- Answer each of the following questions in one to three sentences. (a) What is lithography field? (b) What is misalignment in lithography? (e) What is selectivity in an etching process? (d) What is end-point detection in an etching process?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.basically we’re designing a machine that has rollers to flattened and rotating shaft to roll a strip of dried leaves into a bundle. Now we were advised to provide calculations with the relevant engineering parameters including the sizing of gears, belt and pulley, the torque requirement of each machine element and the power rating of the motor. The entire machine is powered by a stepper motor connected with a timing belt and pulley for power transmission. and gears that will rotate the shaft. Can you give us the flow of calculations from the rollers, the rotating shaft, up to sizing pf belt and pulley and gear ratios, with the last step as finding the power requirement (in hp) of the entire machine?
- How can acoustic-assisted 3D printing revolutionize the production of microscale mechanical components and devices?Two students decided to print a prototype for a gear. Student A use layer thickness of .1 mm and an infill density of 25%. Student B use a layer thickness of 0.07 mm and an infill density of 45%. Which student will take less time to print the gear? Select one: Stu nt since the ckness of layer is smaller and the infill density is higher. O We can't decide which process takes less time O Student A since the thickness of the layer is larger and the infill density is lower. Student B because thickness is higher than B and the infill density has no effect on the process speed. Student A because thickness is higher than B and the infill density has no effect on the process speed.Create an open ended question about processing nanomaterials with answer
