Wish list:

Item Needed/suggested (USD) Why Notes
Sponsor a chip image! 20-100 Moar data! Non-commercial only, you provide IC. Usually top metal as delayering requires some to a lot more work
Keep the lights on 75/year Prevent canceling website when I need beer money Free hosting offers are appreciated but will be politely turned down
Real SSL cert 200/year Makes your browser happy Tried StartSSL but they didn't get back to me
Second (quality) CNC microscope operational 560 Increased throughput See below
Mitutoyo Plan Apo 50x objective 800? Better images, relieves imaging constraints Assuming one pops up on eBay. Olympus 50x ULWD clearance issues
Confocal microscope 2,000 Much easier automated polygon capture Typical industrial auction price
Better lapping machine 2,000 Faster/better/safer delayering Used price
Gold sponsor 1000 Because you love me? Selfish advertising? Get your company logo on the site?

The server isn't free, the equipment isn't, and my time is limited. I enjoy sharing information but its encouraging to know people appreciate it. If you donate I'll be more than happy to help you out by working on an article of your choice or imaging something of your choice.

If you have some interesting chips I'd probably take them to image as well. Be warned though I have quite a stockpile (ie backlog) of chips already but I'd like to help others out to spread interest. Be warned that I'm less likely to help you gratis if you have commercial interests

Sponsoring a chip

Consumables used for every chip:

  • Acid (typically H2SO4 or WFNA)
  • Filtered canned air
  • Acetone
  • IPA
  • Deionized water
  • Paper towels
  • Gloves
  • Electricty
  • Stuff ocassionally breaks! (eg glassware)

Time invested into every chip:

  • Trimm package
  • Remove paddle
  • Remoe epoxy
  • Remove bond wires
  • Clean
  • Level for imaging
  • Image
  • Find image features
  • Optimize image alignment
  • Stitch images
  • Upload images

None of these are bad by itself but add up. The equipment also ain't cheap and would love it if someone could help me offset the costs. Also it adds up to a few hours per chip to go from epoxy package to stitched image

Delayering ranges from dangerous to very time consuming. HF will work decently for most single metal chips but is a little dangerous to work with even at low concentrations. Also at least a couple of hours work for good results. Lapping generally produces good results but is very time consuming, say 8+ hours of work.

Second microscope

Have:

  • Heavy duty motorized XY stage w/ rotary encoders + glass linear encoders + motor controllers
  • Spare high quality microscope base for XY stage
  • Most of a BH2-UMA
  • Unused NeoSPlan objectives
  • Extra STM32 to turn into indexer
  • Microscope cameras but would require writing more Linux drivers

Need:

  • BH2-UMA missing BH2-HCL (~$50) + BH2-LH50A (~$150)
    • A lower quality illuminator would discourage its use
  • MU800 camera ($210)
  • A table in the garage ($50? free on craigslist?)
  • Leveling mechanism: may be able to scrounge from existing stockpile but more likely $150
