged in a stacked configuration. A plurality of leads are drawn from the stacked semiconductor packages and folded around the outer shape of each semiconductor package such that the leads extend over the upper surfaces of the semiconductor package. Holders affix the stacked semiconductor packages so that first and second leads contact each other, the first leads being drawn from a first one of the stacked semiconductor packages at a lower stacking stage, and the second leads being drawn from a second one of the stacked semiconductor packages at an adjacent, upper stacking stage.

Stacked semiconductor devices and a method for fabricating the same

A method for manufacturing a semiconductor device is disclosed. As a part of the method, one surface of a substrate is molded with resin where the substrate and the resin are heated in a first heating process and maintained in a flat condition. The substrate and the resin are returned to room temperature while being maintained in the flat condition after the first heating process. The resin is cut after the substrate and the resin are returned to room temperature from a surface of the resin that is opposite the surface of the resin where the substrate contacts the resin. The substrate is left intact when the resin is cut. Thereafter, the substrate is separated.

Method for manufacturing a semiconductor device

A carrier for a stacked-type semiconductor device includes an accommodating section for accommodating stacked semiconductor devices, guide portions guiding the stacked semiconductor devices, and grooves through which a fluid may flow to the accommodating section and to sides of the stacked semiconductor devices. These grooves facilitate the flow of gas or liquid on the sides of the accommodating sections, and it is thus expected that the flow of hot wind during the reflow process and cleaning liquid during the cleaning process can be facilitated. This improves the production yield and the cleaning effects. Holes for connecting the accommodating section to the outside may be provided at corners of the accommodating section. Gas may be guided from the lower side of the accommodating section, so that heat can be efficiently applied to the semiconductor devices and bonding failures therebetween can be reduced. Further, grooves connecting adjacent holes may be provided for accommodating sections adjacent to each other.

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.

Apparatus and method for manufacturing a semiconductor device

A carrier structure for fabricating a stacked-type semiconductor device includes: a lower carrier that has laminated thin plates and has first openings for mounting first semiconductor packages thereon; and an upper carrier having second openings for mounting second semiconductor packages on the first semiconductor packages. The lower carrier composed of the laminated thin plates realizes an even plate thickness and reduces warps because stress is distributed to the thin plates. This results in an improved production yield. A pattern of the openings in the thin plates of the lower carrier may be formed by etching or electric discharging. The openings thus formed have reduced warps and burrs.
