ABSTRACT:
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.
