One of the steps in the fabrication is the removal of exposed layers in an automatic wet-etch station with chemicals. In time, these chemicals get polluted and their effectiveness decreases. Therefore, the chemicals in these baths need to be renewed or maintained on a regular basis. This can be required after a fixed number of processed wafers, or after a specified period of time. It has been observed in the factory that the wet-etch station can get completely blocked when one of the baths goes into maintenance. This happens when the first batch in queue needs the bath maintained. All subsequent batches then have to wait and the tool is blocked. Placing a different batch in the load lock might have prevented this blockage. In this paper we investigate the influence of the sequence of the batches inserted on the total processing time, when time dependent maintenance is incorporated. In order to do this, a detailed model is constructed based on an actual wet-etch tool. The model parameters were tuned to the values of the actual tool and it was verified that the resulting behaviour was correct. Based on this model a (sub)optimal sequence was constructed. Three sequences were considered: i) an arbitrary sequence, ii) an optimised sequence without considering the time-dependent behaviour of the maintenance, and iii) an optimised sequence with the time-dependent behaviour. It was found that the mean processing time could decrease with about 10% when the time dependent maintenance was incorporated, in comparison with the original, arbitrary, sequence. When a (sub)optimal sequence was constructed without incorporating the time-dependent maintenance, a mean decrease of 4% was realised. This shows that the time-dependent maintenance plays an important role in the total processing time and should be incorporated in the optimisation.","PeriodicalId":80307,"journal":{"name":"The Case manager","volume":"59 1","pages":"1389-1394"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75471065","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}

Ye","doi":"10.1109/CoASE.2013.6653929","DOIUrl":"https://doi.org/10.1109/CoASE.2013.6653929","url":null,"abstract":"This paper presents a new RANSAC based method for extracting planes from 3D range data. The generic RANSAC Plane Extranction (PE) method may over-extract a plane. It may fail in the case of a multi-step scene where the RANSAC process results in multiple inlier patches that form a slant plane straddling the steps. The CC-RANSAC algorithm overcomes the latter limitation if the inlier patches are separate. However, it fails when the inlier patches are connected. A typical scenario is a stairway with a stairwall. In this case the RANSAC plane-fitting produces inlier patches (in the tread, riser and stairwall planes) that connect together to form a plane. The proposed method, called NCC-RANSAC, performs a normal-coherence check to all data points of the inlier patches and removes those points whose normal directions are contradictory to that of the fitted plane. This procedure results in a set of separate inlier patches, each of which is then extended into a plane in its entirety by a recursive plane clustering process. The RANSAC plane-fitting and recursive plane clustering processes are repeated until no more planes are found. A probabilistic model is introduced to predict the success probability of the NCC-RANSAC method and validated with the real data of a 3D camera-SwissRanger SR4000. Experimental results demonstrate that the proposed method extracts more accurate planes with less computational time than the existing RANSAC based methods. The proposed method is intended to be used by a robotic navigational device for the visually impaired for object detection/recognition in indoor environments.","PeriodicalId":80307,"journal":{"name":"The Case manager","volume":"2 1","pages":"261-267"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89260558","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}
