NANO-019
Nanofabrication & Lithography
PhotoBattery can define, execute, and validate this work as a measurable engineering engagement - from specification freeze and method selection through evidence review, acceptance testing, and decision-ready recommendations.
Nanofabrication Critical-Dimension & Overlay Metrology is a structured engineering service for organizations that need a defined technical answer, a validated process or test path, and evidence suitable for the next design, qualification, or investment decision. The work can address SEM-based dimensional measurements; optical or e-beam alignment assessment; line-width mapping; overlay error; feature-height analysis; statistical variation. PhotoBattery selects and applies thermal/e-beam evaporator; crystal thickness monitor; lift-off workflow; profilometer; four-point probe; ICP-RIE/RIE or DRIE tool, then evaluates the result against critical dimension and overlay measured; defect density mapped; pattern-transfer fidelity quantified; traveler ready for repeat fabrication.
Our team translates your technical objective into a controlled work package with the right tools, evidence, checkpoints, and acceptance criteria. You receive traceable results and a practical next-step recommendation rather than a generic assessment.
Engagements begin with the samples, architecture, process history, operating limits, and success metric you provide. We then confirm the test or engineering path, control measurement uncertainty, document dependencies and risks, and align the deliverables to the decision you need to make.

| Lead discipline | Best staffed by a nanofabrication engineer |
Best staffed by a nanofabrication engineer. Engagement should begin with a one-page specification freeze, sample/data access plan, and acceptance-metric agreement. Avoid claiming production readiness until repeatability, measurement uncertainty, and process ownership are documented.
