Two kinds of material are considered: conventional (copper) and innovative (carbon nanotubes).

Simple but physically-meaningful models for carbon nanotubes are proposed, based on the concept of the number of conducting channel and on the evaluation of the mean free path. The comparison between the materials is made with reference to a 30 μm-pitch pillar bump, proposed as chip-to-package interconnect.","PeriodicalId":293987,"journal":{"name":"2010 IEEE 14th Workshop on Signal Propagation on Interconnects","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130475014","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}

While this technique brings a slight improvement in accuracy over previous ones, its main strength is a greater degree of generality. With a modeling approach less dependent on the nature of the devices and more easily extendable to include the effects of multiple inputs one may hope better meet the challenges of advancing technology. The proposed models can be obtained from device port transient responses only and can be easily implemented in any simulation environment, including SPICE-based circuit description software. Two illustrative examples conclude the paper.","PeriodicalId":293987,"journal":{"name":"2010 IEEE 14th Workshop on Signal Propagation on Interconnects","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128037549","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}

The effect of different plane assignments is studied and the results are validated with a general purpose full-wave solver. It is shown that the plane configuration affects mainly the coupling into the parallel-plate mode, and it could be either a broadband or narrowband effect depending on the link environment. Although the effect of ground vias can be appreciated with any plane configuration, the utilization of more ground planes helps to reduce the equivalent parallel-plate impedance and therefore to decrease the amount of energy coupled between the reference planes. A reduction of up to 1.8 dB of the transmission and an increase of more than 10 dB of the crosstalk could be observed at specific frequencies when the assignment of a single reference plane was changed from ground to power.","PeriodicalId":293987,"journal":{"name":"2010 IEEE 14th Workshop on Signal Propagation on Interconnects","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133133631","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}

But crosstalk and delay performance are degraded with interconnect length. So designers can use large drivers with fast response to compensate global falloff due to long interconnects with critical delay and crosstalk levels. They must also trade off IC's cost and consumption against performance. The present study proposes to relax interconnect density requirement in some dedicated intermediate metal level of the Back End Of Line (BEOL). By doing this, delay and crosstalk level due interconnect itself are consequently reduced whatever the driver size. This solution is especially beneficial to long interconnect alleviating IC's design constraints.","PeriodicalId":293987,"journal":{"name":"2010 IEEE 14th Workshop on Signal Propagation on Interconnects","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117311016","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 was found that at data rates above several Gbps, the skin effect causes eye parameters in the digital domain to deteriorate in response to interconnect damage well before the creation of an open circuit. Fatigue tests were conducted to gradually stress a solder joint while monitoring changes to the eye parameters, including rise time, eye height, jitter, and the constituent components of jitter. All of these parameters were found to exhibit measurable degradation prior to complete separation of the solder joint. The jitter component making the largest contribution to the change in total jitter was intersymbol interference. The results support the conclusions from prior studies using time domain reflectometry and demonstrate their implications for digital electronics. Digital signal parameters offer an improved means of interconnect reliability assessment compared to traditional methods using DC resistance. The eye parameters also provide interconnect failure precursors, which may be useful as a product health monitoring tool for high speed electronics.","PeriodicalId":293987,"journal":{"name":"2010 IEEE 14th Workshop on Signal Propagation on Interconnects","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126030873","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}
