The structure is based on a planar capacitor design where low-k film is deposited after the patterning of the capacitor, followed by metallization and Cu CMP. This so called low-k planar capacitor structure provides several unique capabilities to study various aspects of barrier/low-k TDDB compared with the conventional damascene structures. Two of the unique capabilities are presented in this paper. First, TDDB from a damage-free low-k material has been measured for the first time using the low-k planar capacitor structure. Second, the test structure is sensitive enough to quantify the impact of selected process conditions, such as barrier re-sputter and plasma treatments, on TDDB.","PeriodicalId":345860,"journal":{"name":"2009 IEEE International Reliability Physics Symposium","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116131395","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}

First, we present the reliability mechanisms and progress on the previously reported GaN HEMTs. Next, we introduce our specific device structure for GaN HEMTs for improving reliability. An n-GaN cap and optimized buffer layer are used to realize high efficiency and high reliability by suppressing current collapse and quiescent current (Idsq)-drift. Finally, we propose a new device process around the gate electrode for further improvement of reliability. Preventing gate edge silicidation leads to reduced gate leakage current and suppression of initial degradation in a DC-stress test under high-temperature and high-voltage conditions. Gate edge engineering plays a key role in reducing the gate leakage current and improving reliability.","PeriodicalId":345860,"journal":{"name":"2009 IEEE International Reliability Physics Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130039323","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}
