ULTRA-LOW PARTICLE SEMICONDUCTOR CLEANER |
摘要 |
<p>A method for cleaning a semiconductor wafer. The method includes immersing a wafer in a liquid having water. The wafer has a front face, a back face, and an edge. The method also includes providing a substantially particle free environment adjacent to the front face and the back face as the liquid is being removed. A step of introducing a carrier gas having a cleaning enhancement substance during the providing step also is included. The cleaning enhancement substance dopes the liquid which is attached to the front face and the back face to cause a concentration gradient of the cleaning enhancement substance in the attached liquid to accelerate fluid flow of the attached liquid off of the wafer.</p> |
