please show the working and write properly for each word, and
explain the working
Given an 8-inch wafer costing $2200 each, with Y= 80%, Ypa = 98% and die area of (4 x 4) mm², estimate the cost per die. The die may be shrunk to (3.3 x 3.3) mm² in a more advanced process that costs $3000 per wafer. Justify if it is worth moving to the new process if the volume is large enough.
