Adhesive sheet and method of backgrinding semiconductor wafer

Номер: US20120052772A1

Автор: Masashi Kume, Tomomichi Takatsu

Принадлежит: Denki Kagaku Kogyo KK

After an adhesive sheet is pasted on a semiconductor wafer, an adhesive of the sheet increases tight attachment to the semiconductor wafer because wetting spreads over time. Due to this, at the time of peeling the adhesive sheet from the ground semiconductor wafer, the semiconductor wafer used to be damaged. This phenomenon is likely to occur for a thinner semiconductor wafer. The present invention resides in an adhesive sheet including a substrate and an adhesive layer disposed on the substrate. The substrate is formed of an ethylene/vinyl acetate copolymer having a vinyl acetate content of 10% by mass or less. The adhesive layer contains 100 parts by mass of a (meth)acrylate ester copolymer, 1 to 10 parts by mass of a cross-linker, 0.05 to 5 parts by mass of a silicone compound. The (meth)acrylate ester copolymer is formed of a copolymer produced by polymerizing a (meth)acrylate ester monomer and a functional-group-containing monomer.

A method of forming an adhesive bond between a first substrate and a second substrate includes applying a semi-crystalline polymeric adhesive composition to a bonding area of the first substrate, and, after applying, disposing the second substrate adjacent to and in contact with the composition to form a workpiece. After disposing, the method includes heating the workpiece to cure the composition and thereby form a thermoset polymeric adhesive material that is crosslinked. After heating, the method includes cooling the workpiece such that the material has a crystalline molecular structure. Concurrent to cooling, the method includes imposing a stress on the material to thereby orient the crystalline molecular structure in a desired direction, and, after imposing, dissipating the stress along the crystalline molecular structure in the desired direction to thereby form the adhesive bond between the first substrate and the second substrate.

Since loss of the applied voltage is minimized and the charged particles are freely driven, driving performance of the display device is excellent although a high voltage is not applied in driving a flexible display device, such as a flexible LED, an organic electro luminescence (EL) element including an electronic paper, and the like.
