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.

The backgrinding process involves using a diamond-resin bonded grinding wheel to remove the silicon material from the back of a silicon wafer. Using a grinding wheel is highly effective, and faster and less expensive than chemical-mechanical processes and is used to remove the bulk of substrate material prior to final finish grind, polish or

To manufacture the thinnest wafers possible requires a process called back grinding of the wafer, which also poses engineering challenges.

Warping of silicon wafers subjected to back-grinding

Apr 01, 2015 This study investigates warping of silicon wafers in ultra-precision grinding-based back-thinning process. By analyzing the interactions between the wafer and the vacuum chuck, together with the machining stress distributions in damage layer of ground wafer, the study establishes a mathematical model to describe wafer warping during the thinning process using the elasticity theory.

Semiconductor Back-Grinding idc-online

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.

Back Grinding Determines the Thickness of a Wafer SK

Sep 24, 2020 The first step of back grinding is tape lamination. This is a type of coating, which is a process to attach adhesive tape to the front of a wafer. When conducting back grinding, the silicon compound spreads in all directions, and the wafer can be broken or warped by the grinding force.
