摘要:
An adhesive composition for a semiconductor has two exothermic peaks between 65° C. and 350° C. and has an area ratio of voids of less than 10%, measured after curing at 150° C. for 10 minutes and then at 150° C. for 30 minutes, and then molding at 175° C. for 60 seconds. A first exothermic peak appears between 65° C. and 185° C. and a second exothermic peak appears between 155° C. and 350° C.
