Latest Patents

Pirooz's latest patents include a method for creating a wafer with regions of low oxygen concentration. This invention describes a single crystal silicon wafer with a thickness ranging from 50 μm to 300 μm. The wafer features a first region that extends a specific depth from the first surface, characterized by a reduced oxygen concentration compared to an adjacent region. This design results in a bulk minority carrier lifetime exceeding 100 μs. Another patent involves producing a ribbon or wafer with similar low oxygen concentration regions. In this process, a ribbon is formed to float on a melt, utilizing a cold initializer that faces the exposed surface of the melt. The ribbon, which is also single crystal silicon, is pulled from the silicon melt at a low angle, ensuring that it is formed at the same rate as it is pulled. The ribbon has a thickness between 50 μm and 5 mm and includes a first region with reduced oxygen concentration relative to the bulk of the ribbon.
