Kodi kudula kwa wafer ndi chiyani?
ndi admin pa 24-10-10
Wafer iyenera kusintha zinthu zitatu kuti ikhale chip yeniyeni ya semiconductor: choyamba, ingot yooneka ngati buloko imadulidwa kukhala wafer; mu njira yachiwiri, ma transistors amalembedwa kutsogolo kwa wafer kudzera mu njira yapitayi; pomaliza, kulongedza kumachitika, ndiko kuti, kudzera mu njira yodulira...

Kugwiritsa ntchito silicon carbide ceramics m'munda wa semiconductor
ndi admin pa 24-10-10
Zipangizo zomwe zimakondedwa kwambiri pazigawo zolondola za makina a photolithography. Mu gawo la semiconductor, zida za ceramic za silicon carbide zimagwiritsidwa ntchito makamaka pazida zazikulu zopangira ma circuit ophatikizika, monga tebulo logwirira ntchito la silicon carbide, njanji zowongolera, zowunikira, chuck yolumikizira ceramic, mikono, ...

Kodi machitidwe asanu ndi limodzi a ng'anjo imodzi ya kristalo ndi ati?
ndi admin pa 24-09-23
Uvuni wa kristalo umodzi ndi chipangizo chomwe chimagwiritsa ntchito chotenthetsera cha graphite kusungunula zinthu za silicon za polycrystalline m'malo opanda mpweya (argon) ndipo chimagwiritsa ntchito njira ya Czochralski kukulitsa makristalo amodzi osasuntha. Amapangidwa makamaka ndi machitidwe otsatirawa: Makina...

Mitundu ingapo ya njira zodulira wafer wa semiconductor
ndi admin pa 24-09-20
Kudula wafer ndi chimodzi mwa zinthu zofunika kwambiri pakupanga ma semiconductor amphamvu. Gawoli lapangidwa kuti lilekanitse molondola ma circuits kapena ma chips ophatikizidwa ndi ma semiconductor wafers. Chinsinsi cha kudula wafer ndikutha kulekanitsa ma chips pawokha ndikuwonetsetsa kuti kapangidwe kake...

Njira ya BCD
ndi admin pa 24-09-18
Kodi njira ya BCD ndi chiyani? Njira ya BCD ndi ukadaulo wophatikiza njira imodzi womwe unayambitsidwa koyamba ndi ST mu 1986. Ukadaulo uwu ukhoza kupanga zida za bipolar, CMOS ndi DMOS pa chip imodzi. Mawonekedwe ake amachepetsa kwambiri dera la chip. Tinganene kuti njira ya BCD imagwiritsa ntchito mokwanira...

Kujambula njira yoyendera ya semiconductor
ndi admin pa 24-09-10
Kuchekedwa koyambirira kwa madzi kunalimbikitsa chitukuko cha njira zoyeretsera kapena kupukutira phulusa. Masiku ano, kuchekedwa kouma pogwiritsa ntchito plasma kwakhala njira yodziwika bwino yochekedwa. Plasma imakhala ndi ma elekitironi, ma cations ndi ma radicals. Mphamvu yomwe imagwiritsidwa ntchito ku plasma imayambitsa ma elekitironi akunja a t...
