Embodiment

[0056] Examples and comparative examples of the present invention will be described below. However, the present invention should not be construed as being limited to these Examples. Incidentally, "parts" and "%" in the examples are defined as "parts by weight" and "% by weight", respectively, unless otherwise specified.

[0057] First, before preparing a thermosetting resin composition, a partially allyl etherified phenolic resin was synthesized (Synthesis Examples A-1 to A-4).

Synthetic example A-1

[0059]Phenolic resin (GS-180, manufactured by Qunei Chemical Industry Co., Ltd., phenol equivalent: 105g / eq.) (105 parts), 90.7 parts of allyl bromide (provided by Tokyo Chemical Industry Co., Ltd., Ltd.), 138.2 parts of potassium carbonate (manufactured by Wako Pure Chemical Industries, Ltd.) and 500 parts of acetone (manufactured by Wako Pure Chemical Industries, Ltd.) were mixed and mixed in a nitrogen stream Reflux for 24 hours with heating. After cooling to room temperature (25° C.), filtration and concentration were performed, and 400 parts of ethyl acetate (manufactured by Wako Pure Chemical Industries, Ltd.) was added to the residue, followed by 200 parts of a 5% hydrochloric acid solution diluted with distilled water (manufactured by Wako Pure Chemical Industries, Ltd.) was washed once, and washed twice with 200 parts of distilled water. Thereafter, the organic layer was extracted and dried over magnesium sulfate (manufactured by Wako Pure Chemical Industries, Ltd.),...

Synthetic example A-2

[0061] Phenolic resin (GS-180, manufactured by Qunei Chemical Industry Co., Ltd., phenol equivalent: 105 g / eq.) (105 parts), 60.5 parts of allyl bromide (manufactured by Tokyo Chemical Industry Co., Ltd.), 103.7 parts of potassium carbonate (manufactured by Wako Pure Chemical Industries, Ltd.) and 500 parts of acetone (manufactured by Wako Pure Chemical Industries, Ltd.) were mixed, and refluxed under heating in a nitrogen stream for 24 hours. After cooling to room temperature (25° C.), filtration and concentration were performed, and 400 parts of ethyl acetate (manufactured by Wako Pure Chemical Industries, Ltd.) was added to the residue, followed by 200 parts of a 5% hydrochloric acid solution diluted with distilled water (manufactured by Wako Pure Chemical Industries, Ltd.) was washed once, and washed twice with 200 parts of distilled water. Thereafter, the organic layer was extracted and dried with magnesium sulfate (manufactured by Wako Pure Chemical Industries, Ltd.), fo...

Abstract

The present invention relates to a method for producing a cured product of a thermosetting resin composition and a cured product obtained thereby. The method includes: heating a thermosetting resin composition including the following ingredients (A) to (C) at a temperature of 100 to 200 DEG C for 1 to 60 minutes; and then further heating the thermosetting resin composition at a temperature of 220 to 350 DEG C for 10 to 6,000 minutes, thereby curing the thermosetting resin composition: (A) an allyletherified phenol resin; (B) an epoxy resin; and (C) a curing accelerator.

Description

technical field [0001] The present invention relates to a method for producing a cured product of a thermosetting resin composition used for encapsulation materials requiring high heat resistance in power devices and the like, and a cured product obtained thereby Excellent in heat resistance and heat cycle resistance. Background technique [0002] Generally, semiconductor devices have heretofore been manufactured by packaging semiconductor elements such as transistors, ICs, and LSIs with ceramic packages, plastic packages, and the like. The former ceramic packages have excellent durability under high temperature and high humidity because their constituent materials themselves have heat resistance and also have excellent moisture resistance, and additionally have excellent mechanical strength. Therefore, highly reliable packaging is possible. However, the above ceramic package has problems that the constituent materials are relatively expensive and the mass yield of the pac...
