Abstract

Theoretical and experimental studies on the laser annealing of a Si/CoSi2/Si structure are presented. The power absorption in each layer in this structure is theoretically considered using the refractive index and extinction coefficient in CoSi2 and Si, which have been measured by the ellipsometric analysis. Next, an amorphous Si film deposited onto a Si(lll)/CoSi2 structure is annealed by a Q-switched ruby laser. It has been shown from Rutherford backscattering and channeling measurements that the Si film grows epitaxially onto the Si/CoSi2 structure and that an optimum power density to minimize the aligned yield in a Si film 100 nm thick exists around 1.5 J/cm2. Reflecticn electron diffraction and otpical ricroscope analyses are also used to check the crystalline quality and surface structures of the laser-annealed samples.
