SEM-004
Semiconductor Process & Device Engineering
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.
Semiconductor Ohmic Contact & Specific Contact Resistance Optimization 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 metallization-stack selection; surface preparation; contact annealing; barrier layers; work-function matching; oxidation control. PhotoBattery selects and applies SEM/FIB-SEM; AFM; XPS/XRD/Raman; profilometry; statistical data analysis; environmental chamber, then evaluates the result against wafer/device parameter map completed; leakage/breakdown/contact metric quantified; process variation correlated to yield; qualified wafer or recipe criteria defined.
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 semiconductor process engineer |
Best staffed by a semiconductor process 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.
