IPC: G03G15/04
Filed: 1990-01-29
Abstract: PURPOSE:To restrain the fluctuation of light output by arranging the incident surface of an optical element so that it may not be orthogonally crossed with the optical axis of a light beam. CONSTITUTION:After the light beam projected from a semiconductor laser 1 is collimated by a collimating lens 2, it is made incident on one surface of a polygon mirror 3. The light beam deflected by the rotation of the mirror 3 is formed into an image as a fine spot on a recording surface 5 by an ftheta lens 4 and performs scanning with the rotation of the mirror 3. Since an ND filter 7 functioning as the optical element which is positioned on the optical axis 6 of the collimated light beam and has a light quantity adjusting function is provided, the light quantity of the light beam projected from the laser 1 is attenuated to a desired one by transmitting the light beam through the filter 7. By providing the filter 7 so that the incident surface of the filter 7 may not be orthogonally crossed with the optical axis 6 of the light beam, the light quantity returned to the laser 1 is adjusted to be decreased with the aid of the inclination quantity theta and the fluctuation of the light output is restrained.

Filed: 1988-02-01
Abstract: PURPOSE:To obtain a semiconductor device which can be operated at high speed by a method wherein one or more nitrided refractory metal layers are formed and an electrode wiring layer constituted by a polysilicon layer and a silicide layer is made to be more stable low-resistance wiring layer. CONSTITUTION:A titanium nitride layer 6a between a polycrystalline silicon layer 4 doped with a high-concentration impurity and a silicide layer 5 functions to restrain the impurity from being diffused from the polycrystalline silicon layer 4 to the silicide layer 5. In addition, a tintanium nitride layer 6 formed on the silicide layer is used as a barrier material to prevent a reaction with aluminum, copper or the like to be used as a wiring material. By this setup, an electrode wiring part constituted by the polycrystalline silicon layer 4 and the silicide layer 5 is made to be a wiring layer whose contact resistance is low; because an interface between the individual layers is stabilized, the reliability of the electrode wiring part is enhanced. When a highly integrated circuit is to be manufactured, a high-temperature heat-treatment operation to be served also as a reflow operation of an interlayer film is required. Because, even with this high-temperature heat-treatment operation, it is possible to restrain the impurity in polycrystalline silicon from being diffused, the high-temperature heat- treatment operation can be executed.
