In the video he says Taalas builds a base layer but different routing layers per model (eg. metal 5 - 10 is different per design)
I was wondering if something like this reduces non recurring mask set costs since you could reuse masks for the bottom layers?
The higher metals ones yes because they usually have coarser pitch. Also there are less masks for metal. AFAIK it's one mask for metal and one mask for via and that's it. While the FEOL has finer masks and then a lot more of them for the implants and all that stuff.
I think it has a good chance of working when the production between FEOL and BEOL is split between companies like for example the copper X-Fab BEOL option on IHP SG13.
But otherwise, yeah, not really.

The cool thing about doing something like that is you could potentially have a turn around time of days or even hours.
This is super exciting btw! Going to start working on the base layer and scripting to reconfigure top metal.
Also, is ‘metal’ programmable gate array a name you just made cz that definitely needs to be an official term
