  • TWO-PIECE MAGNETICALLY COUPLED SUBSTRATE ROLLER USED IN MEGASONIC CLEANING PROCESS
    Publication number: 20090159100
    Abstract: Mechanisms which rotate semiconductor substrates while immersed in wet chemicals are often complex due to a need to prevent leakage of the chemicals. Wear of the mechanisms necessitates replacement, entailing significant maintenance costs. A two-part semiconductor substrate roller is disclosed which consists of a rotary power coupler and an inexpensive replaceable roller component which attaches to the rotary power coupler in a simple manner. An external rotary power source turns the rotary power coupler through a mechanism that prevents leakage of the wet chemicals from the processing equipment. The replaceable roller component may be attached to the rotary power coupler by any of several mechanisms. The cost of the replaceable roller component is less than 10 percent of the cost of the rotary power coupler. A method of replacing the replaceable roller component and a method of processing semiconductor substrates using the instant invention are also disclosed.
