Filed: 1998-06-11
Granted: 2000-06-21
Abstract: This discovery aims to provide an effective method to detect the silicon wafer contamination level. Based on metals' affinity to oxide film, the test procedure as shown in figure 1 is developed. The oxide layer is dissolved and washed away and the contamination level is checked. The contamination detection with this method is one hundred times more accurate than one not using oxide layer. An example is indicated in figure 4 through 7. An oxide film is formed on silicon substrate 12; silicon substrate is cleaned and free from the oxide film. The reagent 16 is mixed with the washed oxide film. The reagent dissolves the oxide film 10, hence, the metallic contamination 14 inside the oxide film 10 is recycled.
