Therefore, a modern wafer grinding machine begins with a coarse grinding wheel to get a fast removal of the silicon and at the end follows a fine grinding process step with small grit size grinding wheel. This final process is absolute necessary when thinning down to 50 μm in order to minimize subsurface damage and stress.
Edge grinding, also known as Edge Profiling, is a process that is common to the manufacture of nearly all semiconductor related wafers and wafers that are used in the manufacture of many other electronic, solar, and nanotechnology devices. The edge grinding step is critical to the safety of the wafer edge.
Back grinding is a process that removes silicon from the back surface of a wafer. Silicon Valley Microelectronics provides grinding on our own substrates or on customer supplied wafers. We process bare and device patterned wafers with high yield and offer wafer thinning to customer specifications. SVM Wafer Back Grinding Capabilities:
