Latest Patents

Anca holds a patent for "Methods for in-situ passivation of silicon-on-insulator wafers." This patent describes methods and systems for performing a passivation process on a silicon-on-insulator wafer within a specialized chamber. The process involves cleaving a bonded wafer pair to form the SOI wafer and then passivating the cleaved surface in-situ by exposing it to a passivating substance. This technique results in the formation of a thin layer of oxide on the cleaved surface, which is crucial for improving the wafer's properties. The silicon-on-insulator wafer is subsequently removed from the chamber, ensuring that it remains uncontaminated.
