Latest Patents

One of his latest patents is titled "Enhanced high pressure cleansing system for wafer handling implements." This invention provides methods and apparatus for cleansing contaminants from substrates, such as semiconductor wafer handling implements. The goal is to reduce the incidence of contamination of semiconductor devices being assembled upon the semiconductor wafers. In this invention, a substrate, such as a semiconductor cassette, is inserted into a chamber that is isolated from the surrounding environment. A pressurized cleansing medium, which can be an inert gas like nitrogen, is directed against the substrate surface to dislodge contaminants. The dislodged contaminants are then evacuated from the chamber using negative pressure. The cleansing medium is applied at pressures ranging from about 10 p.s.i. to over 100 p.s.i. The chamber is designed with sidewalls that create a convergent evacuation path, ensuring efficient removal of contaminants.

Another notable patent by William D Light is the "Cleansing process for wafer handling implements." This patent shares similar methodologies for cleansing contaminants from substrates, emphasizing the importance of maintaining the integrity of semiconductor devices. The process involves inserting a substrate into a chamber, directing a pressurized cleansing medium against it, and evacuating dislodged contaminants. The use of an inert gas and controlled pressure is a key aspect of this invention, which aims to enhance the overall cleanliness of semiconductor manufacturing processes.
