0.05-µm-Gate InAlAs/InGaAs HEMT and Reduction of Its Short-Channel Effects

In this paper, how the world's top-level high-frequency characteristics were achieved through the development of a lattice-matched InAlAs/InGaAs high-electron-mobility transistor (HEMT) on an InP substrate with a T-shaped gate was described. The design guidelines based on systematic investigations of the short-channel device structure were also presented.

In the early 1990s when this paper was published, the InAlAs/InGaAs HEMT on an InP substrate was expected to become a key device in 40 Gbps optical communications systems or millimeter-wave wireless communications. This is because it had promising high-speed/high-frequency characteristics that surpassed those of Si or GaAs devices. Thus, to improve these characteristics, the scaling down of the device was intensively studied. It was reported that the high-frequency characteristics required for a 40 Gbps optical communications system could be achieved by using a pseudomorphic InAlAs/InGaAs HEMT on an InP substrate with a gate length reduced by 0.05 µm. However, the breakdown voltage of this pseudomorphic HEMT was low. Therefore, the application of the device was severely limited, and it was difficult to apply it to the logic circuits of 40 Gbps optical communications systems.

In this paper, the fabrication of lattice-matched InAlAs/InGaAs HEMTs on an InP substrate with excellent breakdown voltage characteristics and gate lengths of 0.5 to 0.05 µm, and the systematic investigation of the immunity to the short-channel effect with respect to the design of the channel layer and the barrier layer were reported. Consequently, the use of a lattice-matched HEMT with a gate length of 0.05 µm was found to result in a current gain cutoff frequency of 300 GHz and a maximum oscillation frequency of 235 GHz, which are comparable to those of pseudomorphic HEMTs.

Since the device technology reported in this paper demonstrated that both breakdown voltage and high-frequency characteristics can be attained simultaneously, it has been used as a basic technology of integrated circuits for optical communications and opened the door to the practical application of 40 Gbps optical communications.

On the basis of the above, the great contribution of this paper to industry and academia is recognized. We here present this SSDM Award in honor of its value.
