As a core product line under Semiconductors Quartz, high-purity SC quartz tanks are the foundational purity carrier for Wet Benches across four mainstream wafer wet cleaning formulations: APM, SPM, HPM and HF/DHF. As process nodes advance to sub-7nm, wet cleaning directly determines the upper limit of wafer yield, and the material quality of process tanks is the foundation of cleaning purity. This article explains the material properties of our Semiconductor Level SC Quartz Tank For SPM DHF AMP HPM Wet Benches, its necessity for wet process purity control, and its targeted applications across key cleaning process steps.
2. What
Semiconductor Level SC Quartz Tank For SPM DHF AMP HPM Wet Bench Cleaning
Our Semiconductor Level SC Quartz Tank is an ultra-clean wet process vessel under the Semiconductors Quartz portfolio, manufactured from premium synthetic fused silica through high-purity smelting, precision CNC machining and Class 100 chemical cleaning. It is specially designed for 8-inch and 12-inch wafer Wet Benches and RCA cleaning lines, fully compatible with SPM, DHF, APM and HPM full-process chemical environments.

Matching quartz accessories such as wafer guides, lifting carriers and heating tubes are also available to form a complete wet process solution.
3. Why
High-purity quartz wet bench tanks are essential for advanced-node wet cleaning lines for four core reasons. First, ultra-low metal ion precipitation effectively avoids secondary metal contamination on wafer surfaces during long-term immersion, which is critical for maintaining high yield at sub-7nm nodes per industry manufacturing guidelines.
Second, outstanding chemical corrosion resistance reduces particle shedding under strong acid, strong alkali and high-temperature environments, extends component service life and cuts unplanned Wet Benches maintenance downtime.
Third, minimal thermal expansion coefficient ensures dimensional stability across 50℃ to 150℃ process temperature fluctuations, guaranteeing consistent etching and cleaning precision across different formulation recipes.
Fourth, stable electrical insulation and low-adhesion quartz surface help maintain uniform fluid field inside the tank and reduce residual pollutant adsorption after UPW rinsing.
4. How
In 12-inch wafer RCA Wet Benches production lines, our SC quartz tanks are deployed across all four core wet cleaning formulations, each engineered to match specific process conditions:
1. For APM (SC-1) particle removal processes: The quartz tank with integrated temperature control maintains a stable 50–80℃ alkaline peroxide environment, supporting uniform undercut lift-off of particles without introducing extra surface roughness damage to silicon wafers.
2. For SPM (Piranha) organic removal processes: High-purity fused silica construction withstands 120–150℃ concentrated sulfuric acid-peroxide mixtures, resists strong oxidation and minimizes sulfur residue carryover to subsequent process steps.
3. For HPM (SC-2) metal contamination control: The ultra-low metal background of the quartz vessel ensures no secondary ion precipitation during hydrochloric-peroxide cleaning, maximizing metal ion complexation and removal efficiency.
4. For HF/DHF native oxide etching: The high-purity quartz tank maintains stable dilute HF chemistry, avoids impurity-induced wafer surface staining and supports precise time control for HF Last critical processes.
