Latest Patents

Iwano's latest patents include an etching method and a plasma processing apparatus. In his etching method, plasma from a processing gas containing a fluorocarbon gas is formed within a chamber of a plasma processing apparatus. This process results in a deposit containing fluorocarbon on a substrate, which consists of a first region made of silicon-containing material and a second region made of metal-containing material. Following this, plasma from a rare gas is introduced, allowing rare gas ions to etch the first region using the fluorocarbon deposit. A unique magnetic field distribution is created by an electromagnet, enhancing the etching process.

Another notable patent involves a method of etching and a plasma processing apparatus. This method entails etching a first region by plasma etching, ensuring that the upper surface of this region is positioned deeper within the substrate than a second region. A deposit containing carbon is formed on the substrate through plasma of a hydrocarbon gas inside the chamber. The etching process is further refined by employing a magnetic field distribution that optimizes the etching efficiency.
