摘要:
A smart-card module is described which has a substrate film of an anisotropically conductive material and at least one semiconductor chip. The semiconductor chip has connection points. On one surface of the semiconductor film, contact areas are applied directly. The substrate film is disposed between the semiconductor chip and the contact areas in such a way that it connects the connection points of the semiconductor chip to the contact areas in a manner of a direct contact.

The invention relates to an adhesive joint which connects a body made of a first material to a plastic body. The adhesive joint is formed by an adhesive laminate which includes a flexible core layer made of acrylate and outer layers made of hot-melt adhesive which respectively adjoin the first body and the plastic body, and a transition layer is respectively arranged between the outer layers and the core layer.
摘要:
A smart card is laminated from at least two layers of paper or film as a mounting material. A first of the layers is fitted with a semiconductor chip and a second layer has connecting contacts as well as conductor tracks or external connecting surfaces. The contacts of the semiconductor chips are electrically conductively connected to the connecting contacts on the second layer. No chip modules are required to produce the smart cards. The mounting materials provided with ICs and contacts can be laminated in an endless roll format, in the same way as for paper production.
摘要:
A method for producing a chip module includes punching a chip carrier to form a chip carrier fixing section and chip carrier contact sections spaced apart from the chip carrier fixing section by slots defining a given distance. The given distance is subsequently reduced to a dimension preventing a flow through of a sealing mass by a swaging operation carried out at least in a region close to the slots.
摘要:
Flip-chip bumps (solder bumps) are applied on the contact-connection points of a semiconductor chip. These bumps extend from there through a covering compound (mold) that is applied as a protective layer. The end of each one of the bumps that is remote from the semiconductor chip forms a pad. This pad lies approximately plane-parallel in the surface of the covering compound that is remote from the semiconductor chip. At least during the encapsulation process, the chips are preferably arranged on a carrier element, in particular a carrier strip.

An optoelectronic component includes a substrate, on which a semiconductor chip and a wettable attractor element are arranged. A medium including pigments at least regionally covers the exposed region of the substrate that is not covered by the semiconductor chip and the attractor element. The medium at least partly wets the semiconductor chip and the attractor element.
摘要:
A semiconductor component includes at least one optoelectronic semiconductor chip and a connecting carrier having a connecting surface on which the semiconductor chip is disposed. A reflective coating and a limiting structure are formed on the connecting carrier. The limiting structure at least partially encloses the semiconductor chip in the lateral direction, and the reflective coating at least partially extends in the lateral direction between a side surface of the semiconductor chip and the limiting structure.
摘要:
A semiconductor arrangement having at least one semiconductor chip, which has, on one surface, an integrated circuit and at least one contact element which is electrically conductively connected to the latter, and having an edge protector, which at least partially covers an edge region on the surface of the semiconductor, the edge region extending along outer edges of the semiconductor chip. A method for manufacturing the above-mentioned semiconductor arrangement.
摘要:
A chip card having a chip card body, a semiconductor chip and a carrier substrate, the carrier substrate being provided on both sides with surface contacts and with contact-hole lines electrically connecting the upper and lower surface contacts to one another. The contact-hole lines are arranged so close to the edge of the carrier substrate that their lower ends open out into a base of an outer cavity, where they are closed off, to thereby prevent moisture from penetrating into the inner cavity, in which the semiconductor chip is located, without it being necessary to produce a dedicated cover for the contact-hole lines.
