Apparatus and method for in-situ measuring of vibrational energy in a process bath of a vibrational cleaning system |
摘要 |
Apparatus and method are provided for in-situ measurement of vibrational energy applied to a wafer in a process bath of a vibrational cleaning system. The apparatus may be made up of a test wafer comprising an array of pressure sensing elements disposed thereon for monitoring power level variation of a time-varying pressure wave. The time-varying pressure wave is indicative of vibrational energy that would be applied to a wafer in the process bath in the position of the test wafer.
