A system and method for projecting an image onto a workpiece are provided. A region of highest plasma density is at the beam axis and workpieces having surfaces to be coated, are radially offset from, and extend along the axis with the surfaces facing the axis and being in the container. Network page generation code for generating the network page is sent to the client computing device in response to the request and in place of the network page. A peripheral portion of the interposer extends laterally beyond the stack of semiconductor dies and is coupled to a plurality of conductive members interposed between the peripheral portion and the package substrate. The temporal averaging and spatial averaging effectively isolates in the difference image coherent changes imbeded in a complex and rapidly changing environment from transient changes inherent to the complex and rapidly changing environment.
