  • Patent number: 8440504
    Abstract: The present invention is related to a method for aligning and bonding a first element (1) and a second element (2), comprising: obtaining a first element (1) having at least one protrusion, the protrusion having a base portion (12) made of a first material and an upper portion (13) made of a second, deformable material, different from the first material; obtaining a second element (2) having a first main surface and second main surface (8) and at least one through-hole between the first and second main surface; placing the first and second element onto each other; receiving in the through-hole of the second element (2) the protrusion of the first element (1), the protrusion being arranged and constructed so as to extend from an opening of the through-hole in the first main surface to a position beyond an opening of the through-hole in the second main surface (8); deforming the deformable portion (13) of the protrusion, such that the deformed portion mechanically fixes the second element (2) on the first el

  • Patent number: 8399986
    Abstract: A method of positioning at least 2 chips simultaneously on a substrate by parallel stochastic assembly in a first liquid is disclosed. In one aspect, the chips are directed to target sites on the substrate within the first liquid. The target sites are covered with a second liquid. The second liquid and the first liquid are immiscible. The chips are attracting the first liquid. A predetermined surface is chosen or treated on each chip such that it is selectively attracted by the second liquid and attracting the first liquid.

  • Patent number: 7759701
    Abstract: The present invention is related to a method of producing a semiconductor device and the resulting device. The method is suitable in the first place for producing high power devices, such as High Electron Mobility Transistors (HEMT), in particular HEMT-devices with multiples source-gate-drain groups or multiple base bipolar transistors. According to the method, the interconnect between the source contacts is not produced by air bridge structures, but by etching vias through the semiconductor layer directly to the ohmic contacts and applying a contact layer on the backside of the device.
