講座內容:

    The micro-semiconductor industry has ever since the inception, been confronted with the deposition of thinner films. These films are accompanied by some exceptional attributes to meet the requirement for the manufacture components with desired durability, efficiency and performance. The industry has, however, sort after atomic   depositions (ALD) which has so far proven capable of depositing quality nano-films of superb features. These features are of utmost importance for advanced technology and to achieve optimized efficient products that require pin-hole-free, uniform, conformal and accurate thickness control. It is necessary to continually fathom and refined the knowledge of the fabrication process. The research endeavour within this field is studied by collaboration of Prof TC Jen and his team of researchers. The aim of understanding the thin film process of ALD is studied within the reactor to feature scale. The continuum, lattice Boltzmann, density function theory, molecular dynamics are utilized to numerical model the numerous phenomena inside the reactors and thin film features. This keynote reports on the current findings of the numerous research endeavours. This includes the behaviour and optimization of geometrical designs, ALD recipe refinements, velocity and exposure time phenomena, the chemical kinetics hypothesis, and the way forward in ALD numerical investigations.
