A semiconductor diode has these advantages over a vacuum tube:
- smaller
- cheaper
- runs cooler
- much more rugged
- very long life
- no heater, so needs no power supply to work
- less electrically noisy
- can be made part of an I.C.

When were the vacuum tubes invented?
1904, a diode by Fleming.
Is the diode and semiconductor diodes are the same?
Today, all diodes are semiconductor diodes. However, the first diodes were piles of washers of different metals that together made a diode, and specially constructed vacuum tubes. There may still be markets for other types of diodes in very high voltage circuits, but you or i are unlikely to come in contact with them.
How semiconductors are used in electronic devices?
what is semiconductor state advantages of semiconductor devices over electronic tubes
What is alternative of semiconductor?
as a material, nothingas a device to perform the function, vacuum tubes or magnetic amplifiers
What is diode volve?
I think you mean 'diode valve'! A 'valve' is the British term for what Americans call 'tubes' or, more accurately, 'vacuum tubes'. So, a 'diode valve' is a thermionic valve generally used as a rectifier, much in the same way that a semiconducting diode is used, these days.

Which is better a vacuum tube or a micro chip?
It depends on the application. Vacuum tubes work better under certain operating conditions and frequencies. The problem with vacuum tubes is they are not as easy to mass produce as semiconductor devices, and semiconductor devices such as integrated circuits can have litterally thousands or millions of transistors and other components on a single chip. Such scaling is not possible with vacuum tubes, though there is some research in the MEMS (Micro Electro Mechanical) field to suggest that micro scale vacuum tubes could be mass produced within an integrated circuit. Such applications could be useful in the Terahertz frequencies. When a lowcost and compact solution is preferred generally the silicon based microchips will be the best option.
How many vacuum tubes are in the Univac I computer?
It used 5200 vacuum tubes.
Do they still make vacuum tubes?
Do they still make vacuum tubes? Yes! Vacuum tubes are still used in applications where high power is required. And that's because there are no solid state (semiconductor) devices that can deliver what a hefty vacuum tube can produce. We see vacuum tubes used in the broadcast transmitters that radio and TV stations send out their signals with. We also see vacuum tubes used in radar applications, and in things like X-ray generation. You want big power? Get a vacuum tube to deliver it. As we move up the power scale, we'll see solid state devices falling off the truck until we're left with just vacuum tubes. There's a bit more.Now that newer technology has appeared and is becoming more common, the cathode ray tube (CRT) in "regular" television sets is disappearing. (The CRT is a vacuum tube.) There are still plenty of these "older" units being used and marketed in other parts of the world. But the chances are excellent that you encounter a device using a vacuum tube at least daily. The tube we're talking about is called a magnetron, and it is the vacuum tube (a diode with associated magnets that works as a cavity resonator) which generates the microwaves energy that is used in microwave ovens.Vacuum tubes were developed and advanced long before solid state devices came into being. But, though semiconductor technology is at the heart of almost all electronic equipment around us today, the vacuum tube still does the jobs that solid state devices cannot manage. And this will continue to be the case for some time to come.
What are the benefits of vacuum tubes?
vacuum tubes help us today with many things. the most important 1 is techology. If we didn't have vacuum tubes we wouldn't have computers. just thik of a life with out computers or t.v. vacuum tubes are also used in radios. so if vacuum tubes hadn't been invented we would not be able to use all the techology we use today.=]
