Abstract: Integrated circuit dies are mounted to the interconnection leads on frames of tape automatic bonding (TAB) film. Thereafter, each frame of the TAB film with the attached integrated circuit die is affixed to an electrically insulating, thermally conductive plate to form a sandwich structure. A number of sandwich structures are bonded together to form a stack of sandwiches. The interconnection leads of each sandwich in the stack are selectively electrically connected to the interconnection leads of other sandwiches in the stack to form a system of electrically interconnected integrated circuits. The system is compact and has short interconnection paths between integrated circuits so that the propagation delays of signals between integrated circuits are minimized.

Abstract: An optical section of an intraocular lens has a pair of spaced apart threaded recesses which are threadingly locked to threaded shank sections of an iris retention loop. The shank sections are integrally joined to such loop so each shank section acts as an anchor preventing a screwing movement of the other shank relative to the optical section. A method is described of expanding a shank section of a lens retention member in situ within a threaded or other undercut recess of an optical section of an intraocular lens.

Abstract: An intraocular lens with an iris retention loop that is attached to an optical section of the lens by a pair of shank sections. Each shank section has a noncircular cross sectional area to provide a more flattened contact surface for engaging an inner edge of the iris. Such structure reduces cutting of the iris when the iris is stretched over these shank sections to retain the lens in the eye.
