Critical features
Define linewidth, pitch, junction or nanostructure target and measurement method.
APPLICATION / QUANTUM & NANOFABRICATION
Lithography for quantum devices and nanofabrication.
Combine broad-area optical patterning with critical electron-beam features where the process benefits.
ENGINEERING CONTEXT
The decision starts with the real constraint.
Quantum and nanoscale devices require strict critical dimensions, alignment and contamination control. The process plan should reserve electron-beam writing for structures that need it while using optical direct write for larger supporting levels.
Discuss your requirement ↗CRITICAL REQUIREMENTS
Define these before model selection.
Alignment
Set overlay budgets across optical and electron-beam layers.
Process integrity
Specify substrate, resist stack, dose strategy and cleaning constraints.
SOLUTION ROUTES
Continue from requirement to system.
EVIDENCE CHECKLIST
Ask for evidence that closes the decision.
- SEM with scale and conditions
- Field-stitching result
- Overlay measurement
- Process flow and raw test data
TECHNICAL REVIEW
Turn the requirement into a selection brief.
Send the application, critical parameters and any drawing or process information available.
