Wafer ɗin FZ CZ Si yana cikin hannun jari na inci 12 na Silicon wafer Prime ko Test

Takaitaccen Bayani:

Wafer ɗin silicon mai inci 12 wani sirara ne na semiconductor da ake amfani da shi a aikace-aikacen lantarki da kuma da'irori masu haɗawa. Wafer ɗin silicon suna da matuƙar muhimmanci a cikin kayayyakin lantarki kamar kwamfutoci, talabijin da wayoyin hannu. Akwai nau'ikan wafer daban-daban kuma kowannensu yana da takamaiman halayensa. Domin fahimtar wafer ɗin silicon mafi dacewa ga wani aiki na musamman, ya kamata mu fahimci nau'ikan wafer daban-daban da kuma dacewarsu.

Wafers masu gogewa

Wafers na silicon waɗanda aka goge musamman a ɓangarorin biyu don samun saman madubi. Halaye masu kyau kamar tsarki da lanƙwasa suna bayyana mafi kyawun halaye na wannan wafer.

Wafers ɗin Silicon da ba a taɓa shan su ba

Ana kuma san su da wafers na silicon. Wannan semiconductor wani nau'in silicon ne mai tsarki ba tare da kasancewar wani dopant a cikin wafer ba, don haka ya sa ya zama semiconductor mai kyau da cikakke.

Wafers ɗin Silicon da aka Doped

Nau'in N da nau'in P sune nau'ikan wafers guda biyu na silicon da aka yi wa ado da doped.

Wafers ɗin silicon da aka yi wa ado da nau'in N-type suna ɗauke da arsenic ko phosphorus. Ana amfani da shi sosai wajen ƙera na'urorin CMOS na zamani.

Wafers ɗin silicon mai nau'in P-type na Boron. Galibi, ana amfani da shi don yin da'irori da aka buga ko kuma photolithography.

Wafers na Epitaxial

Wafers na Epitaxial wafers ne na gargajiya da ake amfani da su don samun daidaiton saman. Wafers na Epitaxial suna samuwa a cikin wafers masu kauri da siriri.

Ana kuma amfani da wafers ɗin epitaxial masu layi da yawa da kuma wafers masu kauri na epitaxial don daidaita yawan amfani da makamashi da kuma sarrafa wutar lantarki na na'urori.

Ana amfani da ƙananan wafers na epitaxial a cikin kayan aikin MOS masu kyau.

Wafers na SOI

Ana amfani da waɗannan wafers don rufe layukan silicon guda ɗaya ta hanyar lantarki daga dukkan wafer silicon. Ana amfani da wafers na SOI a cikin silicon photonics da aikace-aikacen RF mai ƙarfi. Hakanan ana amfani da wafers na SOI don rage ƙarfin na'urorin parasitic a cikin na'urorin lantarki na microelectronic, wanda ke taimakawa wajen inganta aiki.

Me yasa ƙera wafer yake da wahala?

Wafers ɗin silicon mai inci 12 suna da matuƙar wahalar yankewa dangane da yawan amfanin ƙasa. Duk da cewa silicon yana da tauri, yana kuma da rauni. Ana ƙirƙirar wurare masu tauri saboda gefunan wafer da aka yanka suna karyewa. Ana amfani da faifan lu'u-lu'u don sulke gefunan wafer da kuma cire duk wani lahani. Bayan yankewa, wafers ɗin suna karyewa cikin sauƙi saboda yanzu suna da gefunan kaifi. An tsara gefunan wafer ta yadda za a kawar da gefunan masu rauni da kaifi kuma damar zamewa ta ragu. Sakamakon aikin samar da gefunan, ana daidaita diamita na wafer ɗin, wafer ɗin yana zagaye (bayan yankewa, wafer ɗin da aka yanke yana da siffar oval), kuma ana yin ko girma ko ma'auni ko kuma ma'auni.
