Latest Patents

One of McMullen's latest patents involves producing a ribbon or wafer with regions of low oxygen concentration. This invention describes a method where a ribbon is formed to float on a melt using a cold initializer. The ribbon is made of single crystal silicon and is pulled from the silicon melt at a low angle. The process ensures that the ribbon is formed at the same rate as it is pulled, resulting in a stable meniscus at the crucible wall. The ribbon's thickness ranges from 50 μm to 5 mm, with a first region that has a reduced oxygen concentration compared to the bulk of the ribbon.

Another significant patent by McMullen is a security system for industrial control infrastructure using dynamic signatures. This invention aims to protect industrial control systems from malicious activities by monitoring dynamic control data. It develops a dynamic thumbprint that can detect deviations from normal behavior, suggesting potential tampering or attacks. The evaluation of this thumbprint utilizes a set of ranges that define normal operation and reflect known patterns of interrelationship between dynamic variables.
