Title: Plasma etching method
Inventor: NISHIBE HARUHITO
IPC: H01L21/3065
Filed: 1987-02-10
Abstract: PURPOSE:To cut down etching period as well as to prevent the adhesion of an organic polymer in a contact window by a method wherein, when the contact window is going to be formed on the dielectric layer located on an Al wiring, the mixture of hydrocarbon gas containing fluoric atoms and sulphur fluoride gas is plasma-excited, and the dielectric layer and a TiN layer are etched. CONSTITUTION:A contact window 57, with which the surface of an AI wiring pattern 52 is exposed penetrating the TiN layer 53, is formed on an Si oxide dielectric layer 51 formed on the Al wiring pattern 52 having a TiN layer 53 on its upper surface. In the formation of the above-mentioned window, a small quantity of sulphur fluoride reaction gas of about 10% having strong etching property against TiN is mixed in the hydrocarbon reaction gas containing fluoric atoms to be used for plasma etching performed on the dielectric layer 51. As a result, the etching rate on the TiN layer can be increased sharply without impairing the etching rate on the dielectric layer 51, the adhesion of organic polymer on the material to be etched while it is being etched can be stopped, and the lowering of etching rate due to the organic polymer can also be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent an ink leak from occurring by attaching a cup-shaped elastic sealed cylinder to the interior of a cap, then bringing an almost orthogonal collar with the axial center of a mouthpiece mounted on an opening in a shaft cylinder into tight contact with the open end part of the sealed cylinder when the cap is placed over the shaft cylinder, and hermetically closing a tip part including an air hole on the shaft cylinder side. SOLUTION: A cap 13 is placed at a specified position with a shaft cylinder 1 by engaging the contact stepped part 17 of plural ribs 16 provided on the inner wall of the cap 13 with the collar part 11 of a mouthpiece 10 fitted tightly into a shaft cylinder 1. In addition, an engaging stepped part 18 is formed on the ribs 16 of the cap 13, then the stepped part 20 of a cup-like rubber sealed cylinder 19 is butted against the engaging stepped part 18 and in turn, is fitted into the ribs 16 and engaged with a specified position in the cap 13. Further, the open edge part 21 of the sealed cylinder 19 is slightly projected from the contact stepped part 17 of the cap 13, and the cap 13 is placed over the open edge part 21 of the sealed cylinder 19.  If the collar part 11 comes into contact with the contact stepped part 17 of the ribs 16 of the cap 13, the open edge part 21 of the seal rubber 19 is compressed to come into close contact with the collar part 11 of the mouthpiece 10, and an air hole 12 and a pen point 9 are hermetically sealed.

Abstract: PROBLEM TO BE SOLVED: To provide a simple ultrasonic atomizing device for atomizing a liquid by providing a bar-shaped supporting section for supporting a pair of plate-shaped metal vibrators respectively and atomizing a liquid out of a channel. SOLUTION: Plate-shaped balancing vibrators A1 and B2 are provided by bonding piezoelectric ceramic A group 3-D group 6 for bending vibration excitation with a metal plate-shaped medium, and disposed in parallel and as close as possible one another, and very small channels 7 are formed between the vibrators to form an integral structure. When homologous signals are applied to piezoelectric ceramic A group, 3-D group 6, standing waves are generated and the displacement of standing waves are generated in the plate-shaped balancing vibrators A1 and B2, and the suction of air and jetting of liquid are carried out alternately between channels 7, and pressure (radiation pressure) is applied to sucked air in the channels 7 formed at very small intervals, and simultaneously, sucked liquid is jetted out of the channels 7.  At this time, as the vibrators are vibrated with high-frequency, the liquid in the misty form is jetted out of the jet opening of the channels 7. As the reduction and deterioration of resonance and the phase adjustment of input signals are not required and the air radiation pressure can be generated easily in a device, the constitution can be simplified and thinned easily.

Abstract: PURPOSE:To prevent an original from getting under a gate member and always securely distinguish a feeding original from a returned original by providing said gate member which is vertically movable at a defined angle to said original. CONSTITUTION:When the end of an original is detected by a stack sensor, a driving source 17 is operated so as to lower a gate member 7. At this time, a pin 14 projected out of a shaft 11 for supporting a gate lever 12 is rotated to a position sufficiently separated from the gate lever 12. Accordingly, the gate member 7 can always press the top face of the originals downward by its own weight irrespective of the quantity of the originals. Also, the gate member 7 the bottom edge of which has a comb-teeth form, together with the top face ribs 3a of an original stacker 3, presses the originals against a paper feeding belt 21 while giving a wave form to the originals. Originals which are discharged onto the original stacker 3 hit against the gate member 7 and are arranged for the following feeding. In this case, since the bottom edge of the gate member 7 has the comb-teeth form, the documents are prevented from getting under the gate member 7.
