Unformatted text preview: a patterned metal line on the silicon wafer without doing any etching of the metal itself. 4) a) Describe the pros and cons of various metals used in interconnects. b) What is electromigration and what are some of the consequences of electromigration in electronic devices. 5) The time to turn on a MOSFET is directly proportional to the product of the gate resistance and the capacitance of the gate. The gate resistance is proportional to the area of the gate times the thickness of the metal used for the gate. The capacitance of the gate is proportional to the area of the gate divided by the thickness of the gate oxide. If the length and width of the gate, the thickness of the gate metallization, and the thickness of the gate oxide are all multiplied by the same factor n, where n< 1, then how does the time to turn on the MOSFET scale? (Use mathematical equations for your answer)....
