  • Publication number: 20100062606
    Abstract: The object of the present invention is to provide a dry etching method by which generation of a notch in an insulating layer can be suppressed and highly-accurate microfabrication can be realized. In a dry etching method according to the present invention, a substrate in which a semiconductor layer is formed on an insulating layer formed of a silicon oxide is prepared, a through-hole is formed in the semiconductor layer, and a resin film is formed on side walls of the through-hole and a recessed portion while forming the recessed portion in the insulating layer by etching an area in which the insulating layer is exposed via the through-hole. By forming the resin film on the side wall of the recessed portion, the side wall of the recessed portion is protected from collision of ions in plasma and generation of a notch in the recessed-portion side wall is suppressed.

  • Publication number: 20090277873
    Abstract: The object of the present invention is to provide a dry etching method which permits the reduction of the amount of any etching product formed during the etching process to thus improve the in-plane etching uniformity with respect to an object to be etched. The dry etching method comprises the steps of providing an electrode equipped with an electrode-presser member which at least comprises a surface layer composed of an yttrium-containing oxide and which is disposed on the peripheral region of the upper surface of the electrode, placing a substrate on the electrode and then subjecting the substrate to dry etching, while preventing the formation of any etching product at the peripheral region of the electrode.

  • Publication number: 20090102025
    Abstract: A method for manufacturing a semiconductor device comprises dry-etching a thin film using a resist mask carrying patterns in which at least one of the width of each pattern and the space between neighboring two patterns ranges from 32 to 130 nm using a halogenated carbon-containing compound gas with the halogen being at least two members selected from the group consisting of F, I and Br. The ratio of at least one of I and Br is not more than 26% of the total amount of the halogen atoms as expressed in terms of the atomic compositional ratio to transfer the patterns onto the thin film. Such etching of a thin film avoids causing damage to the resist mask used. The resulting thin film carrying the transferred patterns is used as a mask for subjecting the underlying material to dry-etching.

  • Patent number: 5543854
    Abstract: A video signal processing apparatus, video signal recording/reproduction apparatus, and method therefor, perform arithmetic operations upon an input video signal and the input signal delayed by a predetermined amount of time. A memory stores the input signal for the predetermined amount of time in order to produce the delayed input video signal. A controller controls the memory to store the input video signal for the predetermined amount of time based on a main synchronization signal. A first synchronization signal is produced by separating a synchronizing signal from the input video signal. A second synchronization signal is generated based on the first synchronization signal. During operation, a switching unit supplies the first synchronization signal to the controller as the main synchronization signal until the second synchronization signal becomes synchronized with the first synchronization signal.
