Abstract:
A film removal method and apparatus for removing a film from a substrate are disclosed. The method comprises the steps of disposing a plasma generator and a sucking apparatus over the substrate, projecting a plasma beam from the plasma generator onto the film obliquely, disposing the sucking apparatus on a reflection path of plasma projected by the plasma generator, and sucking a by-product of an incomplete plasma reaction occurring to the film so as to keep a surface of the substrate clean, with a view to overcoming the drawbacks of deposition of the by-product which results from using the plasma as a surface cleansing means under atmospheric conditions.

Abstract:
A semiconductor packaging process comprising following steps is provided. First, a wiring substrate with a first surface and a second surface is provided. Next, a non-solvent type two-stage thermosetting compound is formed on the first surface of the wiring substrate. The non-solvent type two-stage thermosetting compound is then partially-cured such that a non-solvent type B-stage adhesive layer is formed on the first surface of the wiring substrate to provide a carrier for semiconductor packages. Thereafter, a chip is attached on the first surface of the wiring substrate via the B-stage adhesive layer. Ultimately, the chip is electrically connected to the wiring substrate and an encapsulating material is then formed to seal the chip. A carrier for semiconductor packages used the above mentioned packaging process is also provided.

A method and system for motion estimation using chrominance information, which is based on each block of a current frame to find a corresponding block from a previous frame within a search area and accordingly determines a motion vector and includes first separately computing luminance differences and chrominance differences between luminance and chrominance of a target block in a current frame and luminance and chrominance of candidate blocks in a search range of a previous frame, next adjusting the luminance differences based on the first chrominance differences and the second chrominance differences and outputting adjusted luminance differences; and finally finding a minimum one among the adjusted luminance differences and accordingly determining the motion vector.
Abstract:
A method for the improved electroplating of copper on to a copper seed layer provides treating the surface of a copper seed layer with nitrogen or another anaerobic gas. In another aspect, a burnishing treatment is used to enhance the platability of the copper seed layer. According to another aspect, the seed layer is annealed either at an elevated temperature or for an extended time at room temperature. According to another aspect, the seed layer surface is exposed to a chemical solution that includes a surfactant, chemicals that dissolve contaminants, or both. In another aspect, the deposition of the copper seed layer may be tailored to produce a surface morphology more suited to electroplating. Following the treatment of the seed layer, the copper layer that is electroplated onto the seed layer exhibits improved quality.
