Test structures do not adequately represent the product in terms of feature diversity and feature volume, and therefore are unable to identify all the systematic defects that will affect a product over its manufacturing lifetime. This paper describes a comprehensive methodology that addresses the prevention and identification of systematic defects. For prevention, a method called RADAR (Rule Assessment of Defect-Affected Regions) has been developed for measuring the effectiveness of design-for-manufacturability (DFM) rules in preventing systematic defects that is based on volume diagnosis data. A second method called LASIC (Layout Analysis for Systematic Identification using Clustering), also based on volume diagnosis data, has been developed for identifying systematic defects that escape DFM. To validate RADAR and LASIC, a fast and accurate defect simulation framework called SLIDER (Simulation of Layout-Injected Defects for Electrical Responses) has been developed. SLIDER generates virtual failure data with known defect characteristics. Experiments involving two industrial chips and virtual failure data from SLIDER demonstrate the effectiveness of RADAR and LASIC.","PeriodicalId":260931,"journal":{"name":"2011 IEEE International Test Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114638439","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}

In “2.5D” Stacked ICs (2.5D-SICs), multiple dies without TSVs are stacked side-by-side on top of a passive silicon interposer base containing TSVs. In true 3D-SICs, multiple dies containing TSVs themselves are vertically stacked; one or multiple of such stacks are possibly placed on a passive silicon interposer. This paper proposes a post-bond test and design-for-test (DfT) strategy for 2.5D- and 3D-SICs containing a passive silicon interposer base. Functional interconnects in the interposer are reused as much as possible in order to keep the interposer cost low.","PeriodicalId":260931,"journal":{"name":"2011 IEEE International Test Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115024939","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}

This paper presents a method to simultaneously reduce test data volume and test power utilizing clock gating. This is achieved through not clocking a high proportion of scan chains during both scan shift and test response capture. Reducing the number of scan chains shifted during scan load can be expected to permit higher scan shift frequency thus reducing the test time. Reduced test data volume can be expected to permit fewer tester channels for testing which can increase the number of chips tested in parallel. Experimental results presented for industrial circuits demonstrate that on average a factor of 1.98 and 4 reductions in test data volume and test power, respectively is achievable using the proposed method.","PeriodicalId":260931,"journal":{"name":"2011 IEEE International Test Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132376359","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}

Limitations exist, however, such as the low Multi-Site Efficiency of analog mixed signal tests and the high system price for large pin count devices. Concurrent Test has been implemented to reduce the test time. This test strategy is difficult to implement without the DFT design of the device. The authors introduced the concept of Multi-Domain Test at VTS 2011 and explained that this Multi-Domain Test solves the aforementioned problems and limitations of Multi-Site Test and Concurrent Test. The authors also showed that the COT of Multi-Domain Test is lower than that of Multi-Site Test for high-end SOC devices. This Multi-Domain Test was applied to a mixed signal SOC. Although the Multi-Site Efficiency of the Dual-Site Test was more than 97%, the COT of the Dual-Domain Test was approximately 10% lower than that of the Dual-Site Test.","PeriodicalId":260931,"journal":{"name":"2011 IEEE International Test Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128802274","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}

State-of-the-art board-level diagnostic software is unable to cope with high complexity and ever-increasing clock frequencies, and the identification of the root cause of failure on a board is a major problem today. Ambiguous or incorrect repair suggestions lead to long debug times and even wrong repair actions, which significantly increases the repair cost and adversely impacts yield. We propose a smart diagnosis method based on artificial neural networks that can learn from repair history and accurately localize the root cause of a failure. Fine-grained fault syndromes extracted from failure logs and the corresponding repair actions are used to train the neural network. The proposed network structure is simple, it can be rapidly trained, and it is scalable to large datasets. Moreover, the relationship between typical syndromes and the most appropriate repair actions can be easily inferred from the network structure. An industrial board, which is currently in production, is used to validate the diagnosis approach in terms of diagnostic accuracy, resolution, and quantifiable improvement over current diagnostic software.","PeriodicalId":260931,"journal":{"name":"2011 IEEE International Test Conference","volume":"13 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131575347","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}
