What this segment covers

Tools and process work that remove material, residues, or photoresist without damaging the wafer pattern.

Each tooling segment draws on a different mix of disciplines and support roles. This brief lists the role families, bottlenecks, and public signals tied specifically to etch, clean, and strip.

Capability taxonomy

Capabilities attached to this segment

Each capability names a discrete technical problem a competent supplier has to solve. The list is taxonomy and should not be read as a score.

ECS01

Plasma source and sheath control

Create a stable plasma and independently shape ion density and ion energy so the tool removes the intended material with the intended directionality.

Core problems: ICP/CCP source design; RF matching; ion energy-density decoupling; chamber repeatability; wafer temperature interaction with plasma.

ECS02

Profile, selectivity, and high-aspect-ratio transfer

Translate a mask pattern into the film stack without collapsing profile control or attacking adjacent materials.

Core problems: Etch rate; anisotropy; selectivity; CD/profile control; microloading; aspect ratio effects; residues; endpoint strategy.

ECS03

Post-etch clean and residue removal

Remove polymers, particles, metals, and native contamination so the next process starts from a stable surface.

Core problems: Residue chemistry; particle removal from patterned wafers; metal contamination; no pattern damage; chemical compatibility with prior films.

ECS04

Strip and rework-safe material removal

Remove photoresist or metal-removal residues quickly and safely without destroying pattern fidelity or surface quality.

Core problems: PR strip; metal strip; solvent/acid compatibility; throughput vs damage; chemical consumption and recovery; safety and filtration.

Role families

Role families attached to this segment

These are the kinds of people the segment relies on. Public sources reveal each role family with different visibility.

ECS_RS

Research scientists

Invent or validate new plasma regimes, chemistries, chamber materials, surface interactions, and residue-removal mechanisms.

Typical titles: Plasma scientist; surface scientist; cleaning chemist; materials scientist

Public observability: Medium

ECS_PE

Production engineers

Own recipes, DOE, process windows, installation debug, chamber match, customer ramp, and failure analysis.

Typical titles: Etch process engineer; clean/strip process engineer; application engineer; field application engineer

Public observability: High

ECS_TE

Technicians

Run PM, swap consumables, execute checklists, resolve first-line faults, and support release-test or install work.

Typical titles: Equipment technician; installation/debug technician; test technician; cleanroom maintenance technician

Public observability: Medium

ECS_TK

Tacit production know-how

Chamber seasoning; alarm triage; tool matching; handoff timing; residue-risk intuition; fab etiquette during ramps.

Typical titles: Held by senior process engineers; senior field engineers; shift leads; master technicians

Public observability: Weakly observable

Likely bottlenecks

Where the hard problems sit

  • High-aspect-ratio profile control with low damage
  • Post-etch residue removal without pattern loss
  • Chamber matching and recovery after maintenance

Public signals

What public records tend to reveal

  • Etch and clean product pages
  • CNINFO annual-report disclosures
  • Process and application job language
  • Patents and technical papers on plasma or wet clean

What to watch

Signals worth checking next

  • Repeat references to advanced memory and high-aspect-ratio use cases
  • Service and application-team expansion
  • Training language tied to customer-site ramps

Do not infer

Limits of the public record

  • Capability and role-family counts on this page describe how much taxonomy is catalogued. They do not measure workforce size, market share, or capability.
  • Public signals expose product families and role language. They do not expose yield-learning depth, customer-site quality, or segment-specific headcount.
  • Public sources expose product families and role language better than yield-learning depth.

Source trail

Anchor sources for this segment

These are the source records this brief leans on most. The full source ledger is available on the sources page.

CN_FIRM_AMEC

Advanced Micro-Fabrication Equipment Inc. China

AMEC · official company product page

Core source for etch and deposition product-line mapping and for the lithography-constraint side note that China is stronger in etch/deposition than lithography.

Caveat: Corporate source; English site emphasizes product families more than personnel data.

CN_FIRM_ACM_SH

盛美半导体设备(上海)股份有限公司

ACM Research Shanghai · official company page

High-value clean-tool source with wet cleaning, electroplating, furnace, track, and PECVD coverage; especially useful for clean/strip and adjacent front-end tools.

Caveat: Corporate source; some claims are marketing-oriented.

Etch product maturity and R&D composition.

Caveat: Listed-company disclosure; product and workforce data are aggregated.
