Preventive maintenance (PM) for LAM 9600, Versys 2300, and Exelan 2300 metal etch tools is essential but often time-consuming. These high-vacuum chambers operate with corrosive plasma chemistries and require ultra-clean conditions, making thorough and consistent cleaning a priority. However, the traditional method of using polyester wipes manually soaked in IPA or DI water introduces:
-
Variability
-
Oversaturation
-
Risk of moisture ingress
The Better Solution: MiraSAT™ EHS Pre-Saturated Wipes
Foamtec’s MiraSAT™ EHS wipes are pre-saturated with 13 mL of UltraPure Water (UPW) per wipe, offering a safer and more effective alternative. Compatible with both legacy and modern LAM platforms, MiraSAT EHS enables:
-
Faster PM cycles
-
Reduced tool corrosion risk
-
More consistent cleaning outcomes
Problems with Manually Wetted Polyester Wipes
Using traditional polyester wipes introduces multiple issues during PM:
-
Over-Wetting & Dripping: Causes fluid pooling near gate valves and pump ports.
-
Poor Absorption: Requires multiple passes and increases the risk of smearing.
-
Moisture Ingress: Promotes corrosion in roughing and turbo pump lines.
-
Technician Variability: Leads to inconsistent results across PMs.
These problems are amplified in Versys and Exelan chambers due to their complex geometry and tight clearances.
Why MiraSAT™ EHS Outperforms
MiraSAT™ EHS wipes solve these challenges with a precision-engineered design:
✅ Controlled Moisture Application
Delivers a uniform 13 mL UPW dose—enough to clean effectively without dripping.
✅ Superior Cleaning Performance
Microfiber substrate lifts and retains particles and residues better than polyester, even with stubborn post-etch aluminum and polymer buildup.
✅ Faster Chamber Recovery
Reduces over-wetting and moisture entrapment, allowing faster vacuum recovery and tool ramp-up.
✅ Corrosion Prevention
Minimizes moisture near sensitive components like forelines and turbo ports—reducing corrosion and oxidation risk.
Comparison Table: MiraSAT™ EHS vs. Manually Wetted Wipes
| Feature / Risk Area | Polyester + Manual Wetting | MiraSAT™ EHS (13 mL UPW) |
|---|---|---|
| Fluid Control | Inconsistent, technician-dependent | Uniform, metered 13 mL dose |
| Cleaning Performance | Low absorption, high smear risk | Microfiber, excellent particle lift |
| Chamber Recovery Time | Variable, often delayed | Predictable and faster |
| Moisture Migration Risk | High (into ports and recesses) | Very low |
| Corrosion Potential | Elevated in roughing lines | Dramatically reduced |
| PM Time & Consistency | Longer, variable | Shorter, repeatable |
