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.

Smith Charts and SWR for each port Before Impedance Matching (As counted from the top):
| T1 | T2 | T3 |
|---|---|---|

 |  |  |
| T4 | T5 | T6 |

After Impedance Matching (As counted from the top):
| T1 | T2 | T3 |
|---|---|---|
 |  |  |

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.
Future:
