A three-dimensional semiconductor integrated circuit device is provided. A first semiconductor chip includes a solid-state circuit and is smaller than a base, and is stacked on the base. The first chip is buried by a first filling material having approximately the same contour as the base. Buried electrodes that penetrate through the first chip along its thickness direction are formed in the first chip. A second semiconductor chip includes a solid-state circuit and is smaller than the base, and is stacked on the first chip. The second chip is buried by a second filling material having approximately the same contour as the base. Buried electrodes that penetrate through the second chip along its thickness direction are formed in the second chip. The first and second filling materials have processibilities required for forming the buried electrodes and thermal expansion coefficients equivalent to those of the first and second chips, respectively.

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.

In a framed lead assembly for a semiconductor element, conductive lead strips comprising inward end portions for connection to electrode areas of the semiconductor element are supported to a frame by reinforcing strips of an insulating material made integral with at least center portions of the respective lead strips and a connection arrangement connecting the reinforcing strips with the frame. The connection arrangement may comprise those outward end regions of the respective reinforcing strips which are made integral with the frame of the insulating material and those outward end areas of the respective lead strips which are attached to the frame. The reinforcing strips may be connected together by bridge members of either the insulating material or another insulating material. Alternatively, the connection arrangement may comprise bridge members connecting the reinforcing strips together and supporting members connecting the bridge members with the frame with outward end portions of the lead strips either separated from the frame or having outward end areas extended further outwardly of the respective outward end portions and attached to the frame. Preferably, the frame and the bridge and supporting members are of the insulating material and made integral with one another with the outward end portions being not made integral with the reinforcing strips. Also preferably, the inward end portions are not made integral with the reinforcing strips in whichever structure of the connection arrangement.

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.

A first bump is arranged on an electrode of a semiconductor chip. An opening portion formed at a position corresponding to an electrode on the semiconductor chip, a conductive lead subjected to patterning and arranged in the opening portion, and a second bump for being connected to the outside of the device are formed on a flexible substrate, and the conductive lead and the first bump are connected to each other in the opening portion. An external shape of the flexible substrate is approximately the same as that of the semiconductor chip.

Solder balls are attached to a flexible printed-circuit board which is shaped so as to be able to cover at least an upper surface, a side surface, and a lower surface of an IC chip, and the flexible printed-circuit board is placed on the IC chip. Then, the flexible printed-circuit board is folded over edges of the IC chip, and bonded to outer surfaces of the IC chip by an adhesive sheet. Thereafter, a sealing resin is poured into a gap between the upper surface of the IC chip and the flexible printed-circuit board, and cured, thereby completing a semiconductor package.
