Latest Patents

Among his recent patents is the "Inorganic Rapid Alternating Process for Silicon Etch." This inventive method allows for precise etching of features into a silicon substrate placed beneath a mask within a plasma processing chamber. The process consists of multiple cycles, alternating between a sidewall deposition phase and an etch phase. During the sidewall deposition phase, a flow of inorganic deposition phase gas, which contains silicon and other components like oxygen or nitrogen, is introduced to create plasma in the chamber. The subsequent etch phase involves a flow of etching gas with a halogen component, which is also turned into plasma.

Another notable patent from Aso focuses on "Methods for Protecting Silicon or Silicon Carbide Electrode Surfaces from Morphological Modification During Plasma Etch Processing." This invention provides a technique for applying a protective polymeric coating to silicon or silicon-carbide electrodes within a plasma processing chamber. The protective coating guards the electrodes against damage from plasma constituents and gaseous reactants and can be implemented during both cleaning and etching processes.
