Publication number: 20150237770Abstract: An electromagnetic shielding tube has a resin inner layer as the innermost layer, a resin outer layer as the outermost layer, and a metal metal-layer between the inner layer and the outer layer. The bonding strength between the outer layer and the metal layer is made weaker with respect to the bonding strength between the inner layer and the metal layer. For example, while an adhesive layer is provided between the inner layer and the metal layer, the outer layer can be directly extrusion coated onto the metal layer without providing an adhesive layer or the like between the outer layer and the metal layer.Type: ApplicationFiled: February 26, 2015Publication date: August 20, 2015Inventors: Masanori YAMASAKI, Tatsuya YUASA, Yoshiyuki HIRAYAMA, Nobuaki SAKAI, Naoko OMORI, Masakazu KOZAWA, Takuro YAMADA, Manabu KOJIMA

Patent number: 6958279Abstract: A gate insulator film and a gate electrode are formed on a semiconductor substrate, and then a layered stack of a SiO2 film and a SiN film is formed on the entire surface. Subsequently, sidewalls made of polysilicon film are formed adjacent to the gate electrode via the layered stack of the SiO2 film and the SiN film. Then, using as a mask the gate electrode, portions of the layered stack adjacent to the gate electrode, and the sidewalls, an ion dopant is implanted into a device active region to thereby form source/drains therein, and the sidewalls are then removed. At this stage, since the gate insulator film is completely covered with the layered stack, the gate insulator film is not ablated or retreated even on a device isolation insulator film.Type: GrantFiled: August 18, 2003Date of Patent: October 25, 2005Assignee: Fujitsu LimitedInventor: Manabu Kojima
