The wafer grinding wheel is one of those semiconductor components that rarely receives attention outside the manufacturing floor, yet it performs a crucial job before a finished wafer becomes individual chips. During back grinding, the wheel removes material from the backside of a semiconductor wafer to achieve the required thickness.

The process becomes increasingly demanding as wafers become thinner and more fragile. DISCO notes that once wafer thickness falls below 100 micrometers, the risk of wafer breakage rises significantly, making wheel selection and wafer handling increasingly important.

DISCO Corporation

From its roots as a grinding-wheel maker founded in 1937 in Kure, Japan, DISCO has grown into the clear leader in semiconductor wafer thinning and dicing. The company now runs four production sites (three in Kure and one in Nagano) and employs several thousand people across the group-recent figures put the total near 7,000 including affiliates. It supplies tens of thousands of diamond grinding and polishing wheels alongside its precision grinders and polishers.

These consumables are used daily in back-grinding silicon, compound-semiconductor and advanced-packaging wafers down to ultra-thin levels. DISCO’s integrated equipment-plus-tool approach and continuous development of porous diamond wheels keep it at the center of high-volume semiconductor manufacturing lines worldwide.

Saint-Gobain

Saint-Gobain’s Norton Winter division develops specialized fixed-abrasive vertical-spindle (FAVS) grinding wheels for semiconductor back-thinning. The company maintains dedicated application labs in Worcester, Massachusetts, and Norderstedt, Germany, where engineers test wheels on actual customer wafers.

Products include coarse and fine wheels capable of grinding 300 mm wafers to 65 µm thickness and specialized tools for GaAs, germanium, SOI and bonded wafers. These wheels are engineered for high stock removal with low force, reducing sub-surface damage and extending usable life on both wire-sawn and laser-sawn material. In today’s fabs the focus is on next-generation porous and free-cutting designs that improve yield on ultra-thin and compound wafers.

TOKYO SEIMITSU (ACCRETECH)

TOKYO SEIMITSU designs and builds high-precision grinders used for wafer thinning and hybrid-bonding processes. In 2025 the company completed a new Nagoya plant with more than 13,000 m² of floor space on a 35,000 m² site, roughly doubling grinder production capacity. The facility focuses on hybrid-bonding grinders and silicon back-grinders while also producing wafer demounting and cleaning machines.

Group sales in the semiconductor equipment segment recently exceeded 120 billion yen, driven by demand for advanced packaging and high-performance computing. The company’s emphasis on high-rigidity machines and integrated metrology continues to support the tight thickness and flatness requirements of modern 3D packaging.
