Thesis title: Correlating Local Defects to Global Wafer Properties in Next Generation Semiconductor Platforms
Supervisor: Professor Rik Drummond-Brydson, Professor Andrew Brown

Profile

I started my Ph.D. in the School of Chemical and Process Engineering under Professor Rik Drummond Brydson and Professor Andrew Brown in October 2024.

I pursued my Master's Degree in Materials Science and Engineering at Tsinghua University from September 2021 to June 2024. I worked on ferromagnetic amorphous thin films with high saturation magnetic flux density as my thesis work.

I completed my Bachelor's Degree in Materials Science and Engineering in June 2021 from Qinghai University. My final thesis topic was 'Preparation and Investigation of Low Melting Point Nitrate/Nitrite Molten Salt Mixtures.'

Research interests

I focus on characterising semiconductors at the wafer scale using advanced electron microscopy 4D-STEM capabilities. My work includes investigating defects, interfacial epitaxies, doping profiles and distributions, and lateral uniformities in devices. I seek to correlate these defects with reliability and failure modes, thereby developing metrology methods and enhancing data integration.
