NEW TECH MAY ENABLE DEEPER SILICON USE An innovative technique developed by a Bilkent University team has surpassed current limitations, enabling controlled fabrication of nanostructures buried deep inside silicon wafers with unprecedented control, according to phys . org. The work appears in Nature Communications. The team tackled the dual challenge of complex optical effects within the wafer and the inherent diffraction limit of the laser light. They overcome these by employing a special type of laser pulse, created by an approach called spatial light modulation. The non-diffracting nature of the beam overcomes optical scattering effects that have previously hindered precise energy deposition, inducing extremely small, localized voids inside the wafer. This process is followed by an emergent seeding effect, where preformed subsurface nano-voids establish strong field enhancement around their immediate neighborhood. This new fabrication regime marks an improvement by an order of magnitude over the state-of-the-art, achieving feature sizes down to 100 nm. "Our approach is based on localizing the energy of the laser pulse within a semiconductor material to an extremely small volume, such that one can exploit emergent field enhancement effects analogous to those in plasmonics. This leads to sub-wavelength and multi-dimensional control directly inside the material," explained Prof. Tokel. "We can now fabricate nanophotonic elements buried in silicon, such as nanogratings with high diffraction efficiency and even spectral control." https://lnkd.in/enhtzWyA
