    Abstract: A radio-frequency power component and a radio-frequency power module, as well as to methods for producing them are encompassed. The radio-frequency power component has a semiconductor chip that is suitable for flip chip mounting. The semiconductor chip has an active upper face that produces power losses. This active upper face is covered by an electrically isolating layer leaving free contact surfaces, with a heat-dissipating metal layer being applied to its upper face. The metal layer directly dissipates the heat losses from the active semiconductor structures.

    Abstract: In a semiconductor (SC) component comprising a housing (1) and an SC chip (2) with flip-chip contacts (3) arranged on its active upper side (4) and located on contact connecting surfaces (5) of the upper side (6) of a wiring substrate (7), the underside (8) of which has external contact surfaces with external contacts (9) of the SC component (10), in electrical contact with surfaces (5), the reverse side (11) of the chip has a flat pattern (12) with boundary edges (13) in a predetermined geometric orientation relative to the arrangement of flip-chip contacts on the active upper side. An independent claim is included for the production of the SC components by: producing an SC wafer with SC chip positions, integrated circuits and contact surfaces for flip-chip contacts (3) in a predetermined arrangement on its active side (4); applying the flat pattern (12) to the reverse side (11) of the wafer in the SC chip positions; applying the flip-chip contacts to the contact surfaces in the SC chip positions; separating the wafer into SC chips (2) with flip-chip contacts; preparing a wiring substrate (7) with SC component positions and appropriately arranged contact connection surfaces (5); applying the chips to the wiring substrate in the SC component positions, while orienting the flip-chip contacts (3) relative to the contact connection surfaces (5) utilizing the flat pattern (12); bonding the flip-chip contacts to the contact connection surfaces; and packing the SC component positions in a plastics housing mass (17), while embedding the SC chips (2).

    Abstract: The invention relates to a device and a method for the placement of electronic components (4) on transport belts, whereby a mould support (1) comprises at least one recess (2), over which a planar plastic web (5) is arranged. A heater (6, 7) heats the mould support (1) and/or the plastic web (5) in the region of the recesses (2). A stamping tool (8), comprising the electronic component (4) in the stamping region (9) thereof, is stamped, with the electronic component (4) in the direction of the recess (2) of the mould support (1), into the plastic web (5) to form a belt pocket (3).

    Abstract: An apparatus for singulating and bonding semiconductor chips includes a singulating station and a mounting station. In the singulating station, a semiconductor chip is provided with a bonding wire by a bonding tool and lifted off a carrier film. Then, in the mounting station, the semiconductor chip is placed on a chip mounting surface and fixed in place. The bonding wire is guided to a contact-connection surface of the circuit carrier and bonded to this surface.

    Abstract: Eine Vorrichtung zum Steuern einer Bewegung einer Schleifscheibe eines Halbleiterwafer-Schleifsystems umfasst zumindest eine Schnittstelle, die ausgebildet ist, um ein Feedbacksignal zu erhalten, umfassend Schleifkraftinformation, die eine Kraft anzeigt, die auf einen Halbleiterwafer durch die Schleifscheibe ausgeübt wird. Die Vorrichtung umfasst ferner ein Steuerungsmodul, das ausgebildet ist, um ein Steuerungssignal zum Steuern der Bewegung der Schleifscheibe basierend auf der Schleifkraftinformation zu erzeugen. Das Steuerungsmodul ist ausgebildet, um das Steuerungssignal zu erzeugen, um eine Vorwärtsbewegung der Schleifscheibe gemäß einem gewünschten Geschwindigkeitsprofil während des Schleifens des Halbleiterwafers auszulösen, wenn die Schleifkraftinformation anzeigt, dass eine Kraft, die durch die Schleifscheibe ausgeübt wird, unter einer Kraftschwelle ist. Das Steuerungsmodul ist ausgebildet, um das Steuerungssignal zu erzeugen, um eine Bewegung der Schleifscheibe zu erzeugen, die langsamer ist als das gewünschte Geschwindigkeitsprofil während des Schleifens des Halbleiterwafers, wenn die Schleifkraftinformation anzeigt, dass die Kraft, die durch die Schleifscheibe ausgeübt wird, über der Kraftschwelle ist. Die zumindest eine Schnittstelle ist ausgebildet, um das Steuerungssignal zum Steuern einer Bewegung der Schleifscheibe bereitzustellen.

    Abstract: An apparatus and a method for populating transport tapes with electronic components includes a mold support having at least one recess over which a flat plastic strip is disposed. A heater heats the mold support and/or the plastic strip in an area of the recesses. An embossing tool, which has the electronic component in its embossing area, together with the electronic component, is embossed into the plastic strip in the direction of the recess into the mold support to form a tape pocket.
