(Title): Laser Precision Engineering from Microprocessing to Nanofabrication

(Speaker):Professor hong minghui

(Time)June 10, 2019, 9:30am

(Venue) X9511, Xipu Campus ,SWJTU

Outline of the Talk:

Laser precision engineering has unique eases as a non-contact process with flexible setup and high speed processing in air, vacuum or liquid environment. In the last decades, We have witnessed its extensive applications in the fields from academic researches to production lines. In this talk, Our research progress on dynamic laser-materials interaction and the signal diagnostics in real time will be reviewed. How to achieve small heat affected zone (HAZ) is a key issue in high quality Laser micro-processing and nano-manufacturing. Hybrid laser processing can lead to laser precision engineering of difficultly processing substrates, To the as heat sensitive and ultra - thin substrate devices. The Optimization of laser - materials interaction can dojo.provide us will approaches to overcome optical diffraction limit for sub - where surface Patterning. Combined with the advanced AFM and NSOM means, laser processing resolution can be pushed down to sub - 50 nm. To solve the technical bottleneck of missile laser nanoprocessing, Parallel (multi-beam) and maskless laser processing techniques are developed. Potential and challenges of laser-materials interaction to cater for 22nm and beyond based on laser produced plasma (LPP) EUV light source and flexible laser manipulation of atom deposition for atomic engineering will also be discussed.
