Vacuum Chamber & Tool Cleaning Solutions
Remove polymerized by-products and process residues from etch, PVD, and CVD tools with non-damaging cleaning solutions designed to protect critical surfaces and prevent re-deposition.
How to Remove Deposition from Vacuum Chambers Without Damage
Vacuum chambers in semiconductor tools accumulate:
- Polymerized process by-products
- Metal deposition
- Dielectric films
Over time, this buildup leads to:
- Particle generation
- Process instability
- Increased maintenance frequency
- Yield loss
Improper cleaning can make this worse by:
- Damaging chamber surfaces
- Spreading contamination
- Leaving residue behind
Chamber Cleaning Is Often Inefficient or Damaging
Many cleaning approaches rely on:
- Single-method cleaning (wipe or abrasive only)
- Inconsistent operator technique
- Tools that are either too aggressive or ineffective
This results in:
- Incomplete residue removal
- Surface damage
- Re-deposition of contamination
- Extended downtime
What Causes Chamber Contamination and Particle Issues
- Fiber shedding from cleaning materials and *Scotch-Brite™
- Polymerized process by-products
- Metal and dielectric deposition
- Residue left after cleaning
- Agglomerated particles
- Re-deposition during wiping

A Multi-Level Approach to Chamber Cleaning
Remove Residue → Scale Cleaning Intensity → Capture Contamination → Prevent Re-Deposition
Foamtec uses a tiered cleaning strategy to:
- Remove light to heavy deposition
- Protect critical chamber surfaces
- Prevent re-deposition
- Standardize cleaning performance
Vacuum Chamber Cleaning Hierarchy
Level 1: Light Residue Removal (UltraSOLV® Foam Wipes)
For removing:
- Light films
- Early-stage residue
Benefits:
- Non-abrasive
- Low particle generation
- Ideal for routine cleaning
Level 2: Moderate Cleaning (Sahara Foam / Structured Pads)
For removing:
- Adhered residue
- Intermediate buildup
Benefits:
- Increased cleaning power
- Maintains surface integrity
Level 3: Heavy Deposition Removal (Diamond Scrub Pads / ScrubPADS®)
For removing:
- Hardened deposition
- Polymerized buildup
Benefits:
- Controlled abrasion
- Effective removal without uncontrolled damage
Level 4: Aggressive Cleaning (PneuSCRUB® Systems)
For removing:
- Severe buildup
- Large area deposition
Benefits:
- Consistent, controlled cleaning
- Reduced operator variability
Prevent Re-Deposition During Cleaning
One of the biggest challenges in chamber cleaning is:
removed contamination being spread across the chamber
Foamtec solutions are designed to:
- Capture removed material
- Retain particles within the cleaning medium
- Prevent contamination from being redistributed
Impact on Tool Performance and Yield
- Reduced particle contamination
- Improved wafer yield
- Reduced re-cleaning cycles
- Shorter maintenance time
- Improved tool uptime
- Increased process stability
Where Vacuum Chamber Cleaning Is Critical
- Etch tools
- PVD systems
- CVD systems
- Wafer processing chambers
- Process kits and components
Frequently Asked Questions About Vacuum Chamber Cleaning
What is vacuum chamber cleaning?
Cleaning semiconductor tool chambers to remove deposition and process residue.
What causes deposition buildup in chambers?
Process by-products, metals, and dielectric films from etch, PVD, and CVD processes.
How do you remove polymerized residue?
Using controlled cleaning methods that scale from non-abrasive to abrasive as needed.
Why is re-deposition a problem?
Because removed contamination can be spread back onto surfaces, increasing particle risk.
How do you prevent chamber damage during cleaning?
By using a controlled cleaning hierarchy and surface-compatible materials.
