The 14th International Workshop on Junction Technology (IWJT2014) will be held on May 18 - 20, 2014 in Shanghai, China. The IWJT, started in 2000 and was held annually in Japan or China, is an open forum focused on the needs and interest of the community of a junction formation technology in semiconductors. At the past IWJTs, a number of eminent and experienced scientists and engineers from Asia, America, and Europe presented their latest results on junction technology. The workshop will provide a good opportunity for researchers and engineers to present their new research results, and exchange ideas with leading scientists in this field.
