Apparatus to control transfer parameters during transfer of semiconductor devices
An apparatus includes a transfer mechanism to transfer an electrically-actuatable element directly from a wafer tape to a transfer location on a circuit trace on a product substrate. The transfer mechanism includes one or more transfer wires. Two or more stabilizers disposed on either side of the one or more transfer wires. A needle actuator is connected to the one or more transfer wires and the two or more stabilizers to move the one or more transfer wires and the two or more stabilizers to a die transfer position.
Micro-component anti-stiction structures
A micro-component comprises a component substrate having a first side and an opposing second side. Fenders project from the first and second sides of the component substrate and include first-side fenders extending from the first side and a second-side fender extending from the second side of the component substrate. At least two of the first-side fenders have a non-conductive surface and are disposed closer to a corner of the component substrate than to a center of the component substrate.
Method for electrically contacting a component by galvanic connection of an open-pored contact piece, and corresponding component module
The invention relates to a method for electrically contacting a component (10) (for example a power component and/or a (semiconductor) component having at least one transistor, preferably an IGBT (insulated-gate bipolar transistor)) having at least one contact (40, 50), at least one open-pored contact piece (60, 70) is galvanically (electrochemically or free of external current) connected to at least one contact (40, 50). In this way, a component module is achieved. The contact (40, 50) is preferably a flat part or has a contact surface, the largest planar extent thereof being greater than an extension of the contact (40, 50) perpendicular to said contact surface. The temperature of the galvanic connection is at most 100° C., preferably at most 60° C., advantageously at most 20° C. and ideally at most 5° C. and/or deviates from the operating temperature of the component by at most 50° C., preferably by at most 20° C., in particular by at most 10° C. and ideally by at most 5° C., preferably by at most 2° C. The component (10) can be contacted by means of the contact piece (60, 70) with a further component, a current conductor and/or a substrate (90). Preferably, a component (10) having two contacts (40, 50) on opposite sides of the component (10) is used, wherein at least one open-pored contact piece (60, 70) is galvanically connected to each contact (40, 50).
