The wafers are ground on the backside of the semiconductor circuit pattern, hence the name "back grinding" (BG) for this process. When processing down to a thickness of several hundred microns, more than 100 μm thick, the risk of wafer breakage is not so high.
R631DF. Application Example (s): Wafers. Industry: Information Technology/Semiconductor. Grinding Capacity/Lapping capacity: Ø200mm. Description: Special grinder for hard but brittle wafers. High-precision grinder to replace lapping machines. Fully automated cassette to cassette operation. Grinding parameters of each wafer can be stored.
For wafers with diameters of 200 mm, it is typical to start with a wafer thickness of roughly 720 µm and grind it to a thickness of 150 µm or less. The coarse grinding typically removes approximately 90 percent of the excess material. A typical two-step backgrinding operation will use dual spindles with grinding wheels mounted on each spindle.
Semiconductor Back-Grinding The silicon wafer on which the active elements are created is a thin circular disc, typically 150mm or 200mm in diameter. During diffusion and similar processes, the wafer may become bowed, but wafers for assembly are normally stress relieved and can be regarded as flat.
Wafer Edge Grinding Machine Guide The Specialized Wafer Edge Grinding Machine. Semiconductor wafer grinders Many companies have developed several types of grinding machines used in the semiconductor industry for the production of silicon wafers and the production of integrated circuits.
Semiconductor wafers are made of silicon, which is the second most abundant element on Earth (after oxygen) and the seventh most abundant element in the entire universe. 2. Since the sand used to make semiconductor wafers must be very clean, most of the sand used for these processes is shipped from Australian beaches.

A typical semiconductor wafer may have a starting thickness of 775 µm, but the amount of material removed varies by device type. For example, the thickest wafers are used for logic gates and are 100 µm thick. DRAM memory usually requires semiconductor wafers with a thickness of 50 µm instead. MEMS memory is typically around 30 µm thick.
