A siilicon boule has been processed through grinding to provide a cylinder whose diameter = 281 mm and whose length = 899 mm. Next, it will be sliced into wafers 0.8 mm thick using a cut-off saw with a kerf = 0.5 mm. The wafer thus produced will be used to fabricate as many IC chips as possible for the personal computer market. Each IC has a market value to the company of $108. Each chip is square with 17 mm on a side. The processable area of each wafer is defined by a diameter = 265 mm. Estimate the value of all of the IC chips that could be produced (in $), asssuming an overall yield of 84% good product.
what is gross error? how to eliminate it gross errors?
Use diagrams and images to describe the following processes of degradation and give examples of where the type of degradation will occur:
1) Stress corrosion cracking

- Five engineers measure the thickness of a slab using a meter stick and a vernier caliper. One engineer got a thickness of 4.3 cm ± 0.1 cm using a meter stick, the other four engineers measured a thickness of (a) 4.32 cm ± 0.01 cm, (b) 4.31 cm ± 0.01 cm, (c) 4.24 cm ± 0.01 cm, and (d) 4.43 cm ± 0.01 cm respectively using the caliper.
