Postdoctoral Researcher on Oxide-oxide CMOS Wafer Bonding for Video Holography

What you will do

Holograms are high-resolution structures that allow to project 3D images in free space. Their resolution is higher than 10000 lines/mm, and their information density surpasses 10 gigabit/cm2. Until recently, one could not image to drive high-quality holograms at video rate due to the limitations in both patterning resolution and data bandwidth. But the silicon industry evolves at warp speed. Pixel densities below 100 nm and data rates above 1 Terabit/s are now within reach, and this opens perspectives to develop video-rate switchable full-color holograms on CMOS driving circuitry. Several physical principles for generating high-speed electrically-addressable holograms are currently investigated. We research a route based on low-power electrical control of the local refractive index of a novel meta-material at the nanometer scale. In the framework of the ERC Advanced Grant video holography, we develop both the metamaterial and the waveguide material independently on separate Silicon wafers in our 300mm CMOS cleanroom.

The goal of this postdoc is to develop the oxide-oxide bonding technology to merge both the metamaterial wafer and the barium titanite (BTO) waveguide wafer, and hence enable the hologram driving. As accurate control of the waveguide is needed on a 100 nm scale, a high-quality interface between both is key. This requires an in-depth insight of the selected oxide interfaces and its wafer to wafer bonding process, and detailed investigation of how this interface can be further improved.

The research will be supported and guided by several experts from different domains in imec:

  • Type of work: 10% literature study, 50% material growth, 40% (optical) characterization
  • Daily supervisor: dr. Robert Gehlhaar (imec, LAE-department)
  • KU Leuven Promotor:  Prof.dr.ir. Jan Genoe (imec, LAE-department  and KULeuven), holder of the video holography Advanced Grant of the European Research Council
