Then, ammonia (NH3) plasma is employed for the nitridation of HSQ. The effects of NH3 plasma treatments on the high frequency characteristics (100 MHz to 20 GHz) of the interconnect structure Cu/Ta/HSQ are discussed. Among various specimens in this study, the smallest insertion loss is 1.97 dB/mm at 20 GHz for the 400degC- annealed Cu/Ta/HSQ(NH3-plasma-treated for 50 sec). Appropriate NH3-plasma bombardment helps to form a thin SiNx barrier layer which prevents the diffusion of oxygen without increasing the dielectric constant of the Cu-HSQ interconnect system. The dielectric constant of HSQ decreases and then increases with the increase of NH3 plasma treatment time and a minimum dielectric constant of 2.2 is obtained after 50 sec NH3 plasma treatment. Finally, the crosstalk noises among all specimens were measured and the FOM was used to evaluate all specimens.","PeriodicalId":137931,"journal":{"name":"2006 Asia-Pacific Microwave Conference","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132116700","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}

With the introduction of additional internal ports in the filter model, the multi-port admittance-matrix (Y-matrix) is obtained. The main advantage lies in the fact that the filter's basic parameters, as there are the resonant frequency of each resonator, the coupling coefficients and the external Qs are directly accessible through the multi-port Y-matrix. These values are known to give a broad insight into the filter and allow a straightforward optimization procedure to meet the specified data of the synthesis. Furthermore, parasitic effects and design restrictions can be identified and even quantified. Here, an example of a combline filter with a six pole Chebyshev characteristic has been chosen to demonstrate the technique and to verify the method, which can be adapted to other types of filters as well as to other characteristics. Based on this example, a parasitic external coupling was identified and compensated illustrating the advantages of this method.","PeriodicalId":137931,"journal":{"name":"2006 Asia-Pacific Microwave Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132219908","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}
