Theory is presented which shows a greatly improved control of both the peak surface and bulk electric fields in reverse biased p-n junctions. Experimental results show breakdown voltages better than 95% of the ideal and at lower leakage current than the corresponding unimplanted devices. For example, diodes with a normal breakdown voltage of 1050 volts with a .5ma leakage current become 1400 volt (1450 ideal) devices with a 5µa leakage current. Applications of the technique are feasible in MOS technology, as would be expected, but are even more attractive in power devices in which the dramatically reduced surface fields are just as important as the extremely high breakdown voltages since it means more flexibility in passivation techniques, two of which we have used to date. Our results have also shown that the implant can be at a variety of temperatures with a good degree of success, extra process flexibility being the goal of these tests.","PeriodicalId":218912,"journal":{"name":"1977 International Electron Devices Meeting","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133177999","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}

The VMOST threshold voltage, breakdown voltage, weak inversion current, junction leakage current, and junction capacitance for both the forward and reverse mode of operation (reversal of source and drain) are experimentally related to the shape of the doping profile throughout the channel.

This combined process named FA-CMOS will be described. The FA-CMOS process is based on the conventional silicon gate CMOS process using the selective oxidation process (SOP) technology. It is necessary to form the avalanche injection region capable of programming with low voltage without the breakdown of N+P-junction ( N+diffusion to P-well region ). Arsenic ions are implanted to form this region and the avalanche injection voltages of less than 20 V are obtained. In addition to the above mentioned process, the double diffusion technology simplifies the formation of source-drain and isolation region. Extremely low power ( 0.6 µW/bit ) PROM was successfully fabricated using the FA-CMOS process.","PeriodicalId":218912,"journal":{"name":"1977 International Electron Devices Meeting","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132145785","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}
