Abstract

See full text

A method of manufacturing a semiconductor device includes mounting a first semiconductor element on a first surface of a base plate, wherein solder balls are formed on a second opposite surface of the base plate such that the second opposite surface includes an area without solder balls. At least one second semiconductor element is mounted to the base plate at the area of the second surface without solder balls. The at least one semiconductor element may be mounted to the base plate using low molecular adhesive, or in the alternative, high temperature solder.
