Abstract: An electronic device includes an anisotropic conductive adhesive film as a connection material, wherein the anisotropic conductive adhesive film has a flowability of 50% or more after preliminary pressing at 80° C. and 1 MPa for 1 second and final pressing at 180° C. and 3 MPa for 5 seconds, and a connection resistance increment greater than 0% but not greater than 25%, as calculated by Expression 1: Connection resistance increment (%)=(A?B)/A×100??(Expression 1) where A is a connection resistance measured after preliminary pressing at 80° C. and 1 MPa for 1 second and final pressing at 180° C. and 3 MPa for 5 seconds, and B is a connection resistance measured after reliability evaluation at a temperature of 85° C. and a humidity of 85% for 250 hours following preliminary pressing and final pressing.

Abstract: A semiconductor device bonded by an anisotropic conductive adhesive composition, the anisotropic conductive adhesive composition having a solid content ratio between a polymer binder system and a curing system of about 40:60 to about 60:40, and a coefficient of thermal expansion of about 150 ppm/° C. or less at about 100° C. or less.

Abstract: The present invention relates to a method for controlling elasticity of skin and compositions for the same, and more particularly, to a method for controlling elasticity of skin comprising the step of using a compound that inhibits or induces expression of tropoelastin mRNA or protein in keratinocytes. The present invention provides compositions for maintaining elasticity of skin by controlling tropoelastin mRNA or protein within human skin. The method for controlling elasticity of skin and compositions thereof regulates tropoelastin expression in keratinocytes, maintaining elasticity of skin and inhibiting production of elastotic material.
