Wafer dicing

Dicing of silicon wafers may also be performed by a laser based technique, the so called stealth dicing process. It works as a two stage process in which defect regions are firstly introduced into the wafer by scanning the beam along intended cutting lines and secondly an underlying carrier membrane is expanded to induce fracture.

Grinding of Glass The Mechanics of the Process Journal

From observations of individual grinding scratches and an analysis of the experimental results, it is concluded that virtually all of the grinding energy is expended by viscous deformation. Material removal occurs by flow into chips with silicon carbide abrasive and by brittle fracture preceded by viscous deformation with diamond abrasive.

Wafer backgrinding

Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high density packaging of integrated circuits (IC).. ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 m thick to ensure a minimum of

What is a Silicon Wafer? Silicon Valley Microelectronics

During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish. After polishing, the silicon wafers proceed to a final cleaning stage that uses a long series of clean baths. This process removes surface particles, trace metals, and residues.
