发明名称 METHOD FOR PROCESSING A THIN FILM MICRO DEVICE ON A SUBSTRATE
摘要 A method for processing a thin film micro device on a substrate includes: 1) depositing a carbon film on the substrate as a sacrificial layer; 2) photolithographically defining a first predetermined pattern in the carbon film; 3) etching an unwanted portion of the carbon film outside the first predetermined pattern; 4) depositing a structural film including a single or multiple layers of solid state materials; 5) photolithographically defining a second predetermined pattern in the structural film; 6) etching the discarded portion of the structural film outside the second predetermined pattern; 7) selectively removing the remaining portion of the sacrificial carbon film by using a selective etch process gas in a reactor chamber, so that the overlapped portion of the remaining structural element with the first predetermined pattern is suspended above an underneath cavity above the substrate.
