摘要: 介绍了基于光刻机的150 nm T型栅GaAs PHEMT工艺,其中重点介绍了使用的shrink关键工艺步骤。利用新工艺在某100 mm GaAs工艺线上进行流片,并通过直流测试、loadpull测试、微波小信号测试以及环境试验、极限电压测试、高温步进试验,获得新工艺下制作的GaAs PHEMT的各项性能指标及可靠性。最后制作得到的器件在性能和通过直接光刻得到的PHEMT在性能和可靠性上基本在一个水平上,但是想要通过shrink工艺得到线宽更细的栅长需要进一步努力。

Abstract: The paper introduces the process of 150 nm T-shaped gate GaAs PHEMT and highlights key steps including shrink technology.The GaAs PHEMT is taped out in 100 mm GaAs process.The GaAs PHEMT goes through the DC measurement,loadpull measurement,microwave small signal measurement and environmental test,limit voltage measurement and high temperature step test and obtain the performance parameters and reliability.The performance and reliability of the device obtained by the developed process are similar with the ones obtained by direct lithography.The fabrication of thinner gate length through the shrink process is still a long way to go.

Key words: GaAs, PHEMT, reliability, T-shaped Gate
