It is believed that the first three features that a biological visual system extracts from an object image are edge position, edge orientation and angle position. The contrast edge position of an object and its orientation with respect to the horizontal line can be measured from the active hollow FOur QUadrant Orientation Detector (FOQUOD). Based on this device, a double FOQUOD device which can extract the angle position is proposed for the first time and has been fabricated successfully. The a-Si:H angle position detector is composed of two hollow FOQUODs packed in a concentric fashion and each FOQUOD consists of four a-Si:H p-i-n solar cells.","PeriodicalId":326645,"journal":{"name":"1995 53rd Annual Device Research Conference Digest","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125555005","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}

Device performance of IGBT's has been improved rapidly in recent years, particularly regarding the trade-off between its on-state voltage and switching loss. Another important performance trade-off is between its on-state voltage and short-circuit withstanding capability. A short-circuit condition occurs when an IGBT is fully turned on and the collector-emitter voltage remains high. Since the IGBT experiences both high current and voltage simultaneously, the power dissipation becomes excessive even during a short time period. The IGBT may be destroyed through a latch-up failure mode or simply due to the excessive heat generated in the device. In this paper, a new IGBT structure with emitter ballast resistor is investigated to improve the trade-off between the on-state voltage and the short circuit withstanding capability. IGBTs with voltage and current ratings of 600 V and 5 A have been designed and fabricated to conduct this study. The IGBTs demonstrate excellent switching speed with a typical turn-off fall time of 150 ns. The 3-dimensional semiconductor device simulator DAVINCI is used to model this new design. Both experimental and simulation results are discussed.","PeriodicalId":326645,"journal":{"name":"1995 53rd Annual Device Research Conference Digest","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131491653","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}
