Wafer backgrinding Wikipedia

Wafers thinned down to 75 to 50 μm are common today. Prior to grinding, wafers are commonly laminated with UV-curable back-grinding tape, which ensures against wafer surface damage during back-grinding and prevents wafer surface contamination caused by infiltration of grinding

Thin Silicon Wafers | The Process of Back Grinding for

22/10/2019· Here’s a summary of the back-grinding process to achieve thin silicon wafers: Backside Thinning (or Back Grinding) Wafer grinding or backgrounding is the most popular method for thinning wafers. The dimension to which a wafer can be thinned depends heavily on the machine used, but most thin silicon wafers have around 50 micrometers thickness

Warping of Silicon Wafers Subjected to Back-grinding

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

Semiconductor Back-Grinding

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.

Warping of silicon wafers subjected to back-grinding

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.
