ABSTRACTIn this work was investigated a simple laser doping method employing doped oxide glass films as dopant source (up to 2.1021cm−3) which are deposited onto silicon by the spin coating technique. Both short (20 ns) and long (200 ns) pulse duration excimer laser beams were used to deposit a large amount of energy in a short time onto the near-surface region. Under suitable conditions, the irradiation leads to surface melting and dopant incorporation by liquid phase diffusion from the surface. Boron distribution profiles in the two pulses duration regimes were studied as well as their electrical properties, and the junction formation of less than 20 nm in depth was demonstrated.

We developed a novel KrF excimer laser doping system for 4H-SiC power devices, and demonstrated laser doping of 4H-SiC with Al thin film deposited on the surface. As seen from the results of the Al depth profile, high concentration implantation (~ 1021 cm-3 at the surface) of Al was achieved by laser ablation of the Al thin film. A high, built-in-potential (~3.5 V) of the pn junction diode was clearly seen in the I-V curve. In addition, the contact resistivity of the deposited Al/Ti electrodes on the surface was 1.9 × 10−4 Ωcm2 by TLM (Transmission Line Model). It was confirmed that a high concentration of Al doping and low contact resistivity were achieved by the KrF excimer laser doping system.
