Title: Manufacture of semiconductor device
Inventor: MAEDA SATORU
IPC: H01L21/8242
Filed: 1984-06-20
Abstract: PURPOSE:To prevent the generation of an acute angle section in a capacitor groove, and to keep the withstanding voltage of an insulating film in a capacitor by a method wherein a cylindrical groove is formed to a first insulating film, a first conduction type semiconductor layer is deposited in the groove, a recessed groove is shaped at the center of the first conduction type semiconductor layer and a trench capacitor is formed by utilizing the recessed groove. CONSTITUTION:An SiO2 film 102 formed onto a semiconductor substrate 101 is used, the film 102 is etched up to the surface of the substrate 101 to shape ring- shaped grooves 105 employing the inner-diameter size of a trench-capacitor groove as an inner diameter, P type silicon is deposited 106 in the grooves 105, and SiO2 at the center of the grooves is removed through etching, thus forming a recessed groove 108 for a trench-capacitor. Accordingly, SiO2 at the center of the groove fills the role such as a core for a mold, and acute angle sections as seen in conventional devices are not shaped to the bottom section A of the groove of the trench-capacitor and the surface section B of a single crystal silicon layer in the capacitor formed after removing SiO2 at the center of the grooves through etching, thus relaxing the concentration of an electric field at a corner section, then preventing the lowering of the withstanding voltage of the insulating film.
