Epitaxial growth is used in integrated circuit—

1. Because it produces low parasitic capacitance
2. Because it yields back-to-back isolating junctions
3. To grow single crystal n-doped silicon on a single crystal p-type substrate
4. To grow selectively single-crystal p-doped silicon of one resistivity on p-type substrate of a different resistivity
