US6077149A - Method and apparatus for surface-grinding

It will be enough if this surface-grinding is conducted by means of, for example, the surface-grinding means of the surface-grinding machine 20, that is, the grinding stone 22. A wafer HW1, the upper surface of which has been surface-ground, is released from the vacuum chuck means 12 together with the base plate 14 (Step (d), FIG. 1(c))

Precision Grinding of Ultra-Thin Quartz Wafers

Precision Grinding of Ultra-Thin Quartz Wafers

Wafer Grinding Once the vacuum chuck has been machined under controlled grinding conditions, the wafer can be mounted and ground. Since the wafer is very thin, its back surface conforms closely to the chuck surface. The front surface is then ground as flat as possible, again using real-time feed-back control and a ref-erence flat. •

Model 72/865 (multi). This machine combines the functionality of the previous two models 72/860 and 72/852. Smaller factories may benefit from a machine that combines surface grinding and chamfering. However, larger factories separate surface and chamfer grinding because the latter process takes only about half the time of the former

Modeling of Vibration Condition in Flat Surface Grinding

This article presents a new model of the flat surface grinding process vibration conditions. The study establishes a particular analysis and comparison between the influence of the normal and tangential components of grinding forces on the vibration conditions of the process. The bifurcation diagrams are used to examine the process vibration conditions for the depth of cut and the cutting

Fast and precise surface measurement of back-grinding

The roughness of the surface should be often in the range of Ra 10 nm or even 1 nm which is a challenge for mechanical grinding machines. Is the roughness too high or not uniformly distributed on the wafer surface, the later process steps as wire bonding, flip chip assembling, molding and testing can damage the thin chip through breakage
