The fabrication of the transistors is based on the process flow developed by \"TIGER\" for HEMT epitaxy on SiC bulk substrates. The obtained results show the capabilities of such composite devices, providing HEMT device electrical and small signal microwave performance similar to those obtained currently on bulk single crystal SiC substrates.

In conventional approaches, the parasitic network is described by a proper topology of lumped elements. As an alternative, a distributed description of the parasitic network can be conveniently adopted. In particular, the latter solution is the better choice when dealing with device scaling and very high operating frequencies. In this paper the parasitic network is described by means of a suitable distributed network identified through electromagnetic simulations of the device layout. It is shown how the adoption of a distributed instead of a lumped description leads to a more accurate equivalent-circuit-based electron device model. The good scalability properties of the approach are also presented through experimental results.","PeriodicalId":436391,"journal":{"name":"2007 European Microwave Integrated Circuit Conference","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133175137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
