COMPARISON OF TAT HYBRID MEMS* TO SINGLE STRUCTURE MEMS,

TAT HYBRID MEMS                                SINGLE STRUCTURE MEMS

 INHERENTLY HIGH ACCURACY             MORE ERROR STRAIN SENSITIVITY

INHERENTLY MORE STABLE/TIME          SUB MICRO STRAIN VS. TIME DEPENDENT

REJECTS BATCH/BATCH VARIABLES     BATCH TO BATCH VARIABLE SENSITIVITY

LOW SENS. TO ELECT. ERRORS               SENSITIVE TO ELECTRONICS INSTABILITY

INHERENT FM DIGITAL                             ANALOG SIGNAL

NO ELECTRONICS TRIMMING                  TRIM COMPONENTS AND/OR POTS.

NO CRITICAL PROCESSES                         CRITICAL PROCESS CONTROL REQD

NO SPECIAL CAL EQUIP                            SPECIALIZED CAL EQUIPMENT

NO SPECIALIZED METROLOGY                SPECIALIZED METROLOGY

FULL 3-D DESIGN FLEXIBILITY                LIMITED TO 2-D OR CONSTRAINED 3-D

LOW COST PRODUCT UPDATES              VERY COSTLY PRODUCT UPDATES

FAST RESPONSE TO MARKETS                VERY SLOW MARKET RESPONSE
 

* TAT hybrid MEMs is a combination of a quartz crystal MEMS and a unique but essentially conventional assembly which transfers the load to the MEMs.  This combination gives the best of both worlds for a wide range of transducer types.
