Abstract
High-transconductance (gm) GaAs FETs and ring oscillators were fabricated using a novel open-tube sulphur diffusion method to form the active layer in a 2 in (51 mm) LEC wafer. Extrinsic transconductances as high as 200 mS/mm were obtained on 2 ¿m-gate FETs. A DCFL ring oscillator, fabricated with 2 ¿m-gate FETs, had 54 ps gate delay at room temperature. This diffusion technique was found to be suitable for GaAs IC fabrication.
