Latest Patents

One of his latest patents is the "Impedance measurement jig and method of controlling a substrate-processing apparatus using the jig." This invention includes a first contact plate, a second contact plate, a cover plate, a plug, and an analyzer. The first contact plate makes electrical contact with an ESC in a substrate-processing apparatus, while the second contact plate contacts a focus ring surrounding the ESC. The cover plate is designed to cover the upper surface of the substrate-processing apparatus. The plug can selectively make contact with either the first or second contact plate. The analyzer applies power to both contact plates through the plug to measure the impedance of the ESC and the focus ring individually, allowing for thorough inspection.

Another significant patent is the "Memory device and data initialization method of the same." This memory device features a row decoder that receives normal and control addresses, along with a memory cell array connected via multiple word lines. During normal operations, one word line is enabled in response to normal addresses. However, during initialization, at least two word lines are enabled, allowing for the initialization of data in the memory cells connected to those lines.
