Abstract

The invention relates to a black composite particles for semiconductor sealing material and a semiconductor sealing material using the same. Black composite particles for semiconductor sealing material, comprise: an extender pigment as a core particle; and a black pigment provided on the surface of the extender pigment in an amount of 1 to 100 parts by weight per 100 parts by weight of the extender pigment. Such black composite particles not only exhibit enhanced blackness, moisture resistance, fluidity and tinting strength but also show an excellent dispersibility in binder resins. The resulting semiconductor sealing material is capable of exhibiting a high volume resistivity as well as excellent blackness, moisture resistance, soldering heat resistance, flowability and flexural strength.

Description

Technical field [0001] The present invention relates to black composite particles for semiconductor sealing materials and semiconductor sealing materials, in particular to black composite particles for semiconductor sealing materials with high blackness, moisture resistance, fluidity and coloring power, and good dispersibility to binder resin. And using the black composite particles, a semiconductor sealing material with high volume resistivity, blackness, moisture resistance, solder heat resistance, flowability, and flexural strength. Background technique [0002] At present, in order to physically and chemically protect electronic components such as ICs, LSIs, transistors, semiconductor switching elements, and diodes, while fixing these components, it is necessary to seal them with thermosetting resin. [0003] In recent years, with the increase in the size of plastic packages used for sealing, silica particles as fillers have been added to semiconductor sealing materials in or...
