    摘要: An epoxy resin composition comprising: (A) an epoxy resin having at least three epoxy groups per molecule and an epoxy equivalent of 170 or lower; (B) an epoxy resin having a phenolic nucleus and two epoxy groups in such an amount that a weight ratio of the epoxy resin (B) to the epoxy resin (A) ranges from 35/65 to 65/35; (C) a phenolic curing agent in such an amount that a molar ratio of phenolic hydroxyl groups to the whole epoxy groups in the composition ranges from 0.5 to 1.5; and (D) an inorganic filler in an amount of from 86 to 92 wt %, based on a total weight of the composition. The composition provides encapsulated semiconductor devices much less warped than those encapsulated with a conventional composition.

    摘要: An epoxy resin composition is provided comprising (A) an epoxy resin, (B) a phenolic resin curing agent, (C) an inorganic filler, (D) a cure accelerator, (E) an adhesion promoter, and (F) a metal oxide. The metal oxide (F) is a combination of a magnesium/aluminum ion exchanger, a hydrotalcite ion exchanger, and a rare earth oxide in a ratio of 0.5-20:0.5-20:0.01-10 pbw, relative to 100 pbw of epoxy resin (A) and curing agent (B) combined.

    摘要: When a second detector determines that a character image has a halftone (YES in #1) and a third detector (48) determines that a font size of the character image is equal to or greater than a threshold value β and equal to or smaller than a threshold value α (YES in step #4), a fourth detector determines whether a presently focused pixel constitutes a particular portion of a character (step #5). When the fourth detector determines that the pixel data of the presently focused pixel constitutes the particular portion of the character (YES in step #5), the image processing section sets the pixel data to be subjected to a second screen processing which is performed at a higher gradation level (step #6).
