Latest Patents

One of his latest patents is titled "System and method for substrate transport." This invention introduces substrates into a vacuum environment by gradually reducing the number of substrates being transferred simultaneously as the clean and evacuated environment is progressed. Cassettes are maintained in a clean atmospheric environment and do not enter the vacuum environment. Several vacuum locks are linearly staggered to introduce progressively higher levels of vacuum. The number of substrates transported through this arrangement is a portion of the number of substrates present in each cassette. The staggered vacuum locks lead to a series of processing chambers, wherein a yet smaller number of substrates, such as one or two, are transported.

Another significant patent is "Method and apparatus for molding with reduced cull formation." This invention provides an apparatus and process for molding electronic devices in a mold. The apparatus comprises at least one runner in the mold connected to a mold supply pot for channeling a molding compound from the mold supply pot to the electronic devices. A plunger assembly is included, which comprises a main body and a supplementary body configured to be movable relative to the main body. The plunger assembly is locatable in the mold supply pot and is drivable towards the runner for forcing the molding compound into the runner. To avoid or reduce cull formation, the width of the runner at the opening connecting the runner to the mold supply pot is smaller than the width of the main body of the plunger assembly.
