    摘要: A T-gate forming method for a high electron mobility transistor includes the steps of: coating a first, a second and a third resist, each having an electron beam sensitivity different from each other, on a semiconductor substrate; performing a first exposure process by using an electron beam on the semiconductor substrate and then selectively developing the third resist; defining a gate head area by selectively developing the second resist to have a developed width wider than that of the third resist; performing a second exposure process by using an electron beam on the semiconductor substrate and then selectively developing the first resist in a bent shape at a temperature lower than in the development of the second and the third steps; and depositing metallic materials on the resists and then removing them to form a T-gate.

    摘要: Provided are an apparatus and method for selecting an optimal signal using auxiliary equalization in a diversity receiver. The optimal signal selecting apparatus includes: a plurality of sync recovery units for extracting sync information from baseband signals, which are candidate signals, except a baseband signal selected as a current optimal signal a plurality of auxiliary equalizers for channel-equalizing the candidate signals based on the extracted sync information; a plurality of SNR measuring units for measuring signal-to-noise ratios (SNRs) of the candidate signals inputted to the auxiliary equalizers and the candidates signals equalized in the auxiliary equalizers; and an optimal signal selector for selecting an optimal candidate signal from the candidate signals by using the extracted sync information and the measured SNRs, and replacing the optimal signal with the optimal candidate signal when reception quality of the current optimal signal is poor.
