A semiconductor device and method for fabricating a semiconductor device yields improved doping efficiency and increased capacitance. The method includes forming a silicon film on a substrate. HSG having a spherical projection forms on a surface of the silicon film. The surface of the silicon film having the HSG is washed, and a lower electrode forms by a doping process. A dielectric film and an upper electrode are sequentially formed on the silicon film without washing.

A novel E. coli (KCCM 10,013) which can produce high yields of L-phenylalanine and a method for production of L-phenylalanine by recombinant E. coli which may be transformed with a novel plasmid pMW16 containing two promoters and a temperature-sensitive repressor for expressing a pheA gene and an aroF gene wherein chorismate mutase p-prephenate dehydratase is coded for by the pheA gene and 3-deoxy-D-arabinoheptulosonate.7-phosphate synthase is coded for by the aroF gene.
