Latest Patents

Tsung-Chi Tsai holds a patent titled "Method of fabricating short-gate-length electrodes for integrated III-V compound semiconductor devices." This patent describes a method that utilizes dual-resist processes to fabricate short-gate-length electrodes, specifically for integrated HBT/HEMT devices on a common substrate. The first thin photo-resist layer defines the gate dimension, while a second thicker photo-resist layer ensures better surface coverage for facilitating gate metal lift-off. This dual-resist method not only reduces the final gate length but also mitigates gate recess undercuts compared to conventional single-resist processes. Additionally, it is beneficial for the fabrication of multi-gate devices with good gate-length uniformity. Tsai's innovative approach has the potential to enhance the performance and reliability of semiconductor devices.
