摘要： In a semiconductor device manufacturing method, a first insulating film is formed on a semiconductor substrate. A contact hole is selectively formed in the first insulating film. A first conductive film is formed on the first insulating film to fill the interior of the contact hole. A second insulating film is formed on the first conductive film. A second conductive film is formed on the second insulating film. The second insulating film and the second conductive film are patterned to leave the second insulating film and the second conductive film only immediately above the contact hole. A third conductive film is formed on the surfaces of the first conductive film, the second insulating film, and the second conductive film. The third conductive film on the first and second conductive films is removed to form a cylindrical lower electrode consisting of the third conductive film left only on the side surfaces of the second insulating film and the second conductive film. An exposed portion of the first conductive film and the second conductive film are removed to expose the first and second insulating films. The second insulating film is removed to expose the first conductive film. A third insulating film and a fourth insulating film serving as an upper electrode are formed.

摘要： In addition to microwave and excitation light, bias light as well is irradiated upon a surface of a semiconductor sample that is passivated using a solution which contains an electrolyte. Irradiation of the bias light increases the quantity of ionic substances that exist in the solution, largely changes a surface potential of the semiconductor sample, and suppresses surface recombination. This makes it possible to measure the lifetime of carriers which exist within the semiconductor sample at a high accuracy, without influenced by surface recombination.

摘要： An attempt was made to increase the film thickness of at least a portion of word lines over which a storage node electrode of the capacitor for storing charges extends in a DRAM having word lines, bit lines and memory cells comprising one transistor and one stacked capacitor for charge storage. This increases the surface area of the storage node electrode. This also increases the opposing areas of the storage node electrode and the cell plate electrode of the capacitor for storing charges. This invention realizes the increase in the surface area of the storage node electrode without imposing additional burden on processibility.
