摘要： The present invention relates to the manufacture of a semiconductor switch for use in a variety of communication systems, and particularly to the manufacture of a RF micro-machined switch of pull-up type, wherein an electrostatic electrode is used so as to cause the contact pad involved in the operation of the switch to be pulled upward from below.The RF micro-machined switch of pull-up type according to the invention has a high isolation characteristic for shorting and opening the circuit and needs a low driving voltage, so that miniaturization of communication system is possible because a circuit for booting driving voltage is not required within the system. Further, the characteristic of switch is little changed after a long use because the metal composing the contact pad experiences little deformation during operation, whereby the semi-permanent use of switch is possible.The present invention provides a pull-up type RF micro-machined switch, wherein the shorting of the contact pad with the transmission lines is possible with a low DC voltage by altering the conventional pull-down type electrostatic electrode into a pull-up structure and the opening of the circuit is facilitated by the weight of the contact pad by composing the contact pad in a thick metal layer.

摘要： A method of fabricating a two-terminal semiconductor component using a trench technique is disclosed that includes forming a trench by etching an etching pattern formed on a substrate on which an active layer having impurities added is grown, forming a front metal layer on a front upper surface of the substrate by using an evaporation method or a sputtering method after removing the etching pattern, forming a metal plated layer on the front surface of the substrate on which the front metal layer is formed, polishing a lower surface of the substrate by using at least one of a mechanical polishing method and a chemical polishing method until the front metal layer is exposed, forming a rear metal layer on the polished substrate, and removing each component by using at least one of a dry etching method and a wet etching method.
