2. Description of the Related Art In recent years, plastic-sealed semiconductor devices such as ICs and LSIs have become increasingly difficult to dissipate not only heat from a lead frame but also heat dissipation called a heat sink or a heat spreader in a plastic package due to an increase in heat generation capacity of a chip. Although excellent metals are inserted into the package, there are problems such as a complicated manufacturing process and a high cost of a heat sink and a heat spreader. On the other hand, enhance the thermal conductivity of the resin composition itself,
Attempts have been made to remove the heat sink and heat spreader, but this has been a problem due to poor moldability and reduced soldering heat resistance.

As nitrogen-containing inorganic compounds, SiN (silicon nitride), AlN (aluminum nitride), BN (boron nitride)
And the like, but are not limited thereto. Further, in order to enhance the chemical stability of the nitrogen-containing inorganic compound, it is more preferable to coat the nitrogen-containing inorganic compound with fused silica. The nitrogen-containing inorganic compound in the inorganic filler is preferably 80 to 98% by weight. If it is less than 80% by weight, thermal conductivity is undesirably reduced. The coating with fused silica is 1
A coating having a thickness of not more than μm is preferred for enhancing the chemical stability without impairing the thermal conductivity. The chemical stability means that, for example, when a nitrogen-containing inorganic compound is treated under high temperature and high humidity, it is hydrolyzed to generate ammonia and the like, but it means to suppress these phenomena.
