    摘要: In a semiconductor device having a mark opening portion such as an alignment mark and an overlay mark, a BPSG film formed by patterning on this mark opening portion interposing a first conductive film is covered by a second conductive film; and the BPSG film serves as a core of a cylindrical storage node and is removed after the second conductive film is formed in a shape of sidewall by a vapor phase HF treatment process, whereby a conductive contaminant is not peeled off at the time of removing the BPSG film, wherein a drop of yield can be restricted.

    摘要: A portion of a cell plate 91 extending upon a field oxide film 107a and a silicon oxide film 123 is referred to as a lower layer interconnection film 109. The lower layer interconnection film 109 has a concave shape. A through hole 95a is formed in a silicon oxide film 93 reaching the bottom of the concave shape lower layer interconnection film 109. The depth of the through hole 95a is greater in comparison with the case where a through hole is formed on an upper face portion 123a of the silicon oxide film 123. Because the depth of through hole 95a is great, the thickness of the tungsten film 101a formed in through hole 95a becomes thicker. This eliminates the problem that all the tungsten film 101a in the through hole 95a, and then a portion of the lower layer interconnection film 109 are overetched. Therefore, electrical connection between the upper layer interconnection layer 103a and the lower layer interconnection layer 109 can be ensured.

    摘要: In a semiconductor device, a connection conductive layer is formed by patterning on a p-type semiconductor substrate. A silicon nitride film is formed on the connection conductive layer with an insulating layer. A silicon oxide film is formed on the silicon nitride film. The silicon oxide film is provided with a hole. The silicon nitride film is exposed at a bottom of the hole. The hole is located immediately above the connection conductive layer. Thereby, a thickness of the insulating layer on a fuse element which can be blown can be controlled easily in the semiconductor device.

    摘要: A keyboard device for an electronic musical instrument comprises a keyboard chassis, keys rotatively arranged on the keyboard chassis, and a key switch arranged beneath each of the keys for detecting a key status of each key. Each key has a switch-depressing projection arranged just above the key switch, and a hammer-depressing projection for depressing a hammer when the hammer is provided, with the switch-depressing projection and the hammer-depressing projection being formed adjacent to each other in one piece.
