Silicon Wafer Processing Animation

chocolate wafers

what the fuck did i just watch

[0ElectroMad0]

Great .. thank you :)

[lintangdhea]

khosrow1 can you please add the steps on this process? great video anyway

[jpmorgan187]

kewl vid

[CabalaCicero]

At 1:00 what is it being sprayed on the wafer? Thanks!

[douro20]

@CabalaCicero

It is showing a CVD or chemical vapor deposition process used to dope the wafer. Silicon wafers can be produced as pure (undoped), n-type, or p-type.

[CabalaCicero]

@douro20 ah thanks for the clarification. I kinda know what you're talking about, I had material science lectures in uni.

[Aiyoros]

Music sounds like Vangelis

nice explanation btw :)

[sacrednune]

This is my job. Finally I can show people what it is I do. Thank you!

[afakethrum]

What is being sprayed onto the surface of wafer at the last step?

[HeadShot360IN]

what music is that??? sounds cool

[happygamestvfun1]

whats silicon and whats a waffer

[HeadShot360IN]

@happygamestvfun1 silicon is a type of crystal found mixed with sand. a wafer is a really thin sheet, sorta like a cracker, but in this case it's made of silicon

[nasoszeppos]

what's with the idiotic cheesy music?????

[cbaker9552]

Check us out University Wafer

[cantbefooled]

Cool stuff ...

[cashmonyxxx]

what is that song>

From the movie The Bounty?

[Lailani2000]

How much is the tuition for this school? do they provide a certificate or degree?

[melpy90]

nice vid !! ;)

[VadimCC]

Thank you for that video!

But what is the last stage with brown vapor?

[mohsun123]

@VadimCC that is a mix of special chemicals that harden when exposed to UV light. the chip design is shone on to the surface and the chemical hardens where the light hits.

[VadimCC]

Thanks a lot! But why? Doesn't it adds impurities to the substrate?

[mohsun123]

no actually it doesn't. they have a special method of doing it which makes this such a interesting process. i cant really explain it here but you should check out the video " how computer chips are made". it is a very helpful little video which can answer a few of your questions. :D

[mohsun123]

i was just checking they do add impurities to make the silicon change its electrical properties. the impurities are added if any change is necessary in the electric property of the chip.

[xsoccerdanx66]

this is such a cute vid. really inspired me? i love it when machine work on time<3

[adisharr]

Great animation - very informative :)

[666TwistedFuck666]

ah yes,i finally got it^^

thank you very much:)

[khosrow1]

You are welcome. I am glad this was helpful.

[hardstyle905]

This is a very, very good video! Thank you!

I have one question.

I ordered a unused silicon wafer off ebay and I'd like to make a bipolar transistor. (Note: Just ONE! I think that ought to be possible to accomplish at home...)

Well, I don't really know how to dope the silicon so that a certain area becomes n-type and another area p-type? I read on wikipedia they do it with ion cannons. Of course I dont have one of those though lol. Are there any other ways?

[khosrow1]

Thank you very much for your kind comment. Doping silicon requires special equipment.

ROFL LOLMAO PMSL HAHA

duh

[muzammilali007]

dear it can't be done at home

[1NX9]

@hardstyle905

"I think that ought to be possible at home"

You must be kidding?!

First understand the Basics of microelectronics manufacturing.

For instance you require absolute sterile rooms (free from any dust particles) to create even a chip. Which also mean suiting up in special suits.

Then you require various chemicals.

Then you require numerous special equipment eg Chemical Vapour Deposition (CVD) machinery.

Then you require special photographic equipment and chemicals.

etc.

Hi Khosrow1, I sent you a message about your animation

[khosrow1]

Thank you for the link.

Khosrow

[MrBob11235813]

I wish the video told me what was happening and the names of the steps.

[khosrow1]

You are very welcome. I am glad that the video was informative for you.

[redkerri]

thanks a lot

it let me know how wafer made

[trader891]

Very well done.

[wrumj]

thank you for this video....
