AI Thread Summary
Diodes are primarily made through the creation of p-type and n-type junctions, which can be achieved using diffusion methods in semiconductor fabrication. The CMOS (complementary metal oxide semiconductor) process is a key technique that outlines how diodes are constructed, as it involves diffusing wells to form these junctions. For more advanced diodes, ion implantation is utilized to customize doping profiles, enhancing their performance characteristics. Numerous resources are available online that detail these fabrication methods. Understanding these processes is essential for anyone interested in diode manufacturing.

please I want to know how diodes are made practically
I searched for this in many seatch engines but I don't found any resukts that satisfies me
I hope u could help
thanks in advance

Look up any of the 7 million websites that describes CMOS (that is complementary metal oxide semiconductor) fabrication and it will show you how diodes are made. Every time you have a p-type/n-type junction you have a diode and cheap diodes are often made using diffusion. When they describe how the wells are diffused in the CMOS process they are describing diode fabrication.

Advanced diodes also make use of ion implantation to tailor their doping profiles (and therefore their responses).

allright...I will search for this

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
