  • Patent number: 11972935
    Abstract: The present disclosure relates to methods of processing a semiconductor substrate in a processing chamber, such as a chemical vapor deposition chamber. The chemical vapor deposition chamber includes a spindle mechanism that cooperates with one or more carrier ring forks to move the semiconductor substrate from one station to another station. The methods include monitoring one or more spindle operation parameters and carrying out one or more maintenance steps on the spindle mechanism based on the results of monitoring the one or more spindle operation parameters. The monitored spindle operation parameters provide an indication of undesirable vibration of the semiconductor substrates in the processing chamber. The vibration of the semiconductor substrates in the processing chamber is undesirable because it promotes generation of unwanted particles that deposit onto a surface of the semiconductor substrate.

  • Patent number: 11955960
    Abstract: The invention uses the control circuit formed on the silicon wafer to detect the leakage current of transistor formed on the depletion mode GaN wafer and then adjust the gate voltage of the depletion mode GaN transistor according to the detected leakage current. Essentially, the gate voltage is reduced or viewed as made more negative when the detected leakage current is larger a specific value. Thus, the gate voltage can be gradually adjusted to approach a specific threshold voltage that right block the leakage current. In other words, by making the gate voltage more negative when non-zero leakage current is detected and even by making the gate voltage more positive when zero leakage current is detected, the depletion mode GaN transistor can be adjusted to have an acceptable or even zero leakage current, a high reaction rate and an optimized efficiency.
