Abstract:
A method for making a microactuator comprising providing a first substrate and a second substrate facing each other with a distance and movable with respect to each other, and providing a first comb electrode having a plurality of first comb elements formed on an inner surface of the first substrate and a second comb electrode having a plurality of second comb elements formed on an inner surface of the second substrate;wherein a wafer comprising two substrate layers and an interlayer provided therebetween is used as any one of the first substrate and the second substrate and one of the two substrate layers is etched using a mask having a predetermined pattern to form a first electrode precursor group and a second electrode precursor group for the first electrodes and the second electrodes, respectively, the interlayer below any one of the first and second electrode precursor groups is removed by etching to form any unconnected one of the first and second electrodes and to form the other one of the first and second electrodes supported by connecting films formed by etching of the remaining interlayer, and said unconnected one is bonded to the other one of the first substrate and the second substrate.
