Abstract:
A method of fabricating a device, comprising the steps of:(a) fabricating a standoff on a substrate;(b) positioning a shadow mask in a first position over the substrate by placing the shadow mask onto the standoff;(c) performing a first process on the substrate through the shadow mask;(d) after performing the first process, moving the shadow mask to a second position over the substrate, wherein the second position is measured relative to the first position; and(e) after moving the shadow mask to a second position, performing a second process on the substrate through the shadow mask; wherein a first charge is applied to the standoff and a second charge having a polarity opposite to that of the first charge is applied to the shadow mask, during a step selected from the group consisting of step (c) and step (e), to facilitate intimate contact between the standoff and the shadow mask during the selected step.
