An engineer at a microcircuit factory will inspect a batch of silicon wafers to try to find defects. Assume that there are four defective integrated circuits in a container containing twenty wafers. For that inspection two random wafers are selected. Calculate the probability that:
a) None of them have defects
b) At least one of the two has no defects.

One integrated circuit design calls for the diffusion of arsenic into silicon wafers; the background concentration of As in Si is 2.5 × 1020 atoms/m3. The predeposition heat treatment is to be conducted at 1000°C for 45 minutes, with a constant surface concentration of 8 × 1026 As atoms/m3. At a drive-in temperature of 1100°C, determine the diffusion time required for a junction depth of 1.2 μm. For this system, values of Qd and D0 are 4.10 eV and 2.29...

A new process has been developed for applying photoresist to 125-mm silicon wafers used in manufacturing integrated circuits. Ten wafers were tested, and the following photoresist thickness measurements (in angstroms x1000) were observed: 13.3987, 13.3957, 13.3902, 13.4015, 13.4001, 13.3918, 13.3965, 13.3925, 13.3946, and 13.4002. (a) Test the hypothesis that mean thickness is 13.4 x 1000Å. Use = 0.05 and assume a two sided alternative. (b) Find a 99% two-sided confidence interval on mean photoresist thickness. Assume that thickness is normally...

An engineer is responsible for monitoring the quality of a batch of 1000 ohm resistors. To do so, the engineer must accurately measure the resistance of a number of resistors within the batch, selected at random. The results obtained are shown below for samples 1 to 30. 1006, 1006, 978, 965, 988, 973, 1011, 1007, 935, 1045, 1001, 974, 987, 966, 1013, 960, 976, 954, 1004, 975, 1014, 955, 973, 993, 1023, 992, 981, 991, 1013 and 998.

An engineer in charge of the design of a plant must choose either a batch or a continuous system. The batch system offers a lower initial outlay but, owing to high labor requirements, exhibits a higher operating cost. The cash flows relevant to this problem have been estimated as follows: year 0 year 1-10 (after tax) discounted cash flow rate of return net present worth at 12% batch system -$20,000 $5,600/year 23% $14,000 continuous system -$30,000 $7,650/year 20% $17,600 Check...

cost value pricing Must show work CVP Question Catalonia Company (CC) makes silicon wafers that its salespeople sell B-to-B for $100/wafer. All salespeople get a commission equal to 10% of the revenue from the wafers they sell, and in addition, the salespeople receive a base salary of $40,000 per person. In 2017, CC had 10 sales people, and its total sales revenue was $10,000,000. The manufacturing facility used to make the wafers has a fixed cost of $2,000,000, and a...
