The saturation mode threshold has been observed to drift as much as ¿0.5V when the MOSFET is operating with high drain voltage. Through a series of experiments it is concluded that this instability is due to a chemical effect associated with hydrogen in the nitride films. The formation of surface states and fixed charges in the channel region due to the-interaction of hot carriers with hydrogen present at the interface is proposed to be the basic mechanism. Experimental results with respect to voltage, time and device geometry, will be discussed.","PeriodicalId":270567,"journal":{"name":"18th International Reliability Physics Symposium","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127480438","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}

{"title":"Reliability Analysis of Several Conductors at High Current Densities for use in Bubble Memories","authors":"M. Shearer, F. Quadri","doi":"10.1109/IRPS.1980.362920","DOIUrl":"https://doi.org/10.1109/IRPS.1980.362920","url":null,"abstract":"Magnetic bubble memories have recently. emerged as production products and are being considered for various applications where non-volatility, modularity and ruggedness are desirable. In order to reduce manufacturing costs, densities have been pushed to the 106 bit/cm2 level with further increases being paced mainly by lithography constraints. Bubble memories require magnetic fields generated by current pulses for various functions such as bubble generation, transfer-in, transfer-out and replication. Among the above-mentioned functions, bubble generation and replication require current amplitudes in the. range of 80mA to 200mA for conductors on the order of 4000 Å in thickness with widths of 2-3¿m. These conditions correspond to current densities of 5 × 106 to 2 × 107A/cm2. As the density of bubble devices increases, the current carrying capacity requirements of the conductors will also increase. Among the prominent causes of failure in conductors carrying high current densities are electromigration and melting due to Joule heating. An associated large temperature rise, due to localized Joule heating, may also give rise to metallurgical reactions in a multimetal metallization,. or chemical reactions with the passivation layer or atmosphere. The major constraint in selecting a conductor system is dictated by the desirability of operating device functions with industrial standards of 5 and 12-volt power supplies. This constraint limits potential metallizations to systems with conductivities better than the Al-4% oCu alloy system. Therefore, conductor choices are limited to Cu, Ag, Au and Al based systems.","PeriodicalId":270567,"journal":{"name":"18th International Reliability Physics Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130778881","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}

It is based on a theoretical analysis which shows that the frequency dependence of the capacitance between a selected pair of IC metallisation tracks can be used to derive the moisture induced component of this capacitance. A measurement on an encapsulated integrated circuit die, held at a constant temperature, is used to determine the ratio of the moisture induced capacitance and the intrinsic capacitance between metallisation tracks. By comparing this ratio with that obtained from a sample of integrated circuits exposed to a known relative humidity, the test can indicate whether the relative humidity in the package is greater or less than a specified value. The accuracy of the test is comparable with that of other moisture sensing methods for encapsulations, and its sensitivity is adequate for the control of known moisture-related failure mechanisms in integrated circuits.","PeriodicalId":270567,"journal":{"name":"18th International Reliability Physics Symposium","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134551393","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}
