Title: Method for lowering reflectivity of substrate surface
Inventor: IIMURA KATSUHIKO
IPC: G03F1/46
Filed: 1992-09-28
Abstract: PURPOSE:To lower the reflectivity on the surface of a substrate by directly subjecting a titanium nitride film deposited on a substrate in order to lower the reflectivity to an oxygen plasma treatment by using a device, such as asher to be used for a resist ashing treatment. CONSTITUTION:The titanium nitride film deposited on the substrate is subjected to the oxygen plasma treatment, by which the surface of the titanium nitride film is oxidized. The surface reflectivity is further lowered by an increase in interference effect. The probable reason thereof lies in that the TiOxNy is formed on the front layer of the titanium nitride film (TiN) deposited on the substrate. This TiOxNy serves an effective antireflection film. After the metallic film is formed by sputtering on the semiconductor substrate, the titanium nitride film having 1000Angstrom  film thickness is formed by sputtering in such a manner that the reflectivity is confined within a specified range. The results obtd. by subjecting this evaluating substrate to the oxygen plasma treatment under prescribed conditions are then shown in Fig. The reflectivity is lowered from 21.6% down to 16.6% according to the results of such experiment.

This illumination light is emitted with high luminance mainly toward the periphery in the front surface direction and has a proper spread in a propagation direction. The appearance of the patterns is suppressed to the extent of making the patterns invisible even when the glittering surface 302 is directly observed.

Abstract: PURPOSE:To secure a desired printing speed, by determining a current offset value through calculating an average value of currents supplied to a DC motor at the time of an operation for determining an origin for printing positions, and controlling variations in printing speed by supplying the current offset value at the time of a normal printing operation. CONSTITUTION:A controlling CPU 1 is connected, through a bus 9, with a ROM 2 storing a control program, a RAM 3 for storing control information, a DA converter 4 for driving a DC motor 6 by converting a digital quantity commanded by the CPU 1 into a current, and a speed-detecting circuit 5 measuring the time interval of variations in a signal from a photosensor 8. At the time of determination of an origin for printing positions which is performed immediately after a power source is switched ON, a carriage is moved at a predetermined target velocity over a predetermined distance, and a dynamic frictional offset value is obtained by averaging the values written into the DA converter during the movement. The dynamic frictional offset value is added to an output from an amplifier, whereby it is possible to control the rotating speed of the DC motor, namely, the velocity of the carriage to a fixed value, and a desired printing speed can be secured.
