The Vertical Integration Advantage

Millar specializes in end-to-end MEMS pressure and pH sensor design, fabrication, integration, and low- to mid-volume manufacturing. Our in-house microfoundry delivers both off-the-shelf and custom solutions, and provides a faster, more seamless path from concept to fully integrated device.

Fabrication to Final Product All Under One Roof

At our pure-play MEMS microfoundry, we leverage decades of experience to craft high-fidelity MEMS sensors tailored to our customers’ needs. Our portfolio includes a variety of ISFET pH sensors, Wheatstone half and full-bridge pressure sensors, and more. Every step of the production process, from lithography to chemical vapor deposition, diffusion and annealing, is carefully performed in-house. Once our wafers pass testing, our operators meticulously dice and pick them. Our state-of-the-art facilities include a dedicated testing factory, a fully equipped tooling shop featuring a five-axis CNC milling machine, an electronic and PCB circuit design facility, a dynamic software development unit, and a comprehensive sensor and product assembly facility.

Chemical Vapor Deposition (CVD)

With CVD, we grow thin films of materials with exceptional purity and uniformity. This process is vital for creating sensor layers with precise thickness and characteristics, ensuring optimal sensor performance.

Diffusion / Annealing Furnaces

Our diffusion and annealing furnaces optimize sensor properties such as conductivity and stability. This step ensures that sensors exhibit consistent and reliable behavior across various applications.

Vacuum Deposition

Through vacuum deposition, we apply protective layers to sensors, enhancing their durability and resilience. This process is crucial for shielding sensors from environmental factors and ensuring long-term functionality.
