Abstract: PURPOSE: A method of forming a gate electrode having a polycide structure is provided to form a cobalt silicide having a lower resistivity without an etching process by forming the cobalt silicide using an insulating layer of a lower permittivity and a damascene process. CONSTITUTION: A gate oxide layer(22), a layer of a lower permittivity, and an oxide layer for hard masking are sequentially formed on a semiconductor substrate(21).

Abstract: PURPOSE: An optical disk improves recording density and to make correctly reproducible multi-valued data by forming pits having two different depths on a substrate and making the wavelength of the light beams used and the refractive index of an optical disk substrate satisfy a prescribed relationship. CONSTITUTION: Pits having two different depths(D1 and D2) are formed on the substrate of an optical disk. Moreover, the depths are determined so as to satisfy 0<D1 <λ/4n and λ/4n<D2<λ/2n, where λ is the wavelength of the light beams used and n is the refractive index of the substrate of an optical disk. Moreover, the depths(D1 and D2) of the pits are determined so as to satisfy λ/4n<D2<λ/4n and λ /4n<D2<3λ/8n. Then, recorded data are reproduced by combining the signals based on the amount of reflected light beams from the disk and tangential push-pull signals. Since the polarities of the tangential push- pull signals are made differently by the differences in the pit depths, an optical disk having high density three value recording is realized by varying pit depths.

An error computing adder(430) computes an error signal between a pilot signal outputted from the first reverse-spreading unit(420) and a reference pilot signal from an external source. A multiplier(440) multiplies the output of the error computing adder(430) and a gain for controlling an update speed.
