Abstract | The statistical design of experiments technique was used to study the influence of junction formation process variables on the diffusion sheet resistance. A two-level screening experiment with 2/sup 3/ factorial design was used to evaluate three process variables in eight combination runs. The factors were BF/sub 2/ and Ar implantation dose, drive-in temperature and drive-in time. Variance analysis was used to analyze the data and we found that all of the main variables were important for arsenic implanted wafers but only the drive-in temperature factor was important for boron implanted wafers. We also discovered that there was no significant interaction between the factors. For arsenic implanted wafers, which were driven-in at 950/spl deg/C, the measured sheet resistances were at between 110 and 130 /spl Omega///spl square/ while for wafers which were driven-in at 850/spl deg/C, the sheet resistances were measured at between 60 and 90 /spl Omega///spl square/. For boron implanted wafers, the measured sheet resistance values were found to be constant at about 30 /spl Omega///spl square/, regardless of drive-in temperature. The experimental data were used in regression equations to model the sheet resistance. By this, we have illustrated how the statistical design of experiments methodology can be used effectively in order to control the process performance. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
