VastVision’s metal micromachining program specializes in thick, high-aspect-ratio uniform metal and metal-alloy structures that fall below the reach of conventional machining. Rather than removing material, we grow it: using lithographically defined molds and bottom-up electroforming, finished with precision planarization. The result is functional coatings and 2.5D electroformed parts for demanding applications across quantum, energy, RF, and medical imaging.
Our metal micromachining work is grounded in electrochemistry research and development, the theoretical and practical basis for depositing dense, uniform, high-aspect-ratio metal:
Dedicated fabrication labs give us full-spectrum process development, from mask design through finished part:
We deliver finished, functional hardware, not just process demonstrations:
Three tightly coupled steps take a design from mask to finished, characterized part.
A precise, photoresist mold is built on a metalized surface. UV exposure transfers the device geometry into the resist, defining the walls the metal will grow within:
Metal is grown from the bottom up, not machined from the top down. Jets of metal solution fill high-aspect-ratio molds to build dense, uniform structures:
Formed structures are lapped and polished to a precise, uniform finish using progressively finer diamond media:
Three dedicated laboratories carry a build from lithography through electroforming to final finish, with in-line metrology at every stage.
Class 100 cleanroom for mold definition and resist processing:
Electroforming plus in-line metrology to verify every build:
Precision finishing to final tolerance:
Our metal micromachining capabilities support advanced programs including:
