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.

Принадлежит: Adhesives Research Inc

Pressure sensitive adhesives for use primarily in medical applications are disclosed. The pressure sensitive adhesives are urethane elastomeric adhesives that include a polyurethane polymer and a compatible tackifier and/or compatible plasticizer to achieve an adhesive having a predetermined compliance. The result is a pressure sensitive adhesive for application to skin that can eventually be removed with very little trauma to the skin and with a low pain rating, but which still exhibits very good peel strength when used to construct an article in which the adhesive is adhered to human skin.

In a wafer processing tape, circular or tongue-shaped notched parts facing the center of an adhesive layer, as seen in a plan view, are formed so as to correspond to a pasting region to a wafer ring to a depth that reaches a release substrate from the side of a base material film. Due to the formation of the notched parts, when a peeling force acts on the wafer processing tape, portions of a tacky material layer and the base material film which are more outward than the notched parts are peeled off first, and a portion that is more inward than the notched parts remains on the wafer ring in a protruding state. Accordingly, a peeling strength between the wafer processing tape and the wafer ring can be increased and the wafer processing tape can be suppressed from being peeled off from the wafer ring during processes.

The present invention relates to a hot-melt adhesive resin film having an excellent adhesive force and durability to various adherends such as metal, glass, and plastic, and a production method thereof. More particularly, the present invention relates to a hot-melt adhesive resin film including a first surface layer, a first intermediate layer, a substrate layer having heat resistance, a second intermediate layer, and a second surface layer, which are laminated in this order, in which the first intermediate layer and the second intermediate layer include a resin which is obtained by modifying a copolymer of propylene and 1-butene with maleic acid, and a production method thereof. 1. A hot-melt adhesive resin film comprising a first surface layer , a first intermediate layer , a substrate layer having heat resistance , a second intermediate layer , and a second surface layer , which are laminated in this order ,wherein said first intermediate layer and said second intermediate layer include a resin which is obtained by modifying a copolymer of propylene and 1-butene with maleic acid.2. The hot-melt adhesive resin film according to claim 1 , wherein said first surface layer and said second surface layer include a composition having an acid-modified polyolefin and an epoxy group-containing resin or a composition having an acid-modified polyolefin and an oxazoline-group containing resin.3. The hot-melt adhesive resin film according to claim 1 , wherein said first surface layer and said second surface layer contain 80 parts by mass to 99.9 parts by mass of an acid-modified polyolefin resin (A) claim 1 , and 0.1 parts by mass to 20 parts by mass of an epoxy group-containing polyolefin-based resin (B) having a main chain which is obtained by copolymerizing an olefin compound and an epoxy group-containing vinyl monomer and a side chain bound to said main chain claim 1 , and having a melting point of 80° C. to 120° C.4. The hot-melt adhesive resin film according to claim 1 , ...
