IPC: H01L23/52
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce processes for forming bonding pads and to reduce the damage to an insulating layer as a bed and to a substrate, etc., by simultaneously carrying out the ashing of a mask and the plasma-etching of an upper metal silicide layer and a lower metal silicide layer in the same processing chamber. SOLUTION: A mask pattern is formed of a mask material 15 on an upper metal silicide layer 14, and the upper metal silicide layer 14 is etched. Then, the upper metal silicide layer 14 and a metal layer 13 are plasma-etched leaving a lower metal silicide layer 12. Then, the ashing of the mask material 15 and the plasma-etching of the upper metal silicide layer 14 and the lower metal silicide layer 12 are simultaneously carried out in the same processing chamber. Thus, a dedicated mask and a photolithographic process for forming bonding pads become unnecessary by removing the mask material 15 and the upper metal silicide layer 14 in the same treatment. Further, side etching of the lower metal silicide layer 12 can be reduced largely.

Title: Tape tension controller for tape player
Inventor: YAMASHITA TATSUMA
IPC: G11B15/43
Filed: 1989-01-31
Abstract: PURPOSE:To enable the setting of tension for a magnetic tape without providing a tension arm by detecting a driving current for a driving motor, which varies in accordance with a rotary load of a rotary head device, and giving braking force to a motor for driving a supply side reel base in response to this variation. CONSTITUTION:Contact frictional resistance between a rotary drum of the rotary head device 5 and the magnetic tape T is changed by varying the tape tension, etc., and when the contact frictional resistance is increased, a load of the drum motor Mc is increased, and its motor driving current is increased, and then this motor driving current is converted by an I/V converter 22 into voltage to be given to a reel motor control circuit 23. A current to be given to a reel motor Ma from a motor driving circuit 24 is lowered by the reel motor control circuit 23 in accordance with a rise of a voltage given to this circuit, and hence driving force in the reverse direction by the reel motor Ma is lowered to carry out a control for diminishing the tension. By this method, the tension control is feasible without using any tension arm.
