Heat Radiation Sheet And Method For Manufacturing Of The Same

A heat radiation sheet comprising:

• a protective layer;
• a first adhesive member which is disposed on the protective layer and has one or more through holes;
• a heat radiation member which is disposed on the first adhesive member and has one or more through holes;
• and
• a second adhesive member which is disposed on the heat radiation member and comprises a base portion contacting a first surface of the heat radiation member and protrusions protruding from the base portion and inserted into the through holes of the heat radiation member and the through holes of the first adhesive member,
• wherein the first adhesive member and the second adhesive member are made of different materials
• wherein the protrusions of the second adhesive member are at least partially coupled to the protective layer.

A method of manufacturing a heat radiation sheet, the method comprising:

• preparing a carrier film, a first adhesive member disposed on a first surface of the carrier film, and a heat radiation member disposed on a first surface of the first adhesive member;
• forming one or more through holes in each of the heat radiation member and the first adhesive member;
• removing the carrier film and placing a first protective layer on a second surface of the first adhesive member;
• and
• placing a second adhesive member on the heat radiation member such that the second adhesive member contacts the first protective layer and the heat radiation member,
• wherein the second adhesive member is at least partially coupled to the first protective layer.
