Question & Answer

A 250 mm diameter silicon wafer has a processable area that is circular with a diameter = 225 mm. The IC chips that will be fabricated on the wafer surface are square with 20 mm on a side. However, the processable area on each chip is only 18 mm by 18 mm. The density of circuits within each chip’s processable area is 465 circuits per mm2. (a) How many IC chips can be placed onto the wafer? (b) Using Rent’s Rule with C = 3.8 and m = 0.43, how many input/output terminals (pins) will be needed for each chip package?

In an orthogonal cutting operation, the 0.250 in wide tool has a rake angle of 5°. The lathe is set so the chip thickness before the cut is 0.010 in.

Cost function using regression; scatter plots; three potential cost drivers Laura Mills is the controller of Peer Jets International, a manufacturer of small corporate jets. She has undertaken a project to study the behaviour of overhead cost. She has assembled factory overhead data for the last 30 months from the company’s manufacturing facility. Laura has asked you to develop a model to predict the level of manufacturing overhead.   Required (a)          Create a scatter plot of manufacturing overhead for each of the potential cost drivers. (b)          Would you eliminate any of the potential cost drivers based on the scatter plots? Why? (c)           Explain why you create a scatter plot of the data before you perform regression analysis. (d)          To practice your regression analysis skills, perform a simple regression analysis of manufacturing overhead for each of the three potential cost drivers. Write the cost function from each regression. (e)           Based on the simple regression results, which cost driver does the best job of explaining manufacturing overhead costs? Explain. (f)           Do your regression results support your answer to part (b)? Explain.

Orthogonal cutting is performed on a metal whose mass specific heat = 1.0 J/g-C, density = 2.9 g/cm3 , and thermal diffusivity = 0.8 cm2 /s. The cutting speed is 4.5 m/s, uncut chip thickness is 0.25 mm, and width of cut is 2.2 mm. The cutting force is measured at 1170 N. Using Cook's equation, determine the cutting temperature if the ambient temperature = 22°C.

Relevant information; uncertainties; information for decision-making Janet Baker is deciding where to live during her second year of university. During her first year, she lived in the university residence college. Recently her friend Rachel asked her to share an off-campus flat for the upcoming school year. Janet likes the idea of living in a flat, but she is concerned about how much it will cost.   To help her decide what to do, Janet collected information about costs. She would pay $400 per month in rent. The minimum lease term on the apartment is six months. Janet estimates that her share of the utility bills will be $75 per month. She also estimates that groceries will cost $200 per month. Janet spent $350 on a new couch over the summer. If she lives in the university residence college, she will put the couch in storage at a cost of $35 per month. Janet expects to spend $7500 on university fees and $450 on books each semester. Room and board on campus would cost Janet $2,900 per semester (four months). This amount includes a food plan of 20 meals per week. This cost is non-refundable if the meals are not eaten.   Required (a)     Use only the cost information collected by Janet for the following tasks. (i)    List all of the costs for each option. Note: Some costs may be listed under both options. (ii)   Review your lists and cross out the costs that are irrelevant to Janet’s decision. Explain why these costs are irrelevant. (iii)  Calculate and compare the total relevant costs of each option. (iv)  Given the cost comparison, which living arrangement is the better choice for Janet? Explain. (b)     Identify uncertainties in the cost information collected by Janet. (i)    Determine whether each cost is likely to be (1) known for sure, (2) estimated with little uncertainty, or (3) estimated with moderate or high uncertainty. (ii)   For each cost that is known for sure, explain where Janet would obtain the information. (iii)  For each cost that must be estimated, explain why the cost cannot be known. (c)     List additional information that might be relevant to Janet’s decision (list as many items as you can). (i)    Costs not identified by Janet (ii)   Factors other than costs (d)     Explain why conducting a cost comparison is useful to Janet, even if factors other than costs are important to her decision. (e)     Consider your own preferences for this problem. Do you expect Janet’s preferences to be the same as yours? How can you control for your biases as you give Janet advice? (f)      Think about what Janet’s priorities might be for choosing a housing arrangement. How might different priorities lead to different choices? (g)     Describe how information that Janet gains over this next year might affect her future housing arrangements. Suppose Janet asks for your advice. (h)     Use the information you learned from the preceding analyses to write a memo to Janet with your recommendation and a discussion of its risks. Refer in your memo to the information that would be useful to Janet.
