Wafer Backgrinding | Silicon Wafer Thinning | Wafer Backgrind

Wafer backgrinding starts with a large grit wheel to remove most of the surface, and wheels with a finer grit are used to finish polishing the silicon wafer to the desired thickness. To prevent contamination, deionized water is used to wash debris from the surface throughout the wafer thinning process.

Wafer backgrinding - Wikipedia

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 μm thick to ensure a minimum of mechanical stability and to avoid warping during high-temperature processing steps.

Wafer Backgrind - www.EESemi.com

Wafer Backgrind Wafer Backgrind is the process of grinding the backside of the wafer to the correct wafer thickness prior to assembly. It is also referred to as 'wafer thinning.' Wafer backgrinding has not always been necessary, but the drive to make packages thinner and thinner has made it indispensable.

Backgrinding - Desert Silicon

Backgrinding is the process of removal of silicon from the back of wafers following conventional semiconductor processing. The process is primarily utilized in thinning wafers for commercial semiconductor wafer fabs. Wafers are first laminated using an automatic taping machine. After inspection, they are placed on a Disco 84X series infeed grinder.

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. Frequently there will be a departure from roundness, with a flat or notch
