JM unit: advert called it "Hummer II Sputter Coater for Au" although it doesn't actually say that anywhere on the machine

Have a bunch of internal photos. Will add them + better pictures once I finish overhauling it.

TODO:

  • Fix ATM switch
    • Stuck closed
  • Panel: clean
  • Panel: fix handle / order screw(s)
    • Replace with SHCS?
    • Thread size?
  • Panel: fill out all screws
    • Replace with SHCS?
    • Thread size?
  • Pump: slowly leaking oil?
  • Pump: oil mist filter
    • Where does it go? Thread?
  • HV: fix negative lead. Currently alligator clipped
  • TC: replace sensor
    • Rusted
    • Key is broken
    • Seems to work though

DONE

  • Demonstrate plasma. System seems to more or less work
  • General cleaning
  • Pump: oil was low but now halfway on window
  • Pump: window dirty. Tried to clean but not much success. Probably okay as is

General notes:

  • TC sensor: Teledyne DV-23. Orange base
  • Pump: Sargent Welch 8810

mcmaster Hummer IV

Got from craigslist a while back, including gold source. A little dirty, but worked fine. Cleaned up front panel best I could

2018-08-07:

  • Pedestal does not stay tight and can be easily moved up and down when tightented
  • Threads had eroded on pedestal clamp. I tried to shore them up with PTFE tape, but maybe not enough
  • Ordered "PARKER P8MC6 Connector, Poly, CompxM, 1/2Inx3/8In" to replace it
    • Looks like want P8MC8

2018-08-08:

  • Chamber glass
    • 5" OD
    • 4.5" ID
    • 0.25" thick
    • 6" tall
  • Chamber seals
    • PORTER SEAL COMPANY-DALLAS
    • L shaped
    • 1/2" tall
    • 3/8" wide
    • ~0.073" thick
    • Bell jar L gasket

2018-08-20

  • Install banana plug to ground pedestal
  • Order cap to attach to pedestal
    • Shaft is about 0.37"
    • Something like: [4]
  • Install metal backing plate into TITE connector
    • Much stiffer now
    • Scratching post a little...don't move it
    • Didn't grease o-ring or post. Maybe should have?
  • Was able to sputter coat a sample!
    • First time in several years


mcmaster Hummer VI

Got from industrial auction

2018-08-07:

  • Glass chamber + seals not present
  • No source installed
  • Vacuum pump
    • Model: Trivac D1, 6B
    • Low on oil
    • Remaining oil is clear
    • Put Agilent oil in
    • Black feet at bottom have degraded
    • Black feet stick outside of case...I guess to better isolate the pump from the chamber?
    • TODO: replace feet
    • KF16 inlet and outlet
  • Cleaned up inside unit
    • Oil, degraded pump feet
  • Front panel
    • Cleaned. Lots of black stuff on it
    • Not holding a vacuum. Pressure gauge does not move
    • MODE switch is off center, but otherwise seems to work
    • VAC PUMP switch is not present
  • Its unclear how to properly vent the unit
  • Rear assembly
    • Chamber => electric solenoid => leak valve => cut green tube
    • Rubber hinge w/ chamber top snapped
  • Hummer IV chamber fits, but is probably too tall and slightly too wide
  • Back cover comes off easily
    • Generally much easier to work on this unit than the IV

2018-08-08:

  • Found large gouge on cap
    • Filed down followed by 220, 1500 grit sandpaper
    • Pump ran for a few minutes and reached 50 mTorr
    • Switched to IV pedestal
    • After pumping for 15 minutes reached nearly 20 mTorr
    • Conclusion
    • Pump is good
    • Vacuum tight, including the rear assembly
    • Both pedestals seem fine. Evidence points towards replacing TITE assembly on IV
    • TODO
    • Size / order chamber, seals
    • Investigate leaking chamber
  • Mode tests
    • All three modes seem to roughly work
    • Plate D/C: very slight discharge at top. Suspect plate is too far away
    • Etch D/C: padastel sparkles (reverse polarity?)
    • Plasma Exc: mix of both of above (AC?)
  • Chamber glass diameter estimate
    • Lower platform lip
    • IV: recessed, 3.8 ID, 5.4 OD
    • VI: edge, 3.9 ID, 4.9 OD
    • Upper
    • VI: recessed, 4.9 OD
    • VI: edge, 5.4 OD
    • VI pedestal: 3.75" OD
    • eBay pictures show a chamber not overhanging
    • IV is 4.5" ID, could shrink down 0.5" probably from 5.0" => 4.5" OD
    • But 5" does seem to work and would keep parts compatible. Maybe easier to find
  • Chamber glass height estimate
    • 2.3" gap
    • Current chamber 6", 3.75" is probably right for this one
  • Chamber glass summary
    • Diameter: 4.5 - 5.0" OD
    • Height: 3.5 - 4.0"
    • Width: 0.25"
  • Chamber candidates
