FZ CZ Si wafer iri mudura 12inch Silicon wafer Prime kana Test

Tsananguro pfupi:

Wafer yesilicon ine 12 inch imhando yakatetepa yesemiconductor inoshandiswa mukushandiswa kwemagetsi uye mumaseketi akabatanidzwa. Wafer dzesilicon zvinhu zvakakosha muzvigadzirwa zvemagetsi zvakafanana zvakaita semakombiyuta, maTV nemafoni. Kune mhando dzakasiyana dzewafer uye imwe neimwe ine hunhu hwayo. Kuti tinzwisise wafer yesilicon yakakodzera basa rakati, tinofanira kunzwisisa mhando dzakasiyana dzewafer uye kukodzera kwadzo.

Mawafer Akakweshwa

Mawafer esilicon akakweshwa zvakananga kumativi ese kuti aite girazi. Hunhu hwakanaka hwakadai sekuchena uye kusatsetseka ndihwo hunhu hwakanakisa hwewafer iyi.

MaWafer eSilicon Asina Kubviswa Dope

Dzinozivikanwawo sema "intrinsic silicon wafers". Iyi semiconductor imhando ye silicon yakachena isina dopant mukati mewafer, zvichiita kuti ive semiconductor yakanaka uye yakakwana.

Zvidimbu zveSilicon Zvakaputirwa

Mhando mbiri dzemawafer esilicon ane doped.

Mawafer esilicon ane mhando yeN ane arsenic kana phosphorus. Anoshandiswa zvakanyanya mukugadzira michina yepamusoro yeCMOS.

Mawafer esilicon ane boron doped P-type. Kazhinji, anoshandiswa kugadzira macircuit akadhindwa kana photolithography.

MaWafer eEpitaxial

Mawafer epitaxial ndiwo mawafer anoshandiswa kugadzira pamusoro pechinhu. Mawafer epitaxial anowanikwa ari mawafer akakora uye matete.

Mawafer epitaxial ane layer yakawanda uye mawafer epitaxial akakora anoshandiswawo kudzora kushandiswa kwesimba uye kudzora simba remidziyo.

Mawafer matete epitaxial anowanzo shandiswa mumidziyo yepamusoro yeMOS.

MaWafer eSOI

Mawafer aya anoshandiswa nemagetsi kuvharidzira zvikamu zvitete zve silicon imwe chete kubva muwafer yese ye silicon. Mawafer e SOI anowanzo shandiswa mu silicon photonics uye mu RF applications inoshanda zvakanyanya. Mawafer e SOI anoshandiswawo kuderedza kugona kwemidziyo inoparadzira tupukanana mumidziyo ye microelectronic, izvo zvinobatsira kuvandudza mashandiro.

Sei kugadzira wafer kwakaoma?

Mawafer esilicon ane 12-inch akaoma zvikuru kucheka kana tichitarisa goho. Kunyangwe silicon yakaoma, inopwanyikawo. Nzvimbo dzakakombama dzinogadzirwa sezvo mipendero yewafer yakachekwa inowanzotyoka. Madhisiki edhaimani anoshandiswa kupfavisa mipendero yewafer uye kubvisa chero kukuvara. Mushure mekucheka, mawafer anotyoka nyore nyore nekuti ikozvino ane mipendero yakapinza. Mipendero yewafer yakagadzirwa nenzira yekuti mipendero yakapinza uye isina kusimba inobviswa uye mukana wekutsvedza unoderedzwa. Nekuda kwekushanda kwemupendero, dhayamita yewafer inogadziriswa, wafer inotenderera (mushure mekucheka, wafer yakachekwa inotenderera), uye maburi kana mapurani akatenderedzwa anogadzirwa kana saizi.
