Read OnStudies the strength distribution of semiconductor chips on a wafer, and the influence of the back-side grinding process on the chip strength.. The three-point bending test, complying with the ASTM standard E855, was adopted to measure the chip strength. The first set of test vehicles is from three 8-inch wafers. One is of 28 mils thick without backside grinding, and the …
Read OnSince this process also uses the brittle mode, micro-cracks called chippings are generated on the front and rear sides of the wafer. As a countermeasure for this problem, dicing before grinding (DBG) process is also applied. In this process, as shown in Fig. 2, grooving (half-cut dicing) is performed from the front side before grinding.
Read OnThe grinding process is one of the most important and widely used machining processes to achieve the desired surface quality and dimensional accuracy.

Read OnGrinding is a staple size-reduction process to produce food powders in which the powdered form is chemically and microbiologically stable and convenient to use as end products or intermediate products. The moisture content of food materials before grinding is a particularly important factor, since it determines the materials' physical properties and the powder …
Read OnTree stump grinding is the process of sanding down the stump of a tree until it no longer protrudes from the ground. This leaves a sawdust-like residue in its place but does not remove the root of the tree belowground. Its purpose is to eliminate the visual part of the stump rather than digging up the roots of the tree altogether.
