In these days, when no one is experiencing lack of data, the most valuable thing is the transformation of the data to information. In this paper we would like to present Implant source optimization system (iSOS) which was implemented in Intel HVM facility running Flash NOR technologies at Implant area. The implant area has experienced short source life duration as results of ineffective running mode of operation. This running mode has decreased the tools availability and increased the implant time which has caused lower throughput. In order to improve implant tools availability and utilization a set of \"run rules\" were defined by the area's engineers, utilizing different gases properties to extend the source's life. Though the run rules were well defined it was a difficult task to implement them and monitor the running history. iSOS was designed to transform mass of data from the tools into unique, effective and presentable information. By enabling fast and accurate decision making iSOS enabled Implant area to achieve additional capacity (improved availability by 4%-6%) at lower cost (saving of $10,000 per week) by doubling source life duration.","PeriodicalId":325607,"journal":{"name":"2007 International Symposium on Semiconductor Manufacturing","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133826722","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}

Much of the cost reduction that has been achieved over the last decade can be attributed to the vast productivity enhancement of device geometry reduction. However, further scaling is becoming increasingly complex and expensive; therefore, the semiconductor industry needs new methods for productivity improvement. This paper approaches productivity from the perspective of waste reduction. This new perspective reveals untapped opportunities for productivity improvement. New metrics are defined for evaluating fab waste. These metrics can then be used to quantify the value of potential solutions, as well as to define a roadmap for industry waste reduction.","PeriodicalId":325607,"journal":{"name":"2007 International Symposium on Semiconductor Manufacturing","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123737620","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}

Small water marks formed during wafer drying can be detected as small LPDs just after pre-cleaning. These water marks inhibit SiGe growth during the epitaxial process. In addition, SiGe film LPDs increase drastically with increasing queue time between pre-cleaning process and SiGe CVD process. Finally, SURFimage haze measurement is shown to be a powerful advanced technique to monitor the localized \"abnormal growth defects\" and the surface morphology of the SiGe CVD film over the full wafer surface.","PeriodicalId":325607,"journal":{"name":"2007 International Symposium on Semiconductor Manufacturing","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130295418","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}

We derive a new metric called criticality factor (CF), which is essentially a fractional critical area for a defect of the reported size in a small layout window around the reported defect location. CF would be a good predictor of yield if geometrical considerations alone determined whether an electrical fail will result. Since other properties of the defect affect the electrical outcome (such as material properties), we employ a Training Set of wafers where the functional relation between CF and die yield is learned for each critical inspection step. From that point on these curves are used to predict the yield impact of in-line defects for new wafers. In addition, we show that highly-systematic defects (i.e. layout dependent) deviate from the CF functional curves, and hence add noise to the calculation. We suggest a technique to separate these defects from the random population, and calculate a corrected CF value for them.","PeriodicalId":325607,"journal":{"name":"2007 International Symposium on Semiconductor Manufacturing","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123120180","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}
