Silicon Wafer

5.1.4 Edge Grinding. Silicon wafers after cutting have sharp edges, and they chip easily. Wafer edge is shaped to remove sharp, brittle edges; rounded edge minimizes risk for slipping, too. Edge shaping operation makes the wafer perfectly round (off-cut wafers are oval shaped after slicing), the diameter is adjusted, and orientation flat (s) or ...

A wafer-scale method to obtain epitaxial germanium (Ge) on crystalline silicon (Si) using liquid-phase-crystallization (LPC) is presented. The technique provides …

Silicon Wafer

An interesting variation of the standard silicon wafer is the SOI substrate. To produce these wafers, two silicon wafers are bonded together, using silicon dioxide of approximately 1–2 μm thickness as a bond layer. One of the silicon wafers is thinned down to a thickness of 10–50 μm. The exact layer thickness will depend on the application.

The influence of backgrinding on the fracture strength of 100 mm …

The influence of grinding geometry and damage depth on the fracture strength of 100 mm diameter (1 1 1) p-type silicon wafers has been studied. The fracture strengths were measured in a biaxial flexure test after the wafers were ground to 0.36 mm from 0.53 mm thick, in a grinding apparatus that produces a swath of swirls on the silicon wafer …

Elimination of blind zone in nanoparticle removal on silicon wafers

The blue curve, calculated based on Ye's model, shows that M c /M r > 1 as S ranges from 1.4 mm to 2.8 mm, suggesting that the PSL particles located in the blind area with a radius of 1.4 mm cannot be removed; and the largest region the shockwave could effectively clean should have a radius smaller than 2.8 mm.

1. Introduction. The conventional way of pulling mono-crystalline Czochralski (CZ) silicon ingots for electronic applications usually results in wafers, which contain voids in concentrations between 10 6 and 10 7 cm −3. These ingots are pulled rapidly in the vacancy-rich regime. During cooling the vacancies supersaturate and agglomerate.
