Your full-lifecycle Turnkey ASIC partner - from RTL to Volume Production.
MosChip brings in multi-node expertise (180 to 2nm) and a proven record of successful tape-outs, delivering with first-time right silicon.
Let's connect for your silicon journey!
So here are the photos of the actual chip, taken with a microscope. The black rectangle censors my name. I placed a steel ruler next to the chip in one of the photos to give you an idea of how small it really is. Each black line corresponds to 1 mm
The artwork on the chip is from OggyTheFox (@oggythefox.bsky.social on Bluesky)
In the second picture, you can see that there's always a second chip next to my chip. I don't know what kind of chip it is or why it wasn't separated from mine, but it at least makes the whole thing a little easier to handle because it makes it physically larger x3
I have five chips without a package and five have been bonded into a package, so I'm currently designing a PCB so I can test if the chip works :3
Almost three years ago, when I was still studying at university, I attended a lecture about the design of custom chips (ASICs) and I had the opportunity to design my own custom chip back then. Now, almost three years later I finally have the finished chip in front of me and can take some pictures of it :3
(It took a while before they put it in production, the actual desing only took about two months)
I'll have to wait until tomorrow to get access to a microscope to take photos of the actual chip, but here are some pictures taken in the design environment
Because I had to design the entire chip on my own and within a limited time frame, I chose something not too complicated for the design. The circuit is a 7-segment decoder for 4 different digits with an integrated counter and internal multiplexing
The entire chip is 1.9 mm high and 1.4 mm wide and was designed using a 350nm technology. The first image shows the entire chip (the inner logic surrounded by the IO ring with all the bond pads). The second picture shows the actual logic in close-up. Here you can see all the metal layers that connect everything together. I can't show you any of the silicon layers unfortunately e.g. where and how the silicon is doped and the polysilicon layer used for the transistor gates. Sharing this information is prohibited by the manufacturer of the chip (I had to sign a NDA).
I of course couldn't resist to add some furry art on the topmost metal layer :D
I used a script to convert every pixel of the original image into a metal square of a certain size and place it on the chip in the desing software. It was not easy to get the artwork design rule compliant, but with some manual rework I manged to do so ^^
The image on the chip is only roughly 700um high and 400um wide (0.7mmx0.4mm) (the slots in the scarf are necessary to comply with the desing rules), so it's probably one of the smallest physical furry artworks in existence x3
I really hope that I can take some good photos of the chip and the artwork tomorrow, but I'll have to see if the microscope has enough magnification
