transistor size depends on its channel length, that is the length of the region in which a transistor act as an electron tube. the shorter the region, the lowest the resistance, the fastest the transistor, etc... so, it is always good to scale transistor size. problem is that you have to apply a 'good' electrical field in the channel, in order to drive a good 'ON' or 'OFF' state for your transistor. that's why it's not easy to scale their size.
before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
A: The transistor has not changed practically the same size what has changed is the packaging and the technology of mapping substrates
A silicon transistor is a transistor made of silicon.
Similar to a 2N3906 PNP transistor

It reduced the size of electronic appliances
Integrated circuit processes are characterized by the feature size, which is the minimum size of a transistor or a wire in either the x or y dimension. Feature sizes have decreased from 10 microns in 1971 to 0.09 microns in 2006; in fact, we have switched units, so production in 2006 is now referred to as "90 nanometers," and 65 nanometer chips are underway. Since the transistor count per quare millimeter of silicon is determined by the surface area of a transistor, the density of transistors increases quadratically with a linear decrease in feature size.
A silicon transistor is a transistor made of silicon.
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
A Unijunction Transistor is a transistor that acts solely as a switch.

how does a transistor behaviour
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
