LITHOS
A desktop analog foundry. Load a wafer, walk away, return to working analog silicon.
01 · Mission
Silicon should be made by the people who need it. Not booked, queued, and waited on.
LITHOS is an oven-sized lithography machine built for analog chips: op-amps, references, filters, sensor front-ends. Slide in a wafer, pick a layout, and it quietly handles coating, exposure, developing, and inspection. An analog foundry on your bench, without the cleanroom.
02 · Process
Load. Walk away. Return to silicon.
Six steps. About an hour per layer. The analog recipes are written down in plain language so you can follow along, or hand them to a student.

Whoever needs their own silicon.
Universities
A full analog IC course: design, fabricate, and probe real silicon in one semester. No cleanroom, no waiting list.
Research labs
Test structures, novel devices, microfluidics masters — patterned on your own bench the day you need them, not when the shared facility has a slot.
Individuals & clubs
Print your own op-amps and sensor front-ends at home. One machine, a whole community of analog builders. Shared recipes, shared PDK.
Companies
Pattern the parts you cannot buy: sensing elements, electrode geometries, micro-heaters matched to your product. In-house, on your schedule, your IP.
04 · Why custom
Own the pattern, own the product.
The structures your product depends on were never for sale — and getting them made means borrowing someone else's cleanroom, on someone else's schedule.
Not in any catalog
Your electrode geometry, micro-heater, or sensing structure exists only because your product needs it. Nobody sells it.
The real cost is the queue
Shared cleanrooms mean training, booking, waiting. Owning the machine turns an iteration into an afternoon.
Your design stays home
Outsourcing means your geometry and process leave the building. On your own bench, they never do.
Parts die. Products shouldn’t.
One EOL’d component can kill a whole product. Pattern the replacement in-house and keep it alive.
