A SAW sensor module can be produced with a true all quartz sensor package (TAQSP) attached to a substrate. The TAQSP has a quartz cover direct quartz bonded to a SAW sensor on a quartz substrate. The TAQSP can be mass produced by direct quartz bonding a quartz cover wafer, having many covers, to a quartz sensor wafer, having many sensors, thereby producing a wafer tandem. The wafer tandem can be further processed because the bond protects the sensors within. Individual sensor packages can be obtained by cutting stripes out of the cover wafer, revealing SAW sensor bonding pads, and then dicing the wafer tandem. A SAW sensor module results when the sensor packages are attached to an antenna bearing substrate and then sealed. |
