The company has moved its base to Texas, with facilities in Austin and Lockhart, and is manufacturing pumps, valves, sensors, and control boards in-house rather than sourcing them from existing suppliers.\u003c/p\u003e\u003cp\u003eFab2\u0026#39;s small fabs process chips smaller than standard 300mm wafers and use electron beam lithography, which writes patterns directly without masks. The method is slower than extreme ultraviolet exposure tools, so the company positions itself for rapid prototyping and low-volume production rather than competing with leading-edge foundries. Fab2 is also developing a browser-based EDA tool called Studio that handles layout, schematics, and simulation.\u003c/p\u003e","blueskyPost":"Atomic Semi rebrands to Fab2 and builds a factory that mass-produces small chip fabs.
