  • Patent number: 10449595
    Abstract: A protrusion forming device includes a holding portion holding an object that is be processed, a tool bit having a cutting portion capable of cutting an object held by a holding portion, and a drive portion capable of driving the tool bit. The tool bit is movable along a cut-in pathway so that the cutting portion is inserted into the object. The cutting portion is movable along a further-cut pathway so as to form a protrusion part that is cut in a linear shape and is connected to the object. The tool bit continuously contacts the protrusion part while moving along a forming pathway such that the protrusion part extends perpendicular to an outer surface of the object.

  • Patent number: 10115567
    Abstract: A plasma processing apparatus can efficiently perform a pulse modulation method of switching a high frequency power to be used in a plasma process between a high level and a low level alternately according to a duty ratio of a modulation pulse. In this plasma processing apparatus, when performing a high/low pulse modulation on the high frequency power for plasma generation, if a weighted variable K is set to be 0.5<K<1, a constant reflection wave power PRH is generated on a high frequency transmission line of a plasma generation system even during a pulse-on period Ton. Meanwhile, during a pulse-off period Toff, a reflection wave power PRL decreases. By adjusting the value of K, a balance between the reflection wave power PRH during the pulse-on period Ton and the reflection wave power PRL during the pulse-off period Toff can be controlled.

  • Patent number: 9793136
    Abstract: A plasma etching method can form a hole having a required opening diameter in a silicon nitride layer, while suppressing a tip end portion of the hole from being narrowed. The plasma etching method includes a first process of supplying a processing gas containing oxygen and fluorocarbon into a plasma processing apparatus; and a second process of etching a silicon nitride layer 106a of a processing target object with a first mask 106 by exciting the processing gas into plasma. Further, the second process is performed in a state where an organic film ad generated from the processing gas is formed on an inner wall of an opening of the first mask 106 by gradually reducing a temperature of the processing target object from a first temperature T1 (80° C.) to a second temperature T2 (40° C.).
