Content Summer School

Fundamentals of Vapor-phase Thin Film Deposition

Session 1:

  • Elementary thermodynamics on the physical phases of matter: entropy vs enthalpy
  • Introduction to gas kinetics
  • Transport properties (mass, energy and momentum) in gas phase
  • Introduction to vacuum technology;
  • Deposition from solid source: physical vapor deposition (PVD)
  • On solid-vapor (liquid-vapor) equilibrium and deviation from equilibrium: evaporation and deposition being “the two sides of the same coin

Session 2:

  • The growths of compounds and alloys and the concept of single-phase field
  • Uniformity considerations
  • The types of evaporation sources and rate control fundamentals
  • Dynamics of adatoms
  • The concept of surface energy
  • Nucleation in 2D and 3D
  • Morphological evolution of thin films

Session 3:

  • The growths of single crystals: epitaxy
  • Crystalline defects
  • Chemical vapor deposition (CVD): typical components of a growth system
  • Pros and cons of CVD vs PVD
  • Precursor kinetics
  • Thermodynamic considerations of chemical reactions
  • Reaction rates
  • Different regimes of CVD processes

Session 4 - Selected topics on the application of thin films:

  • Protection film: intrinsic & extrinsic stress, film delamination
  • Semiconductor technology:
    o    Doping profile control considerations, e.g. microwave diodes
    o    Heterostructure, e.g. HBTs: commensurate vs incommensurate
    o    Strained structure fabrication, e.g. Si IC, GaN: misfit strain, dislocation kinetics, etc.
    o    Pertinence to 5G communication

CV Lecturer Ya-Hong Xie

Ya Hong Xie

Ya-Hong Xie (SM’99) obtained the B.Sc. degree in physics from Purdue University, West Lafayette, IN, in 1981, and the M.Sc. and Ph.D. degrees in electrical engineering from the University of California at Los Angeles (UCLA), in 1983 and 1986, respectively.

He was a member of the technical staff in the Physical Sciences and Engineering Research Division, Bell Laboratories from 1986 till 1999. In 1999, he joined the faculty of UCLA as a Professor in the Department of Materials Science and Engineering where he currently serves as vice chair. He has authored and coauthored over 190 technical articles and is the holder of 38 US patents as well as a number of patents of other countries including Korea, Japan and China. His current research interests include plasmon resonance and neural network enabled bio-sensing, and lattice mismatched heterostructures including group III nitrides.

Dr. Xie is a fellow of IEEE. He is the winner of 2012 Research Award of Alexander von Humboldt Foundation and Inventor Recognition Award of Semiconductor Research Corporation. He had been a visiting scientist of IHP, the Leibniz Association Germany Institut für Innovative Mikroelektronik, and is a nominator for the prestigious Japan Prize Foundation. He is an active member of the science and technology community spanning the fields of semiconductor and biomedical. He served as the Chair of the Electronic Materials Committee of IEEE Electron Device Society (2016-2018).
