Annealing is a critical process in semiconductor manufacturing where silicon wafers get rapidly heated to get temperatures using powerful infrared heaters. Annealing helps to reduce defects in materials after implantation or deposition processes. a) You have been asked to design a temperature sensor an annealer with a range of up to 1500°C.Select a suitable thermocouple from the table below and give an explanation for your choice. 80 E 70 60 K 50 40 -C 30 20 10 0. 500 1000 1500 2000 2500 Temperature ("C) b) To record the temperature, you use a microcontroller with an ADC. The ADC is referenced to a 2.048V reference voltage source. To make use of the entire range of the ADC, what gain does the amplifier require for your chosen Thermocouple? c) You want to read the temperature with a resolution of 0.5°C. What is the minimum number of bits that your ADC requires? d) The thermocouple has a time constant, t, of 300ms. If the annealer heats from room temperature (20°C) to 820°C. What…
