Precision Deposition
Successful lithography depends on the absolute uniformity and adhesion of the photoresist layer. Nanofilm utilizes advanced spin-coating techniques to deliver defect-free, high-resolution coatings tailored to your specific etching and exposure requirements.
Advanced Spin-Coating Technology
Our deposition process is engineered to overcome common lithographic challenges, such as adhesion failure and uneven etching. By utilizing a precision spin technique, we ensure a fringeless application, eliminating edge-bead interference and providing a perfectly level surface for your mask aligner or stepper.
- Adhesion Optimization: Over decades of collaboration with leading semiconductor and optical firms, we have refined our surface preparation protocols to ensure maximum resist bonding, even on complex metallic thin films.
- Uniformity Control: Our process guarantees consistent thickness across the entire clear aperture, ensuring predictable exposure energy requirements for your facility.
Thermal Stability & Softbake Standards
To ensure the resist arrives in an optimally stable state, every substrate undergoes a controlled softbake at 103°C for 30 minutes. This critical step:
- Removes residual solvents from the film.
- Stabilizes the resist layer for transit and storage.
- Minimizes dark film loss during your development process.
Quality Assurance & Protection
Each coated substrate is individually inspected by our technical staff under specialized safelight conditions to ensure a zero-defect surface.
- Cleanroom Packaging: Products are hermetically sealed in UV-protected, light-tight containers to prevent accidental exposure and contamination.
- Ready-to-Use: Our photoresist blanks are delivered fully stabilized and ready for immediate placement in your cleanroom workflow.
