|Polyethylene terephthalate (PET) is often used as a substrate for flexible electronic devices. However, PET cannot be easily etched to form membranes for device applications. In the past, etching was done using laser ablation, which is expensive and can only etch very small areas.
Purdue University researchers have developed a new method for etching PET, which is cost effective and useful for etching large areas. This technology allows for the etching and precise shaping of PET. It combines the use of several technologies to create an effective procedure for creating PET devices.
-Enables large areas to be etched
-More cost effective than laser ablation
