- | ====== 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. | ||
- | |||
- | 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. | ||
- | |||
- | In terms of consumables, | ||
- | |||
- | Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid). | ||
- | |||
- | This is a hobby and I'm not interested in operating as a business. | ||
- | |||
- | 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 die and would be satisfied with a quick / lower quality scan, feel free to send me a few dies. This may actually work out well for you since most of the money is in the microscope, not the decapping supplies. | ||
- | |||
- | Please provide the following information for each chip: | ||
- | * Required: markings on the chip | ||
- | * Do not just send me the chip code name and expect me to know which one it corresponds to | ||
- | * Ex: specify " | ||
- | * Optional: alternate names | ||
- | * Ex: SWIM, Pentium 1 etc | ||
- | * These are helpful to add to wiki pages | ||
- | * Required: what you want | ||
- | * Full images of every layer so you can digitize it? | ||
- | * Do you need the whole die or just a part of it? | ||
- | * Top metal image for aesthetic purposes? | ||
- | * Are you hoping for high resolution that can see every wire or just an overview shot? | ||
- | * ROM dump? | ||
- | * Suggested method? | ||
- | * Image mask ROM only? | ||
- | * Erase fuses / laser magic? | ||
- | * Optional: datasheet is a plus, especially if I need to do something invasive | ||
- | * If applicable: any previous knowledge of things people tried that didn't work | ||
- | * Required: replaceability/ | ||
- | * Sometimes I can do something more aggressive (faster, sometimes much faster) that might have higher chance of damage | ||
- | * If they are readily available you should send me several just in case | ||
- | * Especially if you want me to do invasive analysis (ex: delayer) | ||
- | * TODO: come up with a scale, but here are some rough figures | ||
- | * Very common: < $5 or can easily get for free | ||
- | * Ex: XC2C32A | ||
- | * Common: can get more if you shell out mild cash | ||
- | * Ex: playstation 1 CPU | ||
- | * Rare: You can probably get more but it might take a while or cost >$100 | ||
- | * Ex: playstation 4 CPU | ||
- | * Very rare: $1000 or un-replaceable | ||
- | * Ex: CSG 4510 R3 (the C65 CPU) | ||
- | * Any other relevant information | ||
- | * Can you provide any funding for the work? | ||
- | * Commercial or personal interest? | ||
- | * I'm not opposed to commercial interest so long as the die images remain free here | ||
- | * Funded projects are given priority | ||
- | * I am willing to do a lot of stuff for free, but it does involve harsh chemicals, costs me money, and time so anything is appreciated | ||
- | * Any legal issues associated with the chip? | ||
- | * Does release need to get restricted? | ||
- | * DRM? Crypto? | ||
- | * Ex: a sound chip is no issue | ||
- | * Do you have a particular timeline in mind? | ||
- | * Between work and other requests don't be surprised if it takes me several months to get to it even if its only an hour of work | ||
- | * Coordinate with me for best results | ||
- | * I usually have the most time late Dec / early Jan | ||
- | * By default I retain copyright and publish work CC BY on sipr0n | ||
- | * If you need exclusive copyright, want to be included in CC license, etc make an explicit agreement with me | ||
