7800X3D Super Hi-Res Electron Microscope Shot
Added 2023-05-13 23:34:12 +0000 UTCHey, everyone!
Simple post here. The Failure Analysis lab we worked with just sent us a super high resolution Scanning Electron Microscope shot of the Ryzen 7800X3D. It's specifically the cross-sectioned CCD that we showed in our video (already live on the public channel: https://www.youtube.com/watch?v=fFNi3YNJXbY
Since we already published the video, we obviously can't go back and include this image. It doesn't show anything "new" in terms of failures, it's just super cool and educational.
What you're looking at are TSVs, or Through-Silicon Vias, right in the middle in that almost traffic cone-shaped tunnel. There's a scale present on the screen to help illustrate the distances.
Cool stuff! Wanted to share. Thanks for your support, Patreon backers!
(sorry for the annoying watermark - some people were ripping our top-right mark out of the images)

wow checkout the damage on the right side!

The interconnects on the X3D chip are 10500nm tall (10.5µm). it's a veeeeeeeery wide shot

2023-08-17 11:33:06 +0000 UTCWow! I love images like this. Am I correct in remembering that the width of a human hair is typically 50-100µ ? So this entire image is about the thickness of one of my hairs... Absolutely mind-blowing.

2023-05-19 21:59:24 +0000 UTCThe scale at which these devices are manufactured is mind boggling. It's a true wonder that any of it even works at all. Thanks Steve and team.

2023-05-14 01:15:58 +0000 UTCCool image! Dig seeing stuff like this. I haven't watched the entire vid yet, so any additional context about what we're looking at here would be appreciated. :-)

2023-05-14 00:23:13 +0000 UTCVery nice capture. Wondering if what we are looking at is a bottom die with backside TSCVs, an interposer (the cones) connected with Cu pillar with a top route on which the top die is solder on using uBumps.
