Abstract:
1. A method of fabricating a micro electro mechanical system switch, comprising: depositing a metal layer on a substrate and patterning signal lines comprising switching contact points and immovable electrodes; depositing a sacrificial layer on the signal lines and the immovable electrodes; depositing a second sacrificial on the first sacrificial layer and forming contacting member holes in positions facing the switching contact points; depositing a contacting member layer on the second sacrificial layer and leaving portions of the contacting member layer buried in the contacting member holes to pattern contacting members; depositing an actuating member layer on an upper surface of the contacting member layer on which the contacting members are formed and patterning inner and outer actuating members; depositing a third sacrificial layer on the second sacrificial layer on which the inner and outer actuating members are formed and patterning gap forming parts forming gaps of pushing rods; depositing a fourth sacrificial layer on the third sacrificial layer and patterning pushing rod support holes; depositing a pushing rod layer on the fourth sacrificial layer and patterning the pushing rods; and removing the first, second, third, and fourth sacrificial layers.
