Sync_ | win. the wafer roboter stopped shooting wafers into the walls of the chamber | 16:29 |
---|---|---|
azonenberg | Sync_: that sounds like a good thing | 16:32 |
Action: soul-d imagining some one modified a clay pigeon shooting device for wafers | 17:17 | |
azonenberg | Lol | 17:17 |
azonenberg | And you shoot them with a FIB? :p | 17:18 |
azonenberg | PULL! *blow away some PIC12F683s with overetched M3* | 17:18 |
azonenberg | PULL! *process characterization wafer is blown to smithereens* | 17:19 |
soul-d | whats a fib ? fast inair beam | 17:19 |
azonenberg | focused ion beam | 17:19 |
azonenberg | which wont work outside a vacuum and is thus highly impractical for skeet shooting | 17:19 |
soul-d | you probably also would like to get rid of gravity if you want to have an effect on it i guess | 17:25 |
Sync_ | it is azonenberg | 19:33 |
Sync_ | the most annoying thing was after you waited 2 weeks for the system to pump down the first waver does not go into the process chamber but BAM right into the wall | 19:34 |
azonenberg | two weeks? What is this | 19:34 |
azonenberg | the longest pump-down delay i've seen was ~2 hrs on a sputtering system | 19:34 |
Sync_ | azonenberg: well, it is an experimental production solution | 22:34 |
azonenberg | oh, i see | 22:35 |
Sync_ | and we need to get around 10^-9 to 10^-10mbar in there | 22:35 |
Sync_ | we have a xrf and such in there, this is why we have the waver handler | 22:35 |
Sync_ | I also do waver calibration, which is insanely boring | 22:37 |
azonenberg | lol | 22:39 |
Sync_ | well, you sit infront of the xray and write down the orientation | 22:53 |
azonenberg | when you say calibration | 22:55 |
azonenberg | do you mean finding the exact angle of the crystal structure to the flat? | 22:56 |
azonenberg | Since i know flats are normally only within a degree or so | 22:56 |
Sync_ | yes | 22:56 |
Sync_ | I determine them to about .05° | 22:57 |
azonenberg | And what are they used for after that? | 22:57 |
azonenberg | KOH and related etches are the only situations i know of that you need orientation that precisely | 22:57 |
Sync_ | mostly experiments with epitactic surface coating | 22:57 |
Sync_ | and isfets | 22:58 |
azonenberg | Epitaxy, that'd do it | 22:58 |
