Latest Patents

Kulkarni holds a patent for "Semiconductor processing preclean methods and apparatus." This patent describes a method for semiconductor processing preclean that involves removing an oxide layer from a substrate using anhydrous hydrogen fluoride in combination with water vapor. The system designed for this preclean process is configured to separate the anhydrous hydrogen fluoride and the water vapor until they are delivered to a common volume near the substrate. To limit corrosion within the components of the system, various strategies are employed, including the purification of anhydrous hydrogen fluoride, passivation of components, changing component materials, and heating components. Passivation is achieved by filling a gas delivery component with anhydrous hydrogen fluoride, allowing it to form a passivation layer. Consistent delivery of water vapor is facilitated by heating components using heaters.
