Title: Method and device for plasma etching
Inventor: HORIIKE YASUHIRO
IPC: H01L21/3065
Filed: 1994-09-16
Abstract: PURPOSE: To increase the etching speed ratio and etching characteristics by impressing pulsative high-frequency electric power upon a coil and making the frequency of the high-frequency electric power for generating plasma the same as that of bias power, and then, changing the phase difference between the frequencies of both electric powers. CONSTITUTION: The output of a high-frequency power source 12 is impressed upon a coil 3 through a matching device 7. Then high-density plasma is generated in a reaction chamber 2 by generating helicon waves in the chamber 2. At the same time, the output of a bias power source 10 is impressed upon a planar electrode 5 through another matching device 9. Under such a condition, a workpiece is etched by utilizing a self-bias voltage or AC electric field generated from the electrode 5. When the frequency of pulse modulation is made the same as that impressed upon the electrode 5, the phase difference between both frequencies is appropriately set by means of a phase shifter 13.

The rubbing cloth 12 is thereafter rubbed against the highly conductive stainless steel sheet 15 as well. Then, the dust is rubbed away by the stainless steel sheet 15 even if the miropieces of the oriented film stick as the dust onto the rubbing cloth 12 by friction with the oriented film.  Even if, therefore, the other substrate 4 is subjected to the rubbing treatment, the pickup of the dust and the formation of the flaws on the substrate (oriented film) 4 are prevented and the well oriented state free from defects is obtd.

Abstract: PURPOSE:To make high-precision tracking control possible by multiplexing two carrier waves with a main signal in such arrangement that a tracking error voltage can be detected and recording them and performing a control at a reproducing time so that this tracking error voltage is minimum. CONSTITUTION:One track is divided to a prescribed number of (generally, even) blocks, and for example, a carrier wave Asinomega1t is recorded in every even-numbered block of an A track 11 and every odd-numbered block of a B track 12, and a carrier wave Asinomega2t is recorded in every even-numbered block of a C track 13 and every odd-numbered block of a D track 14, and these four tracks are used as one unit, and hereafter, this arrangement is repeated. In this case, these carrier waves are multiplexed with the main signal and are recorded. At a reproducing time, crosstalk quantities from tracks adjacent to a scanned track are defined as (a) for the carrier wave Asinomega1t and as (b) for the carrier wave Asinomega2t. The direction of tracking deviation of a reproducing head is discriminated by the sign of a voltage (a-b), and the extent of tracking deviation is proportional to ¦a-b¦, and therefore, a servo operation is always performed for (a-b)=0.
