    • A negative hole is formed by etching a dielectric layer that includes at least a lower dielectric sublayer and an upper dielectric sublayer. The lower dielectric sublayer and the upper dielectric sublayer have substantially the same permittivity, and the lower dielectric sublayer may have a higher etching rate lower than the upper dielectric sublayer. The negative hole formed in the upper and lower dielectric sublayers has an etched profile with a protruded portion protruding from at least the boundary between the lower dielectric sublayer and the upper dielectric sublayer. With various embodiments of the disclosed invention, resistance between the cathode and the gate may be secured to prevent arc generation and signal distortion.
    • 通过蚀刻包括至少下电介质层和上电介质层的介电层形成负孔。 下电介质子层和上电介质子层具有基本上相同的介电常数,并且下电介质子层可以具有比上电介质子层低的蚀刻速率。 形成在上下电介质子层中的负孔具有蚀刻轮廓,其具有从至少下电介质子层和上电介质子层之间的边界突出的突出部分。 利用所公开的发明的各种实施例,可以确保阴极和栅极之间的电阻以防止电弧产生和信号失真。

    • Disclosed is a diamond tool having a metal plate inserted therein. Between abrasive layers containing diamond particles is inserted a ferrous or non-ferrous metal plate having a wear resistance lower than that of the abrasive layers such that a concave groove is spontaneously formed during a cutting process, thereby reducing the contact load with a workpiece to thereby avoid vibration (wobbling) of a shank, and providing a discharge path for smoothly removing cutting chips and the cooling water. In addition, the content of abrasives and the wear resistance of bonding material are uniformly constituted so that the shrinkage rate does not need to be considered during sintering and the manufacturing process can be simplified, thereby reducing the manufacturing cost and improving the productivity therefor. Furthermore, the area of the metal plate can be controlled, thereby enabling an easy design conforming to the working conditions with a workpiece.
    • 公开了一种金刚石工具,其中插入有金属板。 在含有金刚石颗粒的研磨层之间插入耐磨性低于研磨层的耐磨性的铁或非铁金属板,使得在切割过程中自发形成凹槽,从而减少与工件的接触载荷 避免柄的振动(摆动),并且提供用于平滑地去除切屑和冷却水的排出路径。 此外,研磨剂的含量和接合材料的耐磨性均匀地构成,使得在烧结期间不需要考虑收缩率,并且可以简化制造过程,从而降低制造成本并提高其生产率。 此外,可以控制金属板的面积,从而能够使与工件的工作条件相一致的简单设计。
