FZ CZ Si wafer mu stock 12inch Silicon wafer Prime kana Test

Tsanangudzo Pfupi:

A 12 inch silicon wafer chinhu chakatetepa semiconductor chinoshandiswa mumagetsi maapplication uye akabatanidzwa maseketi. Silicon wafers akakosha zvakanyanya muzvigadzirwa zvemagetsi zvakajairika semakomputa, maTV uye nharembozha. Kune mhando dzakasiyana dzewaferi uye imwe neimwe ine yayo chaiyo maitiro. Kuti tinzwisise yakanyatsokodzera silicon wafer kune imwe purojekiti, isu tinofanirwa kunzwisisa akasiyana marudzi ewafer uye kukodzera kwawo.

Polished Wafers

Silicon wafers akakwenenzverwa pamativi ese kuti awane girazi pamusoro. Hunhu hwepamusoro hwakadai sekuchena uye flatness zvinotsanangura zvakanakisa hunhu hwechingwa ichi.

Yakasunungurwa Silicon Wafers

Ivo vanozivikanwawo se intrinsic silicon wafers. Iyi semiconductor ndeye yakachena crystalline fomu yesilicon pasina kuvepo kwechero dopant mukati mewafer, nekudaro ichiita kuti ive yakanaka uye yakakwana semiconductor.

Doped Silicon Wafers

N-mhando uye P-mhando ndiwo marudzi maviri e-doped silicon wafers.

N-type doped silicon wafers ane arsenic kana phosphorus. Inoshandiswa zvakanyanya mukugadzira michina yemhando yepamusoro CMOS.

Boron doped P-mhando silicon wafers. Kunyanya, inoshandiswa kugadzira akadhindwa maseketi kana photolithography.

Epitaxial Wafers

Epitaxial wafers akajairwa wafers anoshandiswa kuwana kuvimbika kwepamusoro. Epitaxial wafers anowanikwa mune dzakakora uye dzakatetepa wafers.

Multilayer epitaxial wafers uye gobvu epitaxial wafers anoshandiswawo kudzora mashandisirwo esimba uye kutonga kwesimba kwemidziyo.

Matete epitaxial wafers anowanzoshandiswa mumhando yepamusoro yeMOS zviridzwa.

SOI Wafers

Aya mawaferi anoshandiswa kuisa nemagetsi matete akaturikidzana eimwe crystal silicon kubva kune yese silicon wafer. SOI wafers anowanzo shandiswa musilicon photonics uye yakakwira performance RF application. SOI wafers anoshandiswawo kuderedza parasitic mudziyo capacitance mune microelectronic zvishandiso, izvo zvinobatsira kuvandudza mashandiro.

Sei kugadzira wafer kwakaoma?

12-inch silicon wafers yakaoma kwazvo kucheka maererano negoho. Kunyangwe silicon yakaoma, zvakare ine brittle. Nzvimbo dzakakasharara dzinogadzirwa semasawn wafer mipendero inowanzotyoka. Madhisiki edhaimondi anoshandiswa kutsvedzerera mipendero yewafer uye kubvisa chero kukuvara. Mushure mekucheka, zvimedu zvinoputika nyore nyore nokuti zvino dzine micheto yakapinza. Wafer edges akagadzirwa nenzira yekuti isina kusimba, inopinza mipendero inobviswa uye mukana wekutsvedza unoderedzwa. Nekuda kwemupendero wekugadzira mashandiro, dhayamita yewaferi inogadziriswa, iyo yakapetwa yakatenderedzwa (mushure mekucheka, iyo yakachekwa yakachekwa ndeye ovha), uye notchi kana ndege dzakatariswa dzinogadzirwa kana hukuru.
