    Abstract: In a process where a capacitor using a BST film for a dielectric film is incorporated into a DRAM, the film is selectively removed by wet etching for forming a contact hole. For this purpose, a bottom electrode is formed and then an amorphous film is formed on the entire surface of a silicon wafer. And after forming a crystalline top electrode on this film, lamp heating is performed to crystallize only the area that is in contact with the electrode. Then wet etching is performed using a solution of hydrogen and ammonium fluoride (1:2), which allows removing only the amorphous area selectively.

    Abstract: In the fabrication of capacitors, a TiO2 film is formed from a TiN film by means of heat-treatment within an atmosphere which does not contain oxygen. This serves to prevent the polysilicon which forms the bottom electrode from being oxidized during heat-treatment. Thus, once the bottom electrode has been formed on the silicon wafer, a TiN film and RuO2 film are formed, and the silicon wafer is heat-treated in an atmosphere which does not contain oxygen. In this manner, a dielectric film that is a TiO2 film and a top electrode that is a ruthenium film are obtained.

    Abstract: A method for manufacturing a semiconductor device by laminating a plurality of ruthenium-type conductive electrodes and a dielectric film having a perovskite structure, includes forming a first conductive electrode at the semiconductor substrate, forming a first area where elements constituting the first conductive electrodes and elements constituting a first dielectric film are melded, forming a transitional layer by performing a heat treatment on the first meld area within a non-oxidizing atmosphere and forming the first dielectric film on the first conductive electrode. Accordingly, a transitional layer having a consistent composition can be formed with a high degree of efficiency at the interface of the ruthenium-type electrode and the dielectric substance having a perovskite structure, so that a capacitor structure employing a very thin dielectric film having a high dielectric constant can be produced with ease and at low cost.

    Abstract: A second printed wiring board is opposed to a surface of the first printed wiring board. A support member supports the first and second printed wiring boards. A first connector is mounted on the first printed wiring board. A second connector is mounted on the second printed wiring board. A wiring connects the first printed wiring board to the second printed wiring board. The first and second connectors are separately mounted on the first and second printed wiring boards, respectively. The sizes of the first and second printed wiring boards can be reduced as compared with the case where connectors are arranged in a row on a single printed wiring board, for example. This results in a reduction in the size of the printed circuit board unit. A large number of the printed circuit board units can be coupled to the back panel.
