Morning Chippers, Some rough calculations on chips per 300mm...

Morning Chippers,

Some rough calculations on chips per 300mm diameter silicone wafer.

My original calculations were working on the chiplet size being 15mm x 15mm = roughly 240 chips per 300mm silicone wafer x 6 wafers per shuttle = 1440 chips.

Having recently seen that the total finnished AKIDA 1000 Chip actually fits inside the diameter of a ten cent coin & having had a look at a physical chip construction / assembly, I have re drawn a 300mm diameter wafer and gridded at what I belive would be the biggest chiplet size under the metal cover of our AKIDA 1000 chip.

I am thinking no larger than 9mm x 9mm for the chiplet.
So on a 300mm dia. Wafer = 648 chiplets.
* This is after taking out the partial chips around the circumference & allowing 1mm for cut between chips.

648 chips X 6 wafers per shuttle = 3888 chips.

Cost per wafer roughly $2860 plus 20% ( rise in cost of production) = $3432 per wafer x 6 wafers = $20592.

= $9.70 USD per chip cost.

Going from 15mm x 15mm to 9mm x 9mm in size
= 2448 extra chips.
= or a extra 170% yield.

Keep in mind this is all rough calculations and the actual chiplet s could be smaller again.

Interesting I thought.
