Abstract :
In this paper, novel device structures in order to realize ultra fast and ultra small silicon devices are investigated using ultra-high vacuum chemical vapor deposition (UHVCVD) and excimer laser annealing (ELA). Based on these fundamental technologies for the deep sub-micron device, high speed and low power devices can be fabricated. These junction formation technologies based on damage-free process for replacing of low energy ion implantation involve solid phase diffusion and vapor phase diffusion. As a result, ultra shallow junction depths by ELA are analyzed to 10~20 nm for arsenic dosage (2×1014/cm2), excimer laser source (λ=248 nm) is KrF, and sheet resistances are measured to 1 kΩ/□ at junction depth of 15 nm
