    摘要: 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.

    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.
