Problem
1. The silicon atom density is 5 × 1022 cm-3. If dopant concentration is 10×15 cm-3 of boron, how far are the boron atoms from each other?
2. IC chips are getting larger even though the linewidths are scaled down because more functions are integrated on a chip. Calculate the signal path resistance for
(a) 3µm wide, 1µm thick aluminium conductors, 500µm long (resistivity 3µohm-cm)
(b) 0.3 µm wide, 0.5µm thick, 1 mm long copper conductors (2 µohm-cm)
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
