Semiconductor device and method of manufacturing the same
View Patent ↗A semiconductor package is provided with a low thermal conductivity plate that covers an entire upper surface of a heat dissipating component, by which heat dissipation from the heat dissipating component can be inhibited during a reflow process. Accordingly, sufficient heat can be transmitted to solder balls, so as to heat the solder balls up to a desired temperature. As a result, the semiconductor package and a substrate can be fully bonded via the solder balls, and thereby an excellent mounting performance is achieved.
1. A method of manufacturing a semiconductor device including a semiconductor substrate on which an elements layer and a heat dissipating component are formed, comprising:
forming a heat dissipation preventing component on said heat dissipating component with an adhesive before mounting said semiconductor device on a base material; and
removing said heat dissipation preventing component from said heat dissipating component after mounting said semiconductor device on said base material,
wherein the heat dissipation preventing component is formed on said heat dissipating component with an adhesive before mounting said semiconductor device on a base material such that the heat dissipation preventing component inhibits heat dissipation from the heat dissipation component when it receives heat during the mounting of said semiconductor device on said base material.
2. A method of manufacturing a semiconductor device including a semiconductor substrate formed on an elements formed layer and a heat dissipating component formed over said semiconductor substrate, comprising:
