Abstract
Trisilane is used in chemical vapor deposition methods to deposit silicon-containing films over mixed substrates. Such methods are useful in semiconductor manufacturing to provide a variety of advantages, including uniform deposition over heterogeneous surfaces, high deposition rates, and higher manufacturing productivity. An example is in forming the base region of a heterojunction bipolar transistor, including simultaneous deposition over both single crystal semiconductor surfaces and amorphous insulating regions.
