 In general I want to focus on R&D / labwork and not hand digitization.  I do have some limited semi-automatic digitization capabilities for planarized chips though that I'd like to develop (ex: works on PS1 chipset). In general I want to focus on R&D / labwork and not hand digitization.  I do have some limited semi-automatic digitization capabilities for planarized chips though that I'd like to develop (ex: works on PS1 chipset).
  
-Most of this is targeted towards small chips up to the mid 90's.  If the die is obnoxiously large (ex: 486 CPU) it will be difficult for me to photograph and stitch the entire thing.  Similarly most of my equipment is targeted towards larger processes (say 180+nm), although I do have a small SEM if required. See [[https://siliconpr0n.org/map/xilinx/xc2c32a/lap4-04_mit20x/|XC2C32A]] for an example 180 nm chip taken with a relatively low power objective, noting in theory I can get about 11x the detail (NA 0.42 => 1.4).+Most of this is targeted towards small chips up to the mid 90's.  If the die is obnoxiously large (ex: 486 CPU) it will be difficult for me to photograph and stitch the entire thing.  Similarly most of my equipment is targeted towards larger processes (say 180+nm), although I do have a small SEM if required.

 Other: most of the work is in decapping, not actual imaging. If you happen to already have a bare, clean die and would be satisfied with a quick / lower quality scan, feel free to send me a few dies. This also can work out well since most of the NRE cost is in the microscope, not the decapping supplies. Other: most of the work is in decapping, not actual imaging.

 +mit20x vs mit20x2:
 +  * mit20x: BH2 microscope, MU800 camera, 0.5x relay lens, Mitutoyo M Plan Apo lens
 +  * mit20x2: BH2 microscope, USB3 camera, 0.75x relay lens?, Mitutoyo M Plan Apo lens
 +    * Select medium resolution 2736 x 1824
 +    * 20x
 +      * 0.42 @ 800 nm => 952 nm R objective resolution
 +      * 0.42 @ 532 nm => 633 nm G objective resolution
 +      * 0.42 @ 400 nm => 476 nm B objective resolution
 +      * About 820 um wide field of view
 +      * 820 / 2736 = 300 nm / pix raw
 +        * Cut image by half to sample RGB correctly => 600 nm / pix
 +      * 820 / 2736 / 0.5 = 599 nm / pix ultimate image resolution
 +    * vc60x => 1.4 NA
 +      * 1.4 @ 400 nm => 143 nm objective resolution
 +      * About 820 / (60/20) => 273 um FOV
 +      * 273 um / 2736 pix / 0.5 pix/pix => 200 nm / pix ultimate image resolution
 +    * Conclusion: possibly losing slight resolution in blue, but probably good enough
