Latest Patents

One of Ken Kobayashi's latest patents is a plasma processing apparatus that includes a plasma processing chamber, a substrate support, a source RF generator, and a bias RF generator. The substrate support is positioned within the plasma processing chamber. The source RF generator is designed to generate a source RF signal, which consists of source cycles, each containing a source ON state and a source OFF state. The source ON state features at least two source power levels. Additionally, the bias RF generator is connected to the substrate support and is responsible for generating a bias RF signal that includes bias cycles corresponding to the source cycles. Each bias cycle also consists of a bias ON state and a bias OFF state, with the bias ON state having at least two bias power levels.

Another notable patent involves a method for etching polycrystalline semiconductors. This method includes performing a cyclic plasma etch process with multiple cycles. Each cycle involves etching a patterning layer made of polycrystalline semiconductor material to form or extend a recess. This is achieved by exposing the substrate to a first plasma, which is layered over an oxide layer, followed by exposure to a second plasma containing dihydrogen, and finally extending the recess with a third plasma.
