On the composition library: The 342 composition points per campaign result from a continuous lateral composition gradient inherent to the co-sputtering geometry, not separately controlled discrete depositions. For production of a single target composition, controlled uniform depositions are available following campaign-based identification.

Campaign

How a campaign works.

A campaign replaces sequential material evaluation with a single, complete composition-property map. A first campaign can serve as a standalone initial study. Multi-round programs use earlier results to direct subsequent runs toward the most informative composition regions.

01
Define the space

Identify elements and composition ranges. We will scope the right sub-space and characterization targets together.

02
Deposition run

Up to 7 elements co-sputtered onto a 100 mm wafer in one run. 342 unique thin-film compositions. Real physical samples.

03
Automated characterization

Every composition point is measured for the relevant properties: phase, mechanical, electrical, electrochemical, optical, or magnetic.

04
Composition-property map

You receive a full dataset showing where the properties you need exist across the scanned composition space.

05
Iterate

Bayesian optimization uses results to direct the next campaign toward the most informative composition sub-spaces.

06
Validated candidates

Target compositions are produced as controlled uniform depositions for downstream validation, prototyping, and scale-up.

Applications & Use Cases

Where the platform applies.

The platform is suited to any problem where composition determines functionality and the relevant space is too large to navigate one material at a time. The following domains represent active and completed campaigns.

Electrochemistry
Water electrolysis catalysts

Activity-stability tradeoffs mapped across HEA composition space using the Scanning Droplet Cell. Published results across the Ni-Pd-Pt-Ru and Co-Fe-Ni systems.

Electrochemistry

Electrochemistry
Bipolar plate coatings

Corrosion potential mapping via SDC and contact-resistance mapping via 4-point probe across multi-element composition gradients.

How it works

Combinatorial co-sputtering: Up to 7 elements are deposited simultaneously via magnetron sputtering in a single run. DC, RF, pulsed DC, HiPIMS, and reactive sputtering (N2, O2) are all available, covering metals, alloys, nitrides, and oxides. The composition varies continuously across the wafer, producing a laterally resolved library of 342 unique thin-film compositions.

Multi-element and high-entropy systems: The platform was built for composition spaces too large to navigate sequentially. Core operating domains include transition metal nitrides, high-entropy alloys, and multi-component oxides. Transition metals and their combinations form the primary operational range of the system.

Initial study or multi-round campaign: A campaign can be a single exploratory study or a multi-round program. The first run maps a slice of the composition space. Subsequent campaigns use property data from earlier runs to direct focus toward the most informative regions.

From composition map to prototype: Once a campaign identifies target compositions, controlled uniform depositions on flat or structured substrates are available for downstream validation and prototyping. Scale-up to production is handled via established manufacturing partners.
