  • Abstract
    The high-temperature stability of sputtered tantalum silicide contacts on gallium arsenide has been evaluated. Diodes consisting of Ta silicide on epitaxial n (1.9 × 1017 cm¿3; 0.23 ¿m/n+ GaAs substrate were annealed at temperatures from 375°C to 800°C. Result show that the ideality factor, barrier height and reverse breakdown voltage remain stable at value of 1.1, 0.79 V and 9 V, respectively. MESFETs with Ta silicide gates exhibited similar drain current/voltage characteristics as conventional Cr/Au gate devices.
