Latest Patents

Liao's latest patents include the development of an ultrathin silicon oxynitride interface material and a modified tunnel oxide layer. The ultrathin silicon oxynitride interface material is an SiON film with a thickness ranging from 1 nm to 4 nm, containing nitrogen atoms at a concentration of 1% to 40%. This innovative material significantly reduces the diffusion rate of boron, thereby minimizing its damaging effects and improving the integrity of the SiON film. Additionally, the SiON film's energy band structure is similar to that of silicon nitride, which enhances hole transport efficiency and reduces contact resistivity.

Another significant patent involves a modified tunnel oxide layer and a TOPCon structure. The modified tunnel oxide layer is subjected to plasma surface treatment, resulting in a silicon oxide layer with a silicon content greater than or equal to 18%. This treatment decreases the density of interface states and effectively reduces boron's damaging effects on the tunnel oxide layer, thereby improving the overall performance of the TOPCon structure.
