Service Advantages

Our competitive edge lies in three uncompromising commitments: precision, flexibility, and sustainability.

Unmatched Accuracy

Our advanced etching systems enable precision manufacturing that exceeds industry standards, including automated chemical baths and fiber laser technology, which continuously minimize the margin of error to the limit. Meanwhile, we also use advanced optical inspection technology.

Rapid Turnaround

Our etching process offers extremely fast processing speeds. Compared with traditional processes, our etching process can achieve rapid response within the expedited timeline while ensuring quality.

Cost Efficiency

The etching process eliminates unnecessary tooling costs and reduces material waste, significantly lowering the production cost per component. This is particularly applicable when you need to produce large quantities of parts.

Service Workflow

We believe in clarity and collaboration—our workflow is designed to keep you informed at every step, from design to delivery.

Consultation & Design Review: Our team of professional engineers will confirm all your project goals with you and propose areas for optimization in your etching design.
Prototype Development: We will first produce a small batch of prototypes to verify the feasibility of the design scheme, and share the relevant inspection report with you, including dimensional measurement data and further confirmation of related performance.
Process Validation: Once the prototype production is problem-free and the process parameters are confirmed, we will proceed with medium-batch production to verify whether the product quality of the etching design scheme remains consistent when the production scale is expanded.
Production & Quality Control: During full-scale production, we conduct automated optical inspections and manual sampling inspections at regular production intervals. We also provide you with real-time production progress updates to ensure transparency throughout the production process.

Arc-enhanced glow discharge ion etching of WC-Co cemented carbide for asymmetric cutting edge preparation of micro milling tools

Arc enhanced glow discharge (AEGD) ion etching, characterized by high ionization degrees and high etch rates, was applied to ultrafine-grained WC-Co cemented carbide, commonly used for micromilling cutters. The effect of AEGD ion etching on the surface integrity of WC-Co and the resulting adhesion behavior of a TiAlSiN thin film was investigated by varying the etching time in comparison with conventional glow discharge (GD) ion etching. AEGD ionic etching is an efficient method to both enhance film adhesion and prepare the appropriate asymmetric cutting edge geometry for micro-milling tools.

FAQs

Q: What types of substrates can be processed through your microfabrication etching services?

A: We support a wide range of materials including silicon, glass, quartz, sapphire, PDMS, PMMA, and other polymer-based substrates. Each etching process is optimized for material compatibility and desired resolution.

Q: Do you offer both wet and dry etching options?

A: Yes. Creative Biolabs provides both wet chemical etching for smooth surface finishes and dry plasma or deep reactive ion etching (DRIE) for high-aspect-ratio microstructures. Our engineers will recommend the best technique based on your design and application.

Q: What is the typical turnaround time for custom etching projects?

A: Turnaround time varies depending on project complexity. Standard single-layer etching projects are usually completed within 2–3 weeks, while multilayer or advanced patterning may require 4–6 weeks. Rush options are available upon request.

Q: How do you ensure the quality and uniformity of etched structures?

A: All etched substrates undergo profilometry, SEM inspection, and surface roughness analysis to confirm dimensional precision and consistency across the wafer. Comprehensive QC reports are provided with every project.

Q: Can you integrate etching with other microfabrication processes?

A: Yes. Our services can be combined with photolithography, thin-film deposition, bonding, and coating to deliver complete microdevice fabrication workflows.
