Edge Grinding Characteristics of Display Glass Substrate
2021年1月8日 Edge grinding is commonly used in the production of display glass panels to round the sharp edges and remove cutting defects of the glass edges. The strength of a display glass panel is actually a measure of the surface defects’ size and number in the glass panel. The larger the defects, the weaker the glass panel will be [ 2 ].
背面研磨(Back Grinding)决定晶圆的厚度 SK hynix Newsroom
2020年10月15日 在由晶圆制成半导体的过程中，晶圆的外观不断发生变化。 首先，在晶圆制造工艺中，晶圆的边缘（Edge）和表面会进行抛光（Polishing），这一过程通常会研磨晶圆的两面。 端工艺结束后，可以开始只研磨晶圆背面的背面研磨工序，能去除在端工艺中受化学污染的部分，并减薄芯片的厚度，这非常适用于制作搭载于IC卡或移动设备的
Kinematics of the grinding process ScienceDirect
2021年1月1日 Kinematics of the grinding process. 1. Main text. The main characteristics of formation of microrelief of work surface of the wheel depend on the law of difference in altitude of cutting edges and corner radiuses of their tops. In general, cutting edges of a wheel are expressed as a random variable. There are different opinions about the law of
Grinding, Edge Grinding, Etching, and Surface Cleaning
2021年1月9日 These processes include wafer grinding and edge grinding (or edge rounding) in wafer forming, etching in wafer polishing, and wafer surface cleaning in wafer preparation. Because silicon material
Semiconductor Wafer Edge Analysis
2005年7月1日 Unpolished edges typically exhibit a surface pattern formed from a grinding process. Surface peaks will touch carrier walls, while valleys will trap particles and impurities. These particles can then propagate to the wafer surface and increase the risk of wafer chipping. Also, deep wells in the edge can be a location site for phosphorus during
Edge Grinding of Si Wafer｜Edge Shaping
