摘要:
Image quality degradation due to external light irradiated to an edge section of a transparent cover of a solid-state imaging device and external light propagating in the cover is prevented with a simple structure.A glass cover 60 formed to cover the whole surface of an imaging region 26 of a solid-state imaging element 10 is constituted by a transmission section 60a corresponding to the imaging region 26, and an edge section 60b that surrounds the transmission section 60a outside the transmission section 60a. The edge section 60b of the cover 60 is selectively removed around a periphery of the edge section 60b, thereby forming a frustum-shaped part whose cross-sectional area decreases monotonously from its exit side to its incidence side in the cover 60. An optical function film 63 having an optical absorption, reflection, or scattering action is formed on an outer face of the frustum-shaped part.

摘要:
In a semiconductor package stack module, an LSI (Large Scale Integrated circuit) is mounted, via fine bumps, on a ceramic carrier substrate or a flexible carrier film on which wiring conductors are formed. After a seal resin has been injected, the chip is thinned by, e.g., grinding. A plurality of such carrier substrates or carrier films are connected to each other by bumps via through holes which are electrically connected to the wiring conductors, thereby completing a tridimensional stack module. The module achieves a miniature, thin, dense, low cost, and reliable structure without resorting to a wire bonding system or a TAB (Tape Automated Bonding) system. In addition, the module has a minimum of wiring length and a desirable electric characteristic.

A device module with a circuit chip and a print-circuit substrate on which a pattern of grooves is formed by selective etching. A liquid sealing material is in the space between the circuit chip and the surface of the substrate, fixing the circuit chip on the surface of the substrate. The circuit chip has a plurality of electrodes arranged in a first pattern, and the substrate has a plurality of connection terminals arranged in the first pattern within a chip mounting area on a surface thereof. Each of the grooves passes between two adjacent connection terminals through the chip mounting area, and both ends of each groove protrudes from the periphery of the chip mounting area. After the circuit chip is placed on the chip mounting area with the respective electrodes corresponding to the connection terminals, a liquid sealing material may be spread more easily into the space between the circuit chip and the substrate by the use of capillary action to provide a more reliable and efficient seal.
