Analyst read
For etch, AMEC is the cleanest public record: product coverage and listed-company R&D staffing read together. The open question is how much of that R&D layer is converting into field application, service, and customer-ramp staffing.

What would change the read
Disclosure that would shift the assessment
- Disclosure of total-employee headcount (would let the R&D share be benchmarked against non-R&D functions)
- After-sales, service, or field-application headcount broken out from R&D
- Repeat-order language for the same etch platform at the same domestic customer
- Master's or doctoral share broken out by R&D function
What to watch
Signals worth checking next
- Platform-specific customer-validation language in filings and product news
- Field-application and service-engineer postings in Shanghai and at customer fab cities
- Training and chief-technician disclosures tied to specific etch platforms
- References to advanced-memory or high-aspect-ratio etch wins
Do not infer
Limits of the public record
- Yield
- Installed-base quality
- Segment-specific headcount
