Ohmic Contact Formation

In this work, pulsed-laser-based tempering was applied for post-implant annealing of n-type N-doped 4H-SiC in order to electrically activate the dopants and to rebuild the crystal structure. The annealing was performed by a frequency-tripled Nd:YVO4 laser with a pulse duration of 60 ns. To evaluate the effects of post-implant annealing, JBS diodes were electrically characterized. The results were compared with implanted, not post-annealed JBS diodes. The electrical measurements showed a significant on-state voltage drop of 40 mV at 6 A for post-implant laser annealed diodes compared to not post-implant annealed diodes.

Recent strong demands for optoelectronic communication and portable telephones have encouraged engineers to develop optoelectronic devices, microwave devices, and high-speed devices using heterostructural compound semiconductors. Although the compound crystal growth techniques had reached at a level to control the compositional stoichiometry and crystal defects on a nearly atomic scale by the advanced techniques such as molecular beam epitaxy and metal organic chemical vapor deposition techniques, development of ohmic contact materials (which play a key role to inject external electric current from the metals to the semiconductors) was still on a trial-and-error basis. Our research efforts have been focused to develop, low resistance, refractory ohmic contact materials using the deposition and annealing techniques for n-GaAs, p-ZnSe, InP, p-SiC p-CdTe etc. It was found the growth of homo- or hetero–epitaxial intermediate semiconductor layers (ISL) was essential for low resistance contact formation. The importance of hetero-structural ISL was given taking an example of n-type ohmic contact for GaAs.
