A system and method for cleaning probe pins on a probe card used in testing a semiconductor device during fabrication thereof. The glossy pink center zone extends along the rays through the body to roughly 1 inch of the petal edge. The light-pervious member is a transparent structure; and the colloid member forms a transparent structure with a thick center and a thin periphery using the surface tension of colloid material. , and electrochemically treating the patterns to allow the conductor to deposit in a desired cross-sectional area in the inside. Screening methods for identifying similar ALH-immunosuppression compounds are also described.
