There are few good evaluation methods to evaluate CDM ESD protection performance such as device turn-on speed, etc. A new current-waveform-based method to evaluate the turn-on speed of an ESD protection device is proposed. The method uses two Transmission-Line Pulse (TLP) Tester to investigate the turn-on characteristics of SCR and related devices. Both(More)
Thin film bulk acoustic resonators (FBAR) can be integrated in RFIC as an excellent RF and MF filter. Aimed at high frequency precision FBAR, a new method of evaporating the electrode layer of FBAR by laser is provided to trim FBAR resonant frequency. The experiment results confirm the feasibility of this method and show with a trimming precision up to(More)
