Abstract:
A method of depositing a side wall passivation layer on an etched feature in a semiconductor substrate, comprising placing the substrate in a vacuum chamber, striking a plasma, and introducing a hydrocarbon deposition gas to deposit a carbon or hydrocarbon layer.
Abstract:
This invention relates to methods for treatment of semiconductor substrates and in particular a method of etching a trench in a semiconductor substrate in a reactor chamber using alternatively reactive ion etching and depositing a passivation layer by chemical vapour deposition, wherein one or more of the following parameters: gas flow rates, chamber pressure, plasma power, substrate bias, etch rate, deposition rate, cycle time and etching/deposition ratio vary with time.
