Description of the invention: [Technical field to which the invention pertains] The present invention provides a surface-structured structure and a manufacturing method, and particularly refers to a novel _ material conductor element micro-secret structure and a wire-making method, which can be effectively combined The woven electric junction is difficult to be a semiconductor component, and the structure of the lion's electric ram is improperly eroded and exposed. [Prior Art] According to the current semiconductor MEMS, various micro structures are included, such as: immovable probes, runners, hole structures, or some movable springs, connecting rods, gears (rigid body motion or scratching) Sexual deformation) and other structures. 'Incorporating the above different micro-structures and related semiconductor circuits (for example, c jobs) into each other can constitute various kinds of non-semiconductor turn; the manufacturing method and structural design enhance the micro-mechanical structure of various kinds of Wei, which is the future semiconductor micro The _ indicator of electromechanical systems is also a serious challenge in the future research and development of wafers; if the development of improved techniques can be developed, the future development cannot be predicted. The sensors and actuators currently fabricated in microelectromechanical devices (MEMS) are manufactured independently of semiconductor components (eg, CMOS) and require a floating structure on the germanium substrate; the aforementioned processes must be advanced. Semiconductor technology, such as wet money engraving, dry remnant and sacrificial_layer removal, etc. _s : MiCr〇-EleCtro-Mechanical ^mems); the aforementioned wet surname is a health The etchant is effective and does not cause the etchant of the material. Therefore, wet etching usually has a relatively high selectivity for different materials. As for the engraving (electricity, engraving) Partial solution _ gas to carry out, the biggest advantage of cognac is anisotropic etching (anisotropic etching). However, the above-mentioned prior art has several problems as follows: - - Regardless of the side mode, the micro-electromechanical farm (MEMS) and semiconductor components (for example, CM〇s) are separately produced, and the two processes are Incompatible with the whole °' can only be produced separately in the ic pre-process, and then connected to the IC after the process is compatible with the second, so the resulting parasitic effect and the material will make the cost high, and will increase In the future, the complexity of the county; second, wet etching will not only etch in the longitudinal direction, but also have a horizontal money engraving effect; lateral remnant will lead to the so-called "edge money" (imdeixut) defects; second, dry etching It can be anisotropically etched, but the selectivity of dryness is lower than that of wet money. The development of the aforementioned technology is very rapid. In order to improve the problems of the etched technology, the U.S. Patent No. 6 '712 '983B2 proposes a technique using Reactive I〇n Etching (IE). Although technology 7 1360177 can greatly reduce the undercut phenomenon, but because it is also from the top to the bottom of the layer of money engraving, and the last time the Shi Xi base a lot of engraving work must use the horizontal 働 i skills Lai's _ _ technology furnace is too numb complicated, and multiple etching processes will pass through the MEMS structure, this MEMS structure in the implementation of a large number of side and horizontal butterfly ship capacity # will have fiber phenomenon ((four) hit cut) What is important is that the problem of exposure and affecting yield after the completion of the electromechanical structure process has not been improved.
