Microfabrication Process Engineer

Open Position

Based at the Micro and Nanofabrication Laboratory at INRS in Varennes, QC, Canada, the successful candidate will work closely with our academic and industrial collaborators to develop and improve custom microfabrication processes. The candidate will also have to travel to other facilities in the Montreal and Eastern Township area, and to AEPONYX’s offices in Montreal.


Develop microfabrication process flows and processes in academic microelectronic foundries.
Troubleshoot fabrication issues with prototypes.
Work with industrial foundries to plan the transfer to mass production of the developed processes.
Any other task associated to the development of the start-up.


The ideal candidate has a master’s or PhD degree with experience in the fabrication of MEMS and/or integrated optical devices. She or he must be able to define fabrication process flows and to troubleshoot fabrication issues. The candidate must also be able to work in a team to accelerate process development. Knowledge of the following processes is required:
  • Reactive Ion Etching (RIE) of silicon and CMOS compatible materials
  • Photolithography
  • Plasma Enhanced Chemical Vapor Deposition (PECVD)
  • Scanning Electron microscopy (SEM)
  • Sputtering

  • Experience with the following is an asset:
    • Electron beam lithography
    • Wafer bonding
    • Low-pressure Chemical Vapor Deposition (LPCVD)
    • Mechanical, optical and electrical material characterization (e.g. stress, refractive index, surface profile, conductivity, etc).
    • Characterization of optical and/or MEMS devices (e.g. propagation losses, spectral response, actuation voltage, frequency response, etc.)

    • The candidate must be able to communicate effectively in English, both orally and in writing. The knowledge of French is an asset.
