A tip of a human hair is typically larger than a transistor. Transistors, being microscopic devices used in electronic circuits, are much smaller in size compared to the diameter of a human hair.
Vacuum tubes initially led to an increase in size of electronic devices due to their bulky nature and need for additional components. However, as technology advanced, the development of smaller, more efficient components such as transistors and integrated circuits led to a decrease in size of electronic devices.
A transistor is typically smaller than the tip of a human hair. Transistors are microelectronic devices used in electronic circuits and are designed to be very small, often in the nanometer range. The tip of a human hair is usually larger in comparison.
Transistors are made that are smaller than a human hair. Used as part of an integrated circuit chip, which may contain thousands of transistors.
PMOS transistors are typically larger than NMOS transistors in CMOS design because the mobility of holes (the charge carriers in PMOS) is lower than that of electrons (the charge carriers in NMOS). This means that a larger current-carrying area is needed in the PMOS to achieve the same performance as the NMOS transistor. By making the PMOS larger, designers can balance the drive strengths of the two types of transistors in a CMOS circuit.
Integrated cicuits, or IC's are manufactered for many different purposes such as as amplifiers, switches, or for tuning in specific radio or TV channels. An integrated circuit is a miniature electronic device containing many interconnected circuit elements formed on a tiny silicon semiconductor chip. Before integrated circuits were invented, individual electrical components were connected by soldering together the wires attached to them. These components were hundreds of times larger than the electronic elements formed on an IC, and older electronic devices used to be considerably larger and less reliable than they are now.
The first computers used valves and took up a lot of space. The development of transistors enable modern computers that could sit on a desk. Miniaturisation of components has led to the small, powerful, hand-held electronic devices we use today.
This depends on the IC, and package size. If you look in the data sheet for the particular IC you are wanting information about, there will be a page dedicated to the physical size and layout of the chip.
Integrated is creating, applying or mixing two methods together to build a larger base. For example, two marketing campaigns can be used to maximize sales.
That depends on the transistor, but in modern integrated circuits, a single transistor is somewhere around a hundred atoms thick; the largest atom is about 0.5 nm in diameter, so a hundred atoms would be about 50 nm. On the other hand, a typical human hair, according to Wikipedia, has a width "from 0.017 to 0.18 millimeters"; that would be 17-180 µm, which is much larger.
Vacuum tubes
If you're talking integrated circuits, generally it's a heat sink and/or a fan, if needed. For larger devices, the same rules may apply, but there are several types of additional cooling, such as water circulation, refrigerants, etc. or different combinations. It really all depends oh how much heat you have to dissipate.
