It is found that nanosecond UV laser annealing can be successfully applied to rebuild a perfect monocrystalline SOI layer and reach arsenic activation levels at least as high as rapid thermal processing, with a reasonably large process window. Thanks to electrical and morphological characterizations, the defective or polycrystalline silicon obtained below the optimum range is evidenced, as well as the loss of monocrystalline nature of the silicon at the upper end of the process window.","PeriodicalId":117665,"journal":{"name":"2016 16th International Workshop on Junction Technology (IWJT)","volume":" 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132124904","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}

Detectable defects are monovacancies to vacancy clusters, and there is no restriction of sample temperature or conductivity. Using this technique, we studied defects introduced by Mg-implantation in GaN. Mg ions of multiple energies (15-180 keV) were implanted to provide a 200-nm-deep box profile with Mg concentration of 4×10<sup>19</sup> cm<sup>-3</sup>. The major defect species of vacancies introduced by Mg-implantation was a complex between Ga-vacancy (V<sub>Ga</sub>) and nitrogen vacancies (V<sub>N</sub>s). After annealing above 1000°C, these defects started to agglomerate, and the major defect species became (V<sub>Ga</sub>)<sub>2</sub> coupled with V<sub>N</sub>s. The depth distribution of vacancy-type defects agreed well with that of implanted Mg, and no large change in the distribution was observed up to 1300°C annealing.","PeriodicalId":117665,"journal":{"name":"2016 16th International Workshop on Junction Technology (IWJT)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124305150","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}

Initially, we evaluated the benefits of beamline ion implantation in replacement of diffusion anneal doping process. Two different annealing routines were studied. The first one using a single annealing to activate both B implanted emitter and P implanted BSF, while the second one used two different annealing to separately activate each dopant. Good yield was reached with a record cell of 20.33% efficiency. Secondly, we investigated the doping by plasma immersion ion implantation where the final objective was the fabrication of a solar cell fully doped by plasma. BF3 and B2H6 were compared as precursor gases for the boron emitter doping, while PH3 was used for the BSF doping. Hybrid cells were fabricated using both implantation techniques and a maximum efficiency of 19.8% was obtained.

N-type PH3 plasma assisted doping was characterized by dopant diffusion and electrical activation with increasing wafer temperature. Plasma assisted doping at high wafer temperature showed no structure damage even at a high incident energy condition with a bias power applied to the wafer, while a shallow junction of less than 7nm of Xj formation was achieved with low incident energy condition without bias power. Adding a silicon surface modification step when using the decoupled plasma condition prior to PH3 doping was found to enhance the dopant level and lower Rs dramatically.

After reaching the limit, we cannot expect such a big progress as the past for electron devices in terms of cost, performance and energy consumption. Then, the effort will be focused to develop various kind of electron devices such as new memory, sensors, power, photovoltaic, battery and MEMS devices which are demanded for IoT era.
