An apparatus and a method of manufacture for a stacked-die assembly. A first die is placed on a substrate such that the backside of the die, i.e., the side opposite the side with the bond pads, is coupled to the substrate, preferably by an adhesive. Wire leads electrically couple the bond pads of the first die to contacts on the substrate. A second die is placed on the first die, and wire leads electrically couple the bond pads of the second die to contacts on the substrate. Preferably, a spacer is placed between the first die and the second die. Additional dies may be stacked on the second die.

A semiconductor device includes a housing composition and a through contact extending through the housing composition. The through contact is provided in a contact hole formed through the housing composition and having an asymmetrical funnel form with at least two opposite inner wall sides oriented substantially perpendicular to the top side of the housing and a further inner wall side inclined in such a way that the contact hole has an elongated-hole cross section at the top side of the housing. In the region of the contact pad, the contact hole has a cross section adapted to the contact pad. The through contact includes a contact-making conductor track that extends from the top side of the housing along the inclined fourth inner wall side to the contact pad.
摘要:
In order to mount a semiconductor chip on a carrier layer, consolidated filler material is applied between the semiconductor chip and the carrier layer. The filler material is sucked, under the application of a partial vacuum, from at least one edge section of the semiconductor chip to at least one other edge section of the semiconductor chip. As a result, a package is provided in which the filler material is essentially free of air inclusions.

Semiconductor components, which each include at least one semiconductor chip mounted on a common carrier substrate, are singled. The separation is effected by severing of the carrier substrate. The carrier substrate is thereby bent at least in that area of the carrier substrate which is to be severed. The severing takes place beginning from the convexly curved surface of the carrier substrate. In addition, the invention describes a singling device for separating semiconductor components.

A method for COB mounting of electronic chips on a circuit board includes contact connection of connecting wires and substantially whole-area adhesive bonding of a housing. A chip is partially adhesively bonded on a circuit board in such a way that the chip can be contact-connected and can be removed again without damage to the circuit board. Electronic tests or a burn-in process is performed on the chip. The chip, with a given functionality in a manner that is required for application of the circuit board, is fully adhesively bonding.

The invention provides DNA sequences encoding novel members of the TGF-&bgr; family of proteins. The TGF-&bgr; family comprises proteins which function as growth and/or differentiation factors and which are useful in medical applications. Accordingly, the invention also describes the isolation of the above-mentioned DNA sequences, the expression of the encoded proteins, the production of said proteins and pharmaceutical compositions containing said proteins.
摘要:
A leadframe for connection to a semiconductor chip, in particular a metal leadframe, includes a plurality of lead prongs and at least two raised lead surfaces. When a semiconductor module that includes the leadframe and a semiconductor chip is sheathed with plastic, the raised lead surfaces assure a uniform flow of a plastic composition in a mold cavity and thus prevent air from becoming trapped in a plastic package. The lead surfaces are preferably created by folding over tabs in the leadframe. The invention also relates to preliminary stages of the leadframe and to semiconductor components that contain the leadframe of the invention.
