Latest Patents

Among his latest patents is an annealing method that enhances the efficiency of wafer processing. This method involves loading a wafer onto a fork of a delivering robot within an annealing apparatus. The wafer is in contact with a vibration-detecting sensor on the fork, which plays a crucial role in monitoring the process. The fork rotates between a heating plate and a cooling plate, and the vibration-detecting sensor outputs a first signal in response to the motion of the fork. The circuitry of the annealing apparatus then provides a response based on this signal.

Another notable patent is a method of controlling chemical concentration in an electrolyte. This method includes measuring the chemical concentration in a tank and determining a vapor flux through an exhaust pipe based on the measured concentration. A motor connected to a ball screw moves a gate of the valve according to the determined vapor flux. This process allows for efficient electroplating of wafers in multiple cells connected to the tank, while also recycling the electrolyte.
