A Dicing Saw is used to cut(or dice) or groove semiconductor wafer into small square, or die. Grinder The grinder is used to grind a wafer piece into desired thickness.
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.
What is a Silicon Wafer? Silicon is a gray, brittle, tetravalent, chemical element. It makes up 27.8% of the earth’s crust and next to oxygen, it is the most abundant element in nature. Some of the most common materials that contain silicon are quartz, agate, flint, and common beach sand, among others.
