Practical issues with ion beam milling in acoustic resonator technologies

Mishin S., Oshmyansky Y., Bi F., Advanced Modular Systems, Inc, US

A practical approach to addressing production issues of thickness trimming was demonstrated through two-step trimming, send-ahead wafer, and deposition/trimming cluster tool. Thickness control necessary in SAW/BAW technology was demonstrated.

A Novel Approach to Integrate Multiple Frequencies of Film Bulk Acoustic Resonators (FBAR) In A Single Chip

Huang Z., Suo Z., Wang L.-P., Shim D., Ma Q., Intel Corporation, US

Driven by fast growth of wireless communications, film bulk acoustic resonators (FBAR) have been extensively studied as RF filters. Recently, an integrated RF solution, which could include multiple mobile bands, WLAN, Bluetooth, GPS, and etc., [...]
