PROBLEM TO BE SOLVED: To test individual dies before mounted onto a PCB (printed circuit board), and to conduct a test up to burn-in when possible. SOLUTION: This carrier for storing the dies divided individually (bare chips) for the test and/or the burn-in, and for connecting electrically them is provided with the first contact parts arranged lattice-likely to correspond to the dies. The present invention provides the carrier capable of bringing the dies divided individually into precisely mechanical and electrical contact to execute the function test and the burn-in by an existing device. The dies sucked to an elastic bulged part by prescribed force generated by an evacuation device are brought into contact with the first contact parts of the carrier provided with the elastic bulged part. Each of the first contact part is provided with the second contact part in its tip. Each of the second contact part is connected electrically to the each first contact part.

Abstract:
The invention relates to a method for producing an electronic component, especially a memory chip, using a laser-induced correction to equalise an integrated circuit by means of at least one laser via (15) in a layer at least partially covering the circuit. Said component comprises a rewiring of the contact pads. The inventive method comprises the following steps: each laser via is closed by means of a separate covering layer (16) which is to be applied locally; a rewiring extending between the local covering layers (16) is created; the local covering layers (16) are removed; and the laser-induced correction is carried out by means of the open laser vias.

The invention relates to a semiconductor element, comprising a semiconductor chip which has at least one contact pad on a first main side and a protective layer which does not cover the at least one contact pad. The semiconductor element can be connected to a substrate by means of flip-chip contacting. Bumps are provided on the first main side, said bumps being at least partially connected to the at least one contact pad by printed conductors provided on the protective layer. The raised parts can be produced either with printable materials or by multiple galvanisation of the printed conductor ends lying opposite the contact pads.
Abstract:
The method involves immersing a transfer plate (10) in a material bath, in which a material is placed in a fluid condition, where the pressure acts at the bath and another pressure dominates in blind holes (100). A pressure difference is made between the pressures at the bath and in the holes, respectively, such that the holes are partially filled with the fluid material. The transfer plate is extracted from the bath. The transfer plate opposite to the target plate is positioned, where the material is casted out from the holes to contact with the target plate and to place at the target plate. An independent claim is also included for a device for executing a method for placing material.
