Title: Method for dicing semiconductor wafer
Inventor: SAIDA SEIJI
IPC: H01L21/301
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To reduce blinding of a rotary blade for dicing for improved tipping characteristics, by irradiating with ultraviolet ray between a pasting process where an ultraviolet ray setting type adhesive agent laminated on a sheet is pasted to a semiconductor wafer and a dicing process where the semiconductor wafer is diced. SOLUTION: An ultraviolet ray is irradiated between a pasting process where an ultraviolet ray setting type adhesive agent laminated on a sheet is pasted to a semiconductor wafer and a dicing process where the semiconductor wafer pasted to a sheet is diced. The ultraviolet ray irradiation process is provided between the pasting process and the dicing process so that both degradation in adhesive force and improvement in cohesive force of the ultraviolet ray setting type adhesive agent are promoted. Relating to a base material of the ultraviolet ray setting type adhesive agent and the action when an ultraviolet ray is irradiated, a base polymer which is a main agent exhibits adhesive force, while an ultraviolet ray polymerization triggering agent under ultraviolet ray makes oligomer and/or monomer into 3 dimensional mesh structure for setting (an adhesive force is degraded).

Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To additionally suppress the elution from a blood contact surface, to more prolong the development time of an antithrombotic effect and to increase the hydrophilicity of the bloodstream contact surface so as to facilitate priming by subjecting the composite of a quaternary ammonium salt and antithrombotic mucopolysaccharide applied on the bloodstream contact area to an irradiation treatment with UV rays. SOLUTION: The bloodstream contact medical member is formed by subjecting the composite of the quaternary ammonium salt and at least one kind of the antithrombotic mucopolysaccharide applied on the blood flow contact area to the irradiation treatment with the UV ray. As a result, the elution of the mucopolysaccharide from the bloodstream contact area is additionally suppressed and not only the development time of the antithrombotic effect may be more prolonged but the hydrophilicity of the bloodstream contact area may be achieved.  The success in the additional suppression of the elution of the antithrombotic mucopolysacharide and the additional prolonging of the development time of the antithrombotic effect is estimated to be resulted from the formation of the crosslinking bonding between the complex and the base material and between the complexes and is estimated to be based on the introduction of the hydrophilic group to the bloodstream contact area by the UV irradiation.
