Can we make transistor at home?
It is just not possible to fabricate a transistor at home.
How do you create a transistor?
Easy n-Channel Transistor
- Start with p-doped silicon.
- Grow thin silicon dioxide layer.
- Deposit nitride layer.
- Apply photoresist polymer.
- Bring in mask.
- Turn off regular light.
- Expose to UV light.
- Turn on regular light.
What can we use instead of transistor?
The most obvious alternatives to transistors are vacuum tubes and electromechanical relays. In addition, magnetic amplifiers (magamps) are useful. Piezoelectric relays are rare. Rotating amplifiers, such as amplidyne motor-generator machines are useful at higher power levels.
What is used to make transistors?
Most transistors are made from very pure silicon, and some from germanium, but certain other semiconductor materials are sometimes used. A transistor may have only one kind of charge carrier, in a field-effect transistor, or may have two kinds of charge carriers in bipolar junction transistor devices.
How do I choose a good transistor?
In choosing a suitable switching transistor:
- The transistor’s maximum collector current must be greater than the load current.
- The transistor’s maximum current gain must be at least 5 times the load current divided by the maximum output current from the IC.
How interchangeable are transistors?
Others are set up for a particular application even though they are all part of the same family of components (capacitors, resistors, inductors, transistors, diodes). So yes transistors are interchangeable, if the type (npn/pnp) and required specs match.

How was the first transistor made?
The first high-frequency transistor was the surface-barrier germanium transistor developed by Philco in 1953, capable of operating up to 60 MHz . These were made by etching depressions into an N-type germanium base from both sides with jets of Indium (III) sulfate until it was a few ten-thousandths of an inch thick.
How big are modern transistors?
Modern silicon commercial transistors may be smaller than 45 nanometers in size. They’re so small that NVDIA ‘s new graphics card (codenamed GF100 ) has more than 3 billion transistors, the most ever jammed into one chip.
What is the history of transistor?
History of the transistor. A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. The vacuum-tube triode, also called a (thermionic) valve, was the transistor’s precursor, introduced in 1907.
