====D9====

==Past:==

D9 was proton exchanged for 10 minutes and annealed for 45 minutes. 

Prepped with pmma and aqua save for ESEM.

Written in ESEM at Spot 5 for long transducers, developed for 1 minute. 

Evaporated 200nm Aluminum, placed in NMP for liftoff. 

Liftoff was successful.

The day after impedance matching all the Mid and High transducers had a circle around the outside of the Smith Chart.

Under the microscope they look like this:

Low F

Mid F

High F

Close Up

Update 5/26/2015: Now every transducer on this device is displaying the open circle. I believe that all the transducers on this device are broken. It appears that a signal greater than 25 Dbm causes one of the busses to overload and burn up.

==Current:==
Clean off and reuse.
