The actual size of chamber can be much smaller than the size of microdischarge cavities pattern, in some cases .., as long as microdischarge cavities show, to micro-
The size of cavity is less demanding, at this point it is possible to using photoresist as mask;Under other occasions, to the size of microdischarge cavities
It is required that higher, then the reticule layer of photoresist+relatively thin can be used to be used as mask, first, utilize micro- sky in photoresist
Chamber pattern come graphical reticule layer so that reticule layer has microdischarge cavities pattern, then using anti-reticule layer come
Etch raised T, because reticule layer is relatively thin with respect to photoresist, so as to ensure the microdischarge cavities size that is obtained in raised Y with
The size of microdischarge cavities pattern in anti-reflecting layer is close, too many without reducing.Here, the thickness of reticule layer is preferable
1~2 times of the size of microdischarge cavities is formed needed for being arranged to.
