CHAR-011
Materials Characterization & Metrology
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.
Optical Profilometry & Thin-Film Step-Height Measurement 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 three-dimensional surface mapping; step-height extraction; surface waviness; roughness; feature dimensions; comparative process inspection. PhotoBattery selects and applies EBL or mask aligner; spin coater/developer; nanoimprint press if applicable; CD-SEM; overlay metrology; roll-to-roll coater, then evaluates the result against measurement uncertainty stated; spatial resolution/scan grid documented; controls and references included; data traceability preserved.
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.

| Equipment & methods | EBL or mask aligner; spin coater/developer; nanoimprint press if applicable; CD-SEM; overlay metrology; roll-to-roll coater; slot-die/gravure/inkjet head |
| Required client inputs | sample set and controls; expected structure/composition; failure or comparison question; required resolution/uncertainty |
| Deliverables | measurement report; raw and processed data; uncertainty and method notes; interpretation tied to process variables |
| Accuracy / target metrics | measurement uncertainty stated; spatial resolution/scan grid documented; controls and references included; data traceability preserved |
| Lead discipline | Best staffed by a materials characterization scientist |
Best staffed by a materials characterization scientist. 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.
