MEMS technologies are often developed on four-inch and six-inch silicon wafers. Novati Technologies provides advanced development capabilities on a foundry-compatible eight-inch equipment set, allowing more dies per wafer and lower cost per die. The eight-inch silicon platform enables concurrent integration of MEMS technology with CMOS technology.

Novati helps accelerate development and commercialization of MEMS technologies, including:

  • Cantilever-based devices
  • Sealed cavity devices
  • Sensors with high-aspect features
  • Devices with unique material requirements and/or low thermal budgets

Bonding

  • Anodic bonding for glass lid-wafer attach
  • Eutectic metal bonding for hermetic cavities
  • DBI bonding for 3D electrical interconnect

Bosch Etch

  • Industry-leading Bosch-etch capability powered by the latest tools
    • Achieve 25:1 aspect ratios with ease

Films

  • Advanced film support for MEMS devices, with the ability to deposit high-quality films up to 10um thick
  • Full stress-tuning capability for both high-temperature (350C+) and low temp (down to 125C) films

Microfluidics is a key enabling technology for today’s most innovative lab-on-a-chip (LoC) applications, which are revolutionizing the life sciences industry. Microfluidics technology integrates assay operations like detection, sample pre-treatment, and sample preparation on one chip.

Novati helps companies accelerate development and commercialization of LoC products. The technology drivers for these products include nano-scale microfluidic channel sizes, smart sensing, and integration with signal processing — all requiring integration with CMOS.

Sacrificial Materials

  • Multiple polyimide processes to help build large fluidic channels and cavities
  • Demonstrated success with the fill of high-aspect cavities using photo-imagable films
    • And the planarization thereof
  • Large cavity formation using sacrificial polyimides
  • Established process modules for thick-film dep, etc. and CMP

Electrode Materials

  • Gold-free, subtractively patterned bio-compatible electrodes (e.g. Platinum)

Transparent Substrates

  • Fully capable FEoL and BEoL process suite for transparent substrates (e.g. quartz)

Nanowires & Nanochannels

  • 193nm (dry) lithography and spacer-based technologies to enable sub-45nm devices

Leverage Novati’s Integrated Sensor Platform to bond a sensor wafer to CMOS or take advantage of our diverse materials capability to develop a custom sensor that suits your high precision application.

ESD Protection

  • Proven ability to build ultra-sensitive devices such as PiN diodes through robust ESD protection procedures

Flex-Fab

  • Bond wafers from different foundries/technologies to create novel devices
  • Novati is fab-agnostic, and works with most major foundries (“split-fab”)

Integrated Sensor Platform

  • Leverage our split-fab manufacturing infrastructure and technology integration modules
  • Custom sensor development and integration

As a critical component of key subsystems in optical network systems, photonic planar lightwave circuits (PLCs) enable superior performance but are challenging and costly to develop and manufacture. By partnering with Novati, customers can increase the output of current silicon and quartz-based products, while accelerating the development of new PLC concepts.

Optical waveguide PLC fabrication processes are an extension of CMOS and MEMS processing technology where core lithography, etch, and thin-films technologies apply. Process control of line widths, sidewall roughness, refractive-index uniformity, film thickness, and stress are all key in optimizing device performance.

Most CMOS semiconductor foundries can only handle a small selection of materials. Novati makes novel materials standard. We utilize an Element Review Board (ERB) to enable safe and efficient introduction of any new materials into our facilities.
