CZOCHRALSKI PROCESS OF SILICON WAFERS

Czochralski process is named in conjunction with a Polish scientist called Jan Czochralski, who invented the development in 1916. In the Czochralski process, a seed crystal is dipped into a crucible of molten silicon and withdrawn slowly, pulling a cylindrical single crystal as the silicon crystallizes on the seed. Czochralski process used to produce high volume of Silicon single crystals.

And now I know the proper pronunciation of Czochralski. Thanks!

[@adamallen8922]

+blablabliam probably the only reason im here

[@12tsz12tsz]

Actually, it is wrong pronunciation. Try translate.google.pl/?hl=pl#pl/en/Czochralski

[@OnlyTAS]

Actually, it's more like Tch-oh-ral-ski. I'm Polish, and believe me when I say that Google translate sucks :3

[@eejakobowski282]

it's more like choh-ral-skee, with the "h" pronounced like the ch in "bach" or "loch"

[@dishudishwank5241]

exactly 😂

It's amazing to watch this video after a decade and it's still relevant.

[@jonathanvian2607]

It changed the world

Visual understanding is always more explcit than textbooks

[@alterguy4327]

thanks , i have exam next hour

[@tejasstanley]

Amazing that this process was developed in the 1900s

[@mahipalbishnoi4410]

well explanation in minimum time ,Thanks!!

@wouterdepo
since the seed crystal is monocrystalline it is a lot stronger than normal silicon, so it can handle the weight

[@vip_noob7751]

Chem class laaa watching

[@firstname728]

Thank You Poland for that guy, otherwise we would still use fingers to compute.

You can also " thank " communists for destroying him in 1953. They stripped him of his scientific titles, accused of collaborating with Nazis. He got a heart attack. He could ve achieved even more.

gud one thanks :-)

Hi from 2024👋🏻😊

Doesn't the seed crystal seems to be very small in diameter ?
If you consider the weight of several 100kgs it has to carry.
Or is it just me?

[@jonathanvian2607]

It's just you.

good video

great video

Are you a rapper ? coz damn you're speaking wayyy too fast than Eminem.

[@charlerichie]

gud one pls upload more vidzzz

[@ceasarngoc]

thanks, quite detail

[@yumiequ]

very nice explanation :)

[@moonlight6094]

Get better Mic, for Christ sake.

[@2livenoob]

What is the seed crystal made out of?

[@jasonleearnett]

Bullen Ultrasonics

[@maskedman8368]

but how does it form cylendrical shape just by pulling with that thin seed

[@jonathanvian2607]

They have a crucible (a glass bowl) filled with rocks the seed is cooked into the crystal with the rocks they use DC electrical current to change the state of both crystal seed and silicon rocks.
