backgrinding machine method

HANA Micron Technology

Using a grinding wheel, backgrinding is one of packaging steps to make wafer thinner for stacking. Currently, wafers are thinned 75μm thickness below for multi-stacking. Hana Micron has two kinds of machines wet and dry polishing. Prior to grinding, wafers are laminated with UV backgrinding tape to prevent surface damage on the top of a wafer.

ADAPTIVE PATTERNING FOR PANELIZED PACKAGING

A common method for undergo backgrinding, laser marking, and singulation, just like WLCSPs. The resulting package is often just slightly placed using a high-speed die placement machine and rigidly attached to a package substrate, typically a strip containing an array of units. Subsequently, a wire bonder

Etching (microfabrication) Wikipedia

The etch chemistry is dispensed on the top side when in the machine and the bottom side is not affected. This etch method is particularly effective just before "backend" processing, where wafers are normally very much thinner after wafer backgrinding, and very sensitive to thermal or mechanical stress.

Spectroscopic Measurements of Silicon Scientific.Net

The optical microgauge system by means of near-infrared spectroscopic measurements was proposed as the thickness monitoring tool in the silicon wafer thinning process. The Fabry-Pelot interferometry and Beer's law were employed as the principles of the system for extracting the wafer thickness from optical spectroscopic system prototyped in this study.
