- | ====== Capabilities ====== | ||
- | |||
- | Relevant equipment list: | ||
- | * pr0nscope: CNC microscope. | ||
- | * k2scope: K2 IND CNC confocal microscope | ||
- | * brainscope: laser microscope / probe station. | ||
- | * 2016: 355 nm laser is operational but needs calibration | ||
- | * Misc micropositioners | ||
- | * South Bay Technology 910 lapping machine | ||
- | * Basic jigs | ||
- | * xy-ray x-ray scanner | ||
- | * Small CBCT scanner (ie 3D x-ray) | ||
- | * Note: produces a 3D video but I don't have a software workflow to process into a real 3D model | ||
- | |||
- | Equipment I'd like | ||
- | * SEM and/or FIB | ||
- | * Wedge bonder | ||
- | |||
- | |||
- | ====== Commissioning ====== | ||
- | |||
- | I got a lot of requests to image stuff, so here's my official policy. | ||
- | |||
- | TLDR: for a typical chip, I suggest $25-200 donation to get it decapped and imaged for public use. Delayering is extra | ||
- | * e-mail me (hobby/ | ||
- | * e-mail me (consulting): | ||
- | * [[https:// | ||
- | |||
- | Please provide the following information for each chip: | ||
- | * Can you provide any funding for the work? | ||
- | * Commercial or personal interest? | ||
- | * Decapping involves harsh chemicals, direct expenses, high NRE, and time so contributions are greatly appreciated | ||
- | * Any potential legal issues associated with the chip? | ||
- | * Ex: DRM, crypto | ||
- | * Ex: a typical sound chip or microcontroller is not an issue | ||
- | * Clearly identify the chips, especially if you are sending more than one | ||
- | * Ex: specify " | ||
- | * What deliverables are you looking for? | ||
- | * I assume top metal image at 20x by default | ||
- | * Let me know if you are looking for other services like ROM extraction or delayering | ||
- | * Replaceability/ | ||
- | * Occasionally tings go wrong. How much would it cost to get a second one? | ||
- | * Any previous knowledge? Maybe things people tried that didn't work? | ||
- | * Do you have a particular timeline in mind? | ||
- | * Coordinate with me for best results | ||
- | * By default I retain copyright and publish work CC BY on siliconpr0n.org | ||
- | |||
- | In short, I focus on chips that are of interest to me. I do lots of chips for others, but I give priority to people that are able to provide funds. This section is written with open source projects as the main audience, but note I also offer services through my embedded security consulting service. | ||
- | |||
- | In terms of consumables, | ||
- | |||
- | Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid). Similar issues with staining and lapping. | ||
- | |||
- | I prefer to focus on chips that I can (eventually) release on siliconpr0n.org, | ||
- | |||
- | In general I want to focus on R&D / labwork and not hand digitization. | ||
- | |||
- | Most of this is targeted towards small chips up to the mid 90' | ||
- | |||
- | 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. | ||
- | |||
- | Chips are non-returnable. If you need something back, please make an explicit agreement before sending. | ||

- | ====== Scales ====== | ||
- | |||
- | 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 | ||
