发明名称 METHOD AND APPARATUS FOR SPUTTER CLEANING LEAD FRAMES
摘要 <p>Methods and apparatus (104) for generating uniform ion bombardment and plasma cleaning over the entire surface of an object or collection (116) of closely spaced objects having a high aspect ratio by use of a low pressure plasma. The parameters of plasma density, pressure, biasing, and spacing are manipulated to optimize ion current deep in the gaps between the objects and minimize processing time.</p>
