METHOD FOR MAKING IMPROVED LSCO STACK ELECTRODE

摘要

A method for making an improved LSCO stack in the generation of platinum features on the surface of a substrate. The method provides an inexpensive means for depositing and etching LSCO material in the construction of small platinum features. The method comprises sputtering of the LSCO material and utilizing a photoresist mask to pattern the LSCO in accordance with the platinum features. The problems and expense associated with high-temperature deposition of LSCO on platinum and the etching thereof are overcome by sputtering the LSCO at room temperature.
