04/14/2021, 6:30 PMAs currently stands I'll just strip each to transistors image and stop. If you wanted a layer stackup or something like that I'd need more - t
Tim 'mithro' Ansell
04/14/2021, 6:31 PM@User okay, I think strive2 is the highest priority as nobody has gotten that one working yet if I understand correctly... - j
John '/dev/null' McMaster
04/14/2021, 6:31 PM? How do the die images help? - j
John '/dev/null' McMaster
04/14/2021, 6:32 PMI assumed this was mostly for artistic merit - t
Tim 'mithro' Ansell
04/14/2021, 6:32 PM@User Actually, I have no idea :-) @User Would images help? - t
Tim Edwards
04/14/2021, 6:39 PM@User (@User): Given that striVe2 has a gross failure (as in, dead as a doornail) but there are no errors evident in the design, I am currently considering all possibilities. So yes, seeing the transistor-level view of the actual chip is an excellent sanity check, even though it will only show basic structures like transistor gate/source/drain regions. - j
John '/dev/null' McMaster
04/14/2021, 6:40 PM@User what sort of dead? Excessive current? - j
John '/dev/null' McMaster
04/14/2021, 6:40 PMbear in mind I can microprobe etc if you needed something invasive - t
Tim Edwards
04/14/2021, 6:42 PM@User: Not a short. The behavior is consistent with the chip not coming out of reset, as in, having the main power-on-reset signal to all the pads not switching. But it's the same power-on-reset circuit that's on the first striVe chip, and that one works fine. - j
John '/dev/null' McMaster
04/14/2021, 10:32 PMOk, well if you need help debugging it let me know. For now then I'm just going to strip these down to substrate and if people want additional images send me more dies - j
John '/dev/null' McMaster
04/14/2021, 10:33 PMI'll start with optical images around 500 nm resolution and can do better if desired - j

04/16/2021, 8:06 AMThat one has slightly worse image quality but better lighting - t

04/16/2021, 1:21 PM@User: Those are really nice images, thanks! - j
John '/dev/null' McMaster
04/17/2021, 4:34 AMthis one came out nice: https://siliconpr0n.org/map/gsky/sky1/s1-2_mit20x2-2/ - j

04/17/2021, 4:34 AMI'm also trying to take a higher res image of just the center - j

John '/dev/null' McMaster
04/18/2021, 8:15 AMhigh resolution image available. I also briefly tried to SEM one today but I need to remove the rest of the oxide and/or tune up the SEM a bit - j
John '/dev/null' McMaster
05/12/2021, 4:55 AMFYI finally tweeting out some of these - j

05/12/2021, 4:55 AMThis should have probably been the lead tweet: https://twitter.com/johndmcmaster/status/1392341166310379521?s=20 - n

11/25/2022, 7:46 AMJust realized, that there is this dedicated channel for imagery - I've got two devices of MPW1 delayered (Slot 12 at Local Interconnect Layer and Slot 25 at Metal Level 2.t- 2
