    摘要: This invention provides a semiconductor device lead frame comprising a mounting tab for a semiconductor chip located within the lead frame and multiple inner leads extending to the area adjacent to the perimeter of the tab. The configuration of the inner leads with respect to one another and the mounting tab is stabilized by adhering at least a portion of the leads and, optionally, the mounting tab to a dielectric film coated on one side with a cured, heat-activated silicone adhesive.

    摘要: A low modulus silicone rubber which cures at room temperature can be obtained by exposing a composition made from a hydroxyl endblocked polydiorganosiloxane, an aminoxy silicon compound having two aminoxy groups per molecule, such as, methylvinyldi-(N,N-diethylaminoxy)silane, and a hydrolyzable organosilicon compound which has at least three hydrolyzable groups per molecule including oxime, alkoxy, amino, vinyloxy, amide, imide, and lactam such as methyltri(N-methylacetamido)silane or methyltrimethoxysilane. The compositions can be packaged in a single container and, if sealed, remain stable until exposed to moisture. The compositions can be made by a two-step method comprising mixing the aminoxy silicon compound and the hydroxyl endblocked polydiorganosiloxane and thereafter blending in the hydrolyzable organosilicon compound.
