Fine grinding of silicon wafers ScienceDirect

Grinder: Strasbaugh surface grinder model 7AF; wheel: #2000 mesh resin bond diamond wheel, 280 mm diameter; test wafers: 125 mm silicon wafers; removal amount: R. Van De Merwe, Subsurface damage for Si wafers, Saint-Gobain Industrial Ceramics — Internal Report, Structural Analysis Group, Northboro R&D, May 1998. In SSG, as shown in Fig. 3, a silicon wafer is held on a porous ceramic chuck by means of vacuum.The grinding wheel is a diamond cup wheel. The grinding wheel and the wafer rotate about their own rotation axes simultaneously, and the wheel is fed towards the wafer along its axis [9], [12], [13].After the wafer front side is ground, the Simultaneous double side grinding of silicon wafers: a

Development of rotary table grinding machine for large diameter Si

Si wafer diameter tends to be increased from 300 mm to 450 mm in order to increase semiconductor device productivity. To this end, the authors developed a rotary grinding machine with high stiffness, equipped with water hydrostatic bearings. This grinding spindle is designed to govern infeed motion of the grinding wheel. This study investigates the A high stiff rotary grinding machine for 450mm Si wafer has been developed. In order to improve static stiffness of the spindle unit, components for rotary and axial motion were built in the spindle.Development of rotary table grinding machine for large diameter Si

Effects of grinding parameters on surface quality in silicon nitride

The Si 3 N 4 grinding experiment was performed on a CNC high precision surface grinding machine MGK7120×6/F, using a water-based grinding fluid and a resin-bonded diamond grinding wheel with a size of ϕ200 mm×ϕ32 mm×15 mm. Fig. 1 shows the grinding experimental system. The grinding force was measured using a piezoelectric A grinding machine is a production machine tool used in the manufacturing industry in which the grinding wheel is attached in the tool post and the workpiece is fixed to the work table and when the operation starts it removes the unwanted material to get the desired surface finish, correct size, and accurate shape of the workpiece.Grinding Machine: Definition, Parts, Working Principle, Operation

Rounded silicon edges on the surface of Al-Si alloy cylinder

A cast hyper-eutectic aluminum-silicon alloy cylinder liner had been honing to an inner diameter of 110 mm.The tensile strength was 298 MPa, the yield strength was 251 MPa, and the hardness was 135 HBS.The main chemical compositions of it were summarized in Table 1.The specimens were cut from Al-Si alloy cylinder liner with Definition. A grinding machine is a machine for material removal with geometrically non-defined, bonded cutting edges, where the relative movement between tool and workpiece is rotational or linear. The machine further must provide relative feed and positioning movements between tool and workpiece. The movements between tool Grinding Machines SpringerLink
