Latest Patent Applications

Minseok Seo's latest patent applications include two notable inventions. The first is a "PLASMA ETCHING DEVICE AND METHOD OF OPERATING THE SAME." This device features a source power generator that generates a source power signal based on a source control signal. It also includes a bias power generator that produces a bias power signal based on a bias control signal. The device is designed to optimize the etching process by utilizing an inductively-coupled antenna and a wafer support member. The source power generator is capable of detecting the operation of the bias power generator and can perform a frequency switching operation based on this detection.

The second application is for a "MASS FLOW CONTROL DEVICE AND ZERO POINT CALIBRATION METHOD FOR THE SAME." This method involves calibrating the zero point of a mass flow control device by closing a valve in the main flow path to prevent fluid flow. It includes determining whether the fluid has stopped flowing and whether it is stable, based on pressure and flowrate measurements. The calibration value is calculated using temperature and flowrate data, ensuring accurate measurements for the device.

Conclusion
