An interior unit of a split type air-conditioning apparatus which is usually mounted on a wall of a room to be cooled and is extremely thin. The unit consists of a cabinet structure including a front panel, a middle frame and a rear plate, said front panel having an air inlet opening and an air outlet opening. Also included is a centrifugal fan, preferably a turbo fan with a plurality of backward curved blades, specially designed to adapt to the unit. The means for driving said fan are designed to be partly accommodated in the body of the turbo fan for the purpose of decreasing the depth of the unit.

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 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.
