Project Experience

Lithography Simulation Software Development

2022/05 - Present Hefei Xiangyun Huizhi Technology Co., Ltd.

In the field of integrated circuits, lithography technology transfers designed patterns to wafers. The actual patterns on wafers usually deviate from designed patterns. Simulation of the lithography process helps understand the source of deviation and perform quantitative compensation. The project completed the encoding and decoding of lithography machine internal files, established lithography exposure, development, and etching models, planned to design experiments to assist clients in extracting model parameters, simulated critical dimensions of lithography, and optimized the objective function characterizing lithography quality to achieve quantitative compensation.

My role: Communicating with clients to determine requirements, formulating R&D plans, software implementation, and progress communication.

PET Physical Simulation and Image Reconstruction Software Development

2020/10 - 2022/04 Hefei Xiangyun Huizhi Technology Co., Ltd.

Positron Emission Tomography (PET) is one of the effective tools for early tumor screening. The project developed physical simulation software and image reconstruction software for PET equipment design assistance, and used this software to complete client prototype equipment evaluation testing and improvement. The physical simulation software simulated isotope decay, positron-electron annihilation, photon scattering, and photoelectric absorption based on Monte Carlo methods, achieving simulated data collection for arbitrary detector structure designs. The image reconstruction software reconstructed collected signals back into three-dimensional images of isotope concentration distribution, and improved contrast and eliminated artifacts through various image correction methods.

My role: Formulating development plans, algorithm design and verification, software implementation, MPI multi-process parallel and OpenACC GPU acceleration, and technical document writing. Assisted colleagues in acceleration performance analysis and optimization. Responsible for data processing and analysis in test contracts, as well as project stage reports.

Deep Ultraviolet LED R&D

2018/04 - 2020/08 Hefei Rainbow Blue Light Technology Co., Ltd.

AlGaN-based deep ultraviolet LED solid-state light sources convert electricity into deep ultraviolet light for sterilization and disinfection. They have the characteristics of high customization, easy integration and control, and good stability. Compared with mature GaN-based materials, AlGaN-based materials have strong chemical bonds, deep impurity levels, and high epitaxy difficulty. The project continuously improved the brightness, yield, and life of deep ultraviolet LEDs by customizing and modifying epitaxy equipment, designing energy band structures, controlling doping and defects, and optimizing epitaxy windows.

My role: Participated in the entire process of equipment modification, epitaxy process window search, energy band structure design, and theoretical understanding of impurity defect formation control during project development. The project started mass production in 2020, and I was responsible for formulating and implementing R&D directions. 2 related authorized invention patents.
