The traditional wafer fab layout is known to industrial engineers as a job shop. The strength of the job shop system is excellent process flexibility. Job shop layouts also cause long cycle times, lesser quality, and poor communication between workers. A workcell based wafer fab addresses some of those weaknesses. This paper presents initial results of the implant masking workcell in a development fab.","PeriodicalId":114928,"journal":{"name":"International Symposium on Semiconductor Manufacturing, Extended Abstracts of ISSM","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116419720","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 new measurement method made it possible to measure the moisture molecule concentrations adsorbed on solid surfaces exposed to the atmosphere having high moisture concentrations. It has been found that the amount of adsorbed moisture molecule concentrations on solid surfaces in the atmosphere with 1% at 25 C is 2.5x1016 molecules/cm 2 in equilibrium.","PeriodicalId":114928,"journal":{"name":"International Symposium on Semiconductor Manufacturing, Extended Abstracts of ISSM","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127216095","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}
