Libre Silicon

Freie halbleiter für alle

Wir entwickeln einen freien und offenen Standard für Halbleiterfertigungsprozesse und stellen einen schnellen, einfach zu benutzenden und günstigen weg für Halbleiterherstellung bereit. Um anzufangen, seine eigenen Chips herzustellen wird man keine nervigen NDAs mehr unterzeichnen müssen und man kann den Prozess auch in seinem Keller implementieren, falls man das möchte. Unser Ziel ist es den Halbleitermarkt zu revolutionieren und gleichzeitig gegen das Monopol von grossen Halbleiterherstellern vorzugehen!

Die Idee Mehr Infos Einstieg Der Prozess

Öffnung des Marktes

Today there is no inexpensive and easy way for SMEs, startups and hobbyists to develop their own ASICs and bringing them to the market. All the silicon manufacturing nowadays is in the hands of a few big companies which play their monopoly of lone capability of manufacturing microchips by charging around 20'000 USD per prototype and letting an engineer wait for months until she/he can test her/his design physically. Additionally the EDA tools for designing chips are unaffordable for most start ups. We intend to change that!

Auditierbare chips lösen die Sicherheitsbedenken

Since at least the introduction of the Intel management engine the concerns about the trustworthyness of our CPUs is raising. By providing a fully open process and technology node which allows to publish the entire layout on GitHub, the doors for entirely free CPU platforms are being pushed open which allow for a full security audit down to the transistor level. Which means no more possible hidden hardware backdoors for intelligence agencies.

Globale Reproduzierbarkeit

We aim to specify the target parameters of test structures we provide, required for supporting the LibreSilicon technology. If met, it becomes possible to test any ASIC (CMOS *and* analog!) somewhere in Tokyo and then download the design from GitHub and manufacture it anywhere else in the world.

Ein freier Prozess

In order to democratize the semiconductor market and stop being at the mercy of big proprietary semiconductor manufacturers a standardized free manufacturing process needs to be introduced in order to easily exchange designs and silicon verify them anywhere on the globe. That's what we're doing.

David Lanzendörfer

Process Design

Studied electrical engineering but realized that there were no interesting jobs to be done in Switzerland. So he ventured out to China in order find his fortune there. In this new world he found all the thrilling engineering problems, he ever wanted to solve, and now tackles the final frontier: Semiconductor manufacturing.
