Advanced IC Manufacturing Equipment & Ultra-Clean Processing Solutions
Empowering global semiconductor fabs with controlled chemical processing, high-uniformity wet etching, and controlled microcontamination management for 200 nm processes for maximum IC yield. Discover our company's core focus and values on our about-us page.
Meeting Stringent Cleanliness and Process Repeatability in Nanometer IC Manufacturing
For established semiconductor fabrication at 200 nm process nodes, with selected applications evaluated down to a 100 nm limit, rigorous microcontamination control directly determines overall fab yield. Metallic impurities and fine particulate residues can disrupt pattern transfer, degrade dielectric integrity, and reduce device yield. KOSEN SEMI engineers advanced chemical dispense and ultra-pure wet etching systems specifically designed to support stable processing across critical cleanroom environments.
Front-End-of-Line Surface Purity Tolerances
In Front-End-of-Line (FEOL) wafer surface cleaning, removing native oxide layers, organic contaminants, and trace metallic ions like iron, copper, nickel, and calcium requires absolute cleanliness down to thresholds below 10⁹ atoms per square centimeter. KOSEN SEMI proprietary fluid control technology combines targeted megasonic acoustic energy with optimized chemical formulations to execute damage-free scrubbing across sensitive, high-aspect-ratio gate topologies.
- • Fine Particle Removal: Prevents lattice dislocations and gate oxide breakdown in leading-edge transistor channels.
- • Chemical Cross-Talk Elimination: Isolated fluid delivery pathways prevent reagent migration between sensitive process steps.
Back-End-of-Line Pre-Metallization Treatment
During Back-End-of-Line (BEOL) interconnect processing, persistent chemical residues and 200 nm-class particulate traps create voids and electromigration risks in copper dual-damascene architectures. Our high-uniformity wet processing platforms deliver precise surface preparation prior to metallization, removing polymeric residues without compromising fragile low-k dielectric constants.
- • Ultra-Pure Wet Etching: Ensures highly isotropic dimensional accuracy across narrow contact vias and trenches.
- • Surface Passivation: Inhibits post-clean surface oxidation prior to barrier layer sputter deposition.

01 How do KOSEN SEMI wet processing systems control secondary particle contamination in ISO Class 5–7 environments?
Secondary microcontamination inside ultra-clean semiconductor fabrication lines is eliminated through a multi-tiered engineering protocol built into every KOSEN SEMI tool architecture:
- Aerodynamic Laminar Isolation: Where specified, localized mini-environment enclosures use HEPA or ULPA filtration and controlled vertical airflow to reduce turbulence and airborne particle deposition around critical process zones.
- High-Purity Fluoropolymer Fluid Paths: All chemical contact surfaces utilize semiconductor-grade PFA, PTFE, and high-purity quartz, completely preventing metallic ion leaching and plasticizer outgassing.
- Mag-Lev Fluid Transfer Systems: Seal-less, magnetic levitation pumps eliminate mechanical friction and particle generation in ultra-pure chemical supply lines.
- Point-of-Use (POU) Filtration: Closed-loop chemical recirculation features POU PTFE membrane filters selected according to the required process and cleanliness specification.
02 What process controls protect delicate high-aspect-ratio (HAR) structures during megasonic cleaning and wet etching?
For supported 200 nm processes and selected applications approaching the 100 nm limit, fragile gate structures and HAR trenches risk pattern collapse from surface tension and uncontrolled acoustic cavitation. KOSEN SEMI protects critical topologies through precise fluid dynamic and energy controls across our advanced wafer cleaning systems:
- Frequency-Swept Megasonic Energy: Digital generators sweep acoustic frequencies between 0.8 MHz and 3.0 MHz to distribute energy uniformly without destructive cavitation energy spikes.
- Boundary-Layer Fluid Dynamics: Dynamic chemical dispense nozzles precisely regulate fluid velocity across spinning wafers, mitigating shear stress on supported wafer features.
- Marangoni & IPA Vapor Drying: Surface tension reduction technology utilizes isopropyl alcohol (IPA) vapor gradients to draw liquid out of deep trenches cleanly, bypassing capillary forces that cause line bending.
03 Which aggressive chemistries (e.g., HF, SPM, SC1, SC2) are supported by your automated chemical delivery and anti-corrosion cabinet designs?
KOSEN SEMI automated chemical delivery cabinets and processing modules are engineered to safely supply and recirculate the semiconductor industry's most aggressive wet etching and cleaning formulations:
Hydrofluoric Acid (HF), Sulfuric Acid Peroxide Mixture (SPM), Standard Clean 1 (SC1: NH4OH/H2O2/H2O), Standard Clean 2 (SC2: HCl/H2O2/H2O), and Buffered Oxide Etch (BOE).
N-Methyl-2-pyrrolidone (NMP), photoresist strippers, and specialty solvent formulations requiring active nitrogen purging and static hazard mitigation.
System cabinets are constructed from ECTFE, PVDF, and FM 4910-certified flame-retardant polypropylene. They feature dual-containment fluid lines, real-time chemical concentration monitoring (±0.05% accuracy), active exhaust scrubbing, and automated dosing to extend bath life safely.
04 What is the typical lead time, installation process, and site acceptance testing (SAT) validation timeline for new fab installations?
Standard equipment lead times range from 16 to 24 weeks depending on tool customization and cleanroom automation integration. Our structured fab deployment protocol follows four synchronized phases:
- Engineering Alignment & FAT (Weeks 1–16): Custom CAD layout verification, chemical line routing planning, tool manufacturing, and Factory Acceptance Testing (FAT) at KOSEN SEMI facilities.
- Delivery & Cleanroom Move-In (Weeks 17–18): Crated cleanroom transport, positioning inside client fab bay, and leveling on isolated vibration pads.
- Hook-Up & Safety Verification (Weeks 19–20): Facility utility hook-up, exhaust balancing, double-containment pressure testing, and SEMI S2/S8 compliance checks.
- Site Acceptance Testing (SAT) & Yield Tuning (Weeks 21–23): Particle count qualification on test wafers, process recipe matching, chemical dispense calibration, and official client sign-off.
