Silicon Photonics STED Plasma Dispersion Effect Super-Resolved Imaging in Silicon

The Problem

The silicon industry is currently heading toward 10 nm technology in integrated circuits. Promoting this market trend is largely dependent on the development of super-resolution in silicon microscopy.

The Solution

We propose a novel method that provides the ability to probe the silicon under surface in super-resolution.
More specifically, we developed a new concept for beam shaping of an IR probe laser beam in the silicon by a second pump laser beam in the visible, absorbed in the silicon. The pump beam creates photo-charges that block the IR beam according to the lateral shape of the pump beam via the plasma dispersion effect. The pump beam could be either in a sharp Gaussian shape that induces a hole in the center of the IR probe beam or the pump beam is in a donut shape that blocked the IR beam while living a sharpen beam in its center.

The Commercial Benefit

Our cutting-edge, unique innovative method:

  • Serves as an extremely important tool in the field of nanoelectronics such ICs failure analysis
  • Induces higher spatial frequencies and allowed super- resolution
  • Is similar to the STED technique in fluorescence microscopy
  • Can be applied in other semiconductors

Market Potential
