Semiconductor Wet Etch Spray Nozzles: Product Overview
Wet etching is among the most chemically aggressive manufacturing environments in precision manufacturing.
- Orifice geometry: the spray performance foundationReview threads, bores and sealing surfaces and functional requirements before defining the process.
- Flow channel uniformity and particle cleanlinessReview threads, bores and sealing surfaces and functional requirements before defining the process.
- Fluoropolymer precision machining as a material-specific competencyPTFE's CTE is 10× higher than aluminum (100–125 ppm/°C); its modulus 140× lower.

Why CNCPioneer for Semiconductor Wet Etch Spray Nozzles?
Coordinate geometry, material, finishing and inspection around the part's intended function.
Orifice Geometry and Inspection
Specify orifice diameter, length, entry form and burr acceptance. Review available tool access and the agreed measuring method for the nozzle's smallest features.
Process Chemical Compatibility
Provide the process chemistry, concentration and operating temperature with the selected material. The equipment designer must confirm compatibility before a machining substitution is approved.
Spray Pattern Verification as a Nozzle Quality Discipline
Agree critical-feature checks, measuring methods and inspection records with your drawing.
Nozzle Pattern and Mounting
Define each nozzle type by outlet pattern, mounting thread and orientation. Identify spray or flow testing separately from the dimensional inspection of the machined part.

Explore representative configurations and share your drawing for a product-specific review.
Fan Spray (Flat Fan) Nozzles
Fan spray nozzles produce a flat, sheet-like spray pattern through a precision-machined V-groove or elliptical orifice.
Full Cone Spray Nozzles
Full cone spray nozzles produce solid circular spray patterns through a swirl-and-orifice design: swirl insert bore ±0.010mm; swirl channel tangential entry angle ±1°; main orifice bore ±0.005mm, Ra 0.1μm; exit cone angle ±0.5°; cone half-angles 15°, 30°, 60°, 90°, 120° standard.
Hollow Cone Spray Nozzles
Hollow cone nozzles produce an annular spray pattern — fluid concentrated at the cone periphery with minimal fluid at the center — through high-swirl-number tangential entry geometry that throws fluid to the periphery by centrifugal force.
Two-Fluid (Air-Assist) Atomizing Nozzles
Two-fluid atomizing nozzles use compressed nitrogen or CDA to atomize liquid etchant into fine droplets (SMD 10–100μm, versus 200–500μm for pressure-only nozzles) for gentle low-impact chemical delivery to delicate wafer surfaces.
Ultrasonic Nozzle Bodies
Ultrasonic spray nozzles use piezoelectric transducer vibration at 25–180 kHz to atomize liquid into ultra-fine mist (SMD 15–100μm) without compressed gas or high liquid pressure.
Multi-Orifice Array & Zone-Spray Nozzles
Multi-orifice array nozzles integrate multiple orifices in one nozzle body for wider spray coverage in a compact footprint.
