I've been told both that it causes ions to penetrate too deep due to the existence of "channels" in the crystal structure that offer very little resistance to the penetrating ion.
I've also been told that it is a process of ions losing energy as they travel through the substrate which causes them to not go deep enough.
so which is it? any good sources would be appreciated
Can anyone suggest me some online certification course so that I can get into Semiconductor fabrication industry?
Currently I’m working in an organic/inorganic coating industry (automotive). I’m trying to get a certification/some basic idea in below mentioned topics as this will increase weightage of my resume.
- Deposition.
- Lithography.
- Polishing.
- Plasma chamber-Working.
- Electro chemical processing.
- Plasma deposition (cvd, Pvd), dry etching, ald deposition etc.
Please let me know, thank you.
In India, there are only 2 semiconductor laboratories owned by ISRO and DRDO each and yet to have a full fledged commercial plant. This means, all the electronics goods which are manufactured here in India have to get all their chips to be imported from outside. Electronic items have become the basic necessities in this modern world. Almost every other device has some kind of circuitry, now a days. In India, the consumer size for electronic goods is also huge. If we can’t make a single electronic device, without importing any of its part then how can we be AATMANIRBHAR ?
I'm a researcher working on characterising MOSFETs and IGBTs and, for now, I can only measure a single MOSFET or IGBT using a keithley sourcemeter. This got me thinking, how do big companies do it?
For example, when Onsemi release a new MOSFET they usually measure a batch of devices and average out the results to show the graphs for "Typical Characteristics" in their datasheets, so how do they do it?
I'm imaging they will have some sort of automated system to measure 100 or a few hundred rapidly one after the other, but is there a standard piece of kit that these companies use? Or do they all set up the built-for-purpose rigs themselves in order to carry this out?
Nanoimprint litography is theoretically cheaper and easier than photolitography, so why is there no big player currently pursuing it? Especially given ASML hasn't announced anything for after High-NA EUV, and multiple patterning EUV seems to be already here. Is there any problem with nanoimprint litography that doesnt allow it to be used for bleeding edge semiconductor fabrication?
Assuming the plants are right next to each other and both use FINFET, what happens? Does a whole new team need to work at the new fab which will make chips with a smaller transistor size? Who goes to the new fab?

Many things in this world require semi conductors! Its only a thriving technological world. I am a salesperson at a Large FCA Store (Stellantis) Dealership in the midwest, and we are sitting on less vehicles today for sale in September, 2021 than we had in July, 2021.
Ram trucks factories are shut down right now. Ford trucks are 6 months out. If you want to order a new Cadillac Escalade, expect your new Cadillac to be manufactured next Summer!
With rising demand in Electronics TSMC says has begun construction at its Arizona chip factory site. June 1 (Reuters) - Taiwan Semiconductor Manufacturing Co Ltd (2330.TW) (TSMC) has started construction at a site in Arizona where it plans to spend $12 billion to build a computer chip factory, its chief executive said on Tuesday.
I think we may see a rise in Semi Conductors in the years to come. Everything that requires a button in your car, fire stick remote controller, xbox controller, keyboard etc... requires a semi conductor.
The problem with the vehicle shortage is that the vehicle manufactures planned to schedule less chips in February 2021 for the vehicles of 2021 sales. They thought they would sell less vehicles this year because of the Covid, however, earlier this year, things opened and mask came off. The car manufactures decided to instead order the same amount of chips as they usually do yearly, but the orders were already booked for other manufactures that needed chips. This is why you dont see a shortage in Smart phones, and computers, or TVS. The chip factories are producing chips for them first now before they can produce for car manufactures. It isn't because of a covid factory shut down...
This gives me reason to believe that demand will only increase for Semi Conductors and since TSM holds the most market in this area and they can generally control pricing.
This shows that the demand of current electrical devices int he world is actually far greater than we expected!
