Dhaimani Wire Wire Kucheka Tekinoroji inozivikanwawo sekubatanidzwa kwekubatanidza brasive yekucheka tekinoroji. Iko kushandiswa kweElectroplating kana Resin Boging Nzira yeDiamondi Yakasimbiswa pamusoro peSimbi Wire, Diamondi Wire Kuisa Pamusoro peSilicon tsvimbo kana Silicon ingot kugadzira kugeda, kuti uwane mhedzisiro yekucheka. Dhaimani Wire Kucheka kwehunhu hwehunhu hwekukurumidza kucheka kumhanya, kukwira kwakadzika kwekunyatsojeka uye kurasikirwa kwezvinhu zvakaderera.

Parizvino, iyo imwe crystal musika waya wedhaimani yekucheka silicon yakagamuchirwa, asi yakasangana nayo mukusimudzira, pakati peiyo Velvet White dambudziko rinonyanya kuzivikanwa. Tichifunga nezveizvi, pepa iri rinotarisisa maitiro ekudzivirira diamondi waya yekucheka monocrystalline

Maitiro ekuchenesa wedhaimani waya yekucheka Monocrystalline silicon Wafer Wafer Iyo yekuchenesa michina inonyanya kuve pre-yekuchenesa muchina (Dhidemming muchina) uye muchina wekuchenesa. Maitiro makuru ekuchenesa emuchina wepamberi-pre-kuchenesa Maitiro makuru ekuchenesa emushini wekuchenesa ndewekuchenesa

Nheyo yeiyo imwe-crystal velvet kugadzira

Monocrystalline Silicon Wafer ndiye hunhu hweAnisotropic Corros of Monocrystalline Silicon Wafir. Iyo nzira yekuita ndiyo inotevera yemakemikari yekuita eacation:

Si + 2naoh + H2O = NA2SIO3 + 2H2 ↑

Mune hunhu, iyo Suede Foration maitiro ndeyekuti: NAHOO Solution yehuremu hwakasiyana hwekristaro, (100) Corros Inomhan'ara " . Mushure mekunge chimiro chaumbwa, kana chiedza chakaitika kune imwe kasha, iyo mwenje icharatidzwa kune imwe nzvimbo kune imwe kona, ichiita kuti gadziriswe, nokudaro ichidzora kuratidzwa kweiyo silicon wafer , ndiko kuti, iyo mwenje wechiedza mhedzisiro (ona Mufananidzo 2). Iyo iri nani saizi uye kufanana kwe "piramidhi" chimiro, zvakanyatsojeka chigadziko chemhedzisiro, uye pasi pechiso chinomiririra silicon wafer.

Kuongororwa kweimwe crystal kuchena

Nekutarisa Electron Microscope pane chena silicon yeSilicon yeiyo chena yakaumbwa munzvimbo iyi yaisanyudzwa, uye nzvimbo yacho yairatidzika kuva neyakagadzirirwa Munzvimbo chena yeiyo yakafanana silicon wafer yakaumbwa zviri nani (ona Mufananidzo 3). Kana paine zvasara pamusoro peMonocrystalline Silicon Wafer nharaunda ine yakakwirira kuratidza yakafananidzwa nenzvimbo yakajairika mune inoonekwa yakaratidzwa seyakachena. Sezvatinogona kuoneka kubva kuzvimbo yekuparadzira yenzvimbo chena, haisi yenguva dzose kana yakajairwa chimiro munharaunda yakakura, asi munzvimbo chete. Izvo zvinofanirwa kunge zviri zvekuti pllutants yemuno pamusoro peiyo silicon waffer haina kucheneswa, kana mamiriro ekunze eSilicon Wafer anokonzerwa nekusvibiswa kwechipiri.
