Zusammenfassung: | A semiconductor silicon-germanium thin film preparation method, comprising the following steps: cleaning a mono-crystalline silicon substrate and then disposing the same on a substrate table; respectively sputtering a silicon single thin film and a germanium single thin film; depositing a silicon-germanium alloy thin film having different components on another single crystal silicon substrate using a co-sputtering method, measuring the thickness of the deposited thin film, and obtaining a silicon-germanium alloy thin film having different component ratios. |
