Latest Patents

One of Horwitz's latest patents is titled "Electrostatic Chuck with Improved Release." This invention addresses a common issue faced by electrostatic holding devices used in semiconductor wafer processing. The problem arises when a residual electrostatic charge builds up on the device's surface, making it difficult to release the wafer after processing. Horwitz's invention overcomes this challenge by determining a specific drive voltage to be applied to the electrostatic chuck. This voltage effectively cancels out the holding effects of the residual charge, allowing for the smooth release of the wafer. The drive voltage is adjusted based on monitoring the motion of the wafer, ensuring that it is not being gripped by the device.

Another significant patent is the "Electrostatic Chuck Using A.C. Field Excitation." This innovation further enhances the functionality of electrostatic chucks in various applications.
