Deposition (CVD and PVD)
What is generally done to increase the deposition rate in sputtering?
- AIncrease the power applied to the target
- BMake the gas pressure extremely high
- CReduce the power to the target to zero
Show answer and explanation
Answer: A. Increase the power applied to the target
Increasing the power applied to the target increases the number and energy of ions striking it, ejecting more atoms and raising the deposition rate. However, attention must be paid to target heating and cracking and to effects on film quality.
