Abstract:
A method of making an interposer having an array of contact structures for making temporary electrical contact with the leads of a chip package. The contact structures may make contact with the leads substantially as close as desired to the body of the chip package. Moreover, the contact structures can be adapted for making contact with leads having a very fine pitch. In a first embodiment, the contact structures include raised members formed over a body of the interposer. A conductive layer is formed over each of the raised members to provide a contact surface for engaging the leads of the chip package. In another embodiment, the raised members are replaced with depressions formed into the interposer. A conductive layer is formed on an inside surface of each depression to provide a contact surface for engaging the leads of the chip package. Moreover, any combination of raised members and depressions may be used.

Abstract:
A method for selectively removing metal from a metallized substrate (e.g., a metallized polymer film) and the formation of devices thereby are provided. Th method involves selectively exposing the metallized surface to a demetallizing (i.e., an oxidizing) chemical solution. The metallized layer can be selectively exposed to the demetallizing solution using a flexographic printing process wherein printing rollers are used to transfer the demetallizing solution to the metallized surface. An identification device including, for example, a holographic, retro-reflective, or other metallized material and a radio-frequency transponder are also provided. The radio-frequency transponder includes an RF chip and an antenna in electrical communication with the chip. The identification device including the holographic image allows both electronic identification through the reading or identification data stored in the chip and optical identification via the holographic image.
Abstract:
In a flat panel display device, in which a display panel 1 loosely fitted on a main surface of a chassis 4 and circuit substrates held in hook portions provided on side surfaces of the chassis are connected each other through TCP's by bending the latter TCP's, and a method for manufacturing the same device, a main slit for a rounded portion of each TCP is formed in a rounded portion of the TCP and an auxiliary sub slit is also formed adjacent to the main slit. In order to reduce the peeling force exerted on connecting/fixing portions between the TCP's and the display panel, the circuit substrate is pulled up by bending the main and sub slits and then returning the sub slit to a flat state to insert the circuit substrate into the hook portions.

Abstract:
A first substrate, a second substrate, an intermediate and a plurality of particles form a laminated structure. The first substrate has a first conjunction portion and a second conjunction portion, and the second substrate has a third conjunction portion and a fourth conjunction portion which are characterized by a first hardness. The intermediate is disposed between the first substrate and the second substrate. The particles provided with a second hardness greater than the first hardness are coated on the third conjunction portion to contact the first conjunction portion and coated on the fourth conjunction portion to contact the second conjunction portion. A height difference with reference to the base surface of the second substrate exists between the end surface of the third conjunction portion and the end surface of the fourth conjunction portion. A height difference that exists between the fourth conjunction portion and the third conjunction portion can be compensated for by the particles embedded in the fourth conjunction portion. Thus the bridging of the third conjunction portion and the first conjunction portion can be uniformly performed by the particles located between the two.
Abstract:
An anisotropic conductive film (14) and circuit elements (16) are superimposed and disposed on a substrate (10). An isotropic pressing operation is performed by a pressing mold having a flexible layer (22) on the surface to be brought into contact with the circuit elements, and simultaneously heating is performed to bond the circuit elements onto the substrate. Since the flexible layer absorbs differences in thickness of the circuit elements, the plurality of circuit elements can be pressed simultaneously. Further, since the plurality of circuit elements are simultaneously heated, it is unnecessary to consider an influence of heat on unheated adjacent circuit elements in a case where the elements are heated one by one. The isotropic pressing makes it possible to prevent the anisotropic conductive film from protruding sideways. As a result, spaces between the circuit elements can be reduced.

A semiconductor device comprises a semiconductor element mounted on a first surface of a wiring substrate, and a plurality of conductive land portions formed and exposed at a second surface of the wiring substrate which is opposite to the first surface. A plurality of solder balls are respectively joined to the plurality of conductive land portions. A plurality of reinforcement resin film portions are formed to reinforce coupling between the solder balls and the conductive land portions. Each of the reinforcement resin film portions is formed around a portion of the solder ball joining to the conductive land portion. Each of the reinforcement resin film portions being bent to form a portion along the wiring substrate and a portion along the side surface of the solder ball. The coupling between the solder balls and the conductive land portions is reinforced by elastic force of the bent portions of the reinforcement resin film portions.
