1.	Which gas is used to fill the chamber in the grown junction type transistor construction?(a) helium(b) boron(c) nitrogen(d) oxygenI have been asked this question in my homework.I need to ask this question from Transistor Construction in section Transistor Characteristics of Electronic Devices & Circuits
Answer» RIGHT choice is (c) nitrogen For explanation I would say: In the process of TRANSISTOR CONSTRUCTION, a crucible is placed in the chamber. This chamber consists of hydrogen or nitrogen. These gases HELP in the prevention of oxidation. It also contains purified GE or Si at a temperature few degrees above its melting point.
