摘要:
An adhesive composition for semiconductors, an adhesive film prepared using the adhesive composition, and a semiconductor device including the adhesive film, the adhesive composition exhibiting two exothermic peaks at temperatures ranging from 65° C. to 350° C., wherein a first exothermic peak appears at a lower temperature than a second exothermic peak, and the adhesive composition has a curing rate of about 70% to 100% in a first exothermic peak zone, as calculated by Equation 1: Curing rate=[(Heating value upon 0 cycle−Heating value after 1 cycle)/Heating value upon 0 cycle]×100.
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.

A pressure sensitive dicing die bonding film includes a base film, a pressure sensitive adhesive layer formed on the base film, and a bonding layer formed on the pressure sensitive adhesive layer. An adhesive strength between the pressure sensitive adhesive layer and the bonding layer and an adhesive strength between the pressure sensitive adhesive layer and a ring frame may satisfy the following relation: B/A≧1.1 where A is the adhesive strength between the pressure sensitive adhesive layer and the bonding layer, and B is the adhesive strength between the pressure sensitive adhesive layer and the ring frame.

Disclosed is an apparatus for removing a thermal sleeve from a cold leg of a reactor coolant system, which removes an unintentionally separated thermal sleeve without pipe cutting, preventing invasion of impurities into pipes and achieving reliable pipe re-welding. The apparatus includes a sleeve removal tool including a corn head formed at a shaft, a pressure plate below the corn head to maximize hydraulic pressure inside a safety injection pipe, a spring connected to the pressure plate to keep the pressure plate unfolded, and a guide wheel to guide the sleeve removal tool into the safety injection pipe, a horizontal movement carrier including bodies connected to each other by a link, a seating rod for seating of the sleeve removal tool, and moving wheels for movement of the horizontal movement carrier, and a vertical movement carrier including first and second anti-separation bars to prevent separation of the horizontal movement carrier.
