Incazelo
I-Epitaxial Silicon Wafernoma i-EPI Silicon Wafer, iyicwecwe eliwungqimba lwekristalu elenziwe nge-semiconducting elifakwe endaweni ecwebezelayo ye-silicon substrate ngokukhula kwe-epitaxial.Isendlalelo se-epitaxial singase sibe into efanayo ne-substrate ngokukhula kwe-epitaxial okulinganayo, noma isendlalelo esingavamile esinekhwalithi ethile efiselekayo ngokukhula kwe-epitaxial ehlukahlukene, eyamukela ubuchwepheshe bokukhula kwe-epitaxial obuhlanganisa i-chemical vapor deposition CVD, isigaba se-epitaxy LPE, kanye ne-molecular beam. i-epitaxy MBE ukuze kuzuzwe ikhwalithi ephezulu kakhulu yokuminyana okunesici esiphansi kanye nokubamahwashana okuhle kwendawo.Ama-Silicon Epitaxial Wafers asetshenziswa ngokuyinhloko ekukhiqizweni kwamadivayisi athuthukisiwe we-semiconductor, izakhi ze-semiconductor ezididiyelwe kakhulu, ama-IC, ama-discrete namandla, futhi asetshenziselwa isici se-diode ne-transistor noma i-substrate ye-IC efana nohlobo lwe-bipolar, i-MOS kanye namadivayisi we-BiCMOS.Ngaphezu kwalokho, ama-wafers e-silicone e-epitaxial engqimba amaningi kanye nefilimu ewugqinsi ye-EPI avame ukusetshenziswa ku-microelectronics, i-photonics kanye nesicelo se-photovoltaics.
Ukulethwa
I-Epitaxial Silicon Wafers noma i-EPI Silicon Wafer at Western Minmetals (SC) Corporation inganikezwa ngosayizi ongu-4, 5 no-6 intshi (100mm, 125mm, 150mm ububanzi), ngomumo ongu-<100>, <111>, i-epilayer resistivity engu-<1ohm -cm noma kufika ku-150ohm-cm, kanye nogqinsi lwe-epilayer engu-<1um noma kufika ku-150um, ukwanelisa izidingo ezihlukahlukene ekuqedeni okungaphezulu kokwelashwa okuqoshiwe noma kwe-LTO, epakishwe kukhasethi elinebhokisi lebhokisi ngaphandle, noma njengokucaciswa okwenziwe ngokwezifiso kusixazululo esiphelele. .
Ukucaciswa Kwezobuchwepheshe
I-Epitaxial Silicon Wafersnoma i-EPI Silicon Wafer e-Western Minmetals (SC) Corporation inganikezwa ngosayizi we-intshi engu-4, 5 no-6 (100mm, 125mm, 150mm ububanzi), i-orientation engu-<100>, <111>, i-epilayer resistivity engu-<1ohm-cm noma kufika ku-150ohm-cm, kanye nogqinsi lwe-epilayer engu-<1um noma kufika ku-150um, ukuze kwanelise izidingo ezihlukahlukene ekuqedeni okungaphezulu kokwelashwa okuqoshiwe noma kwe-LTO, epakishwe kukhasethi elinebhokisi lebhokisi ngaphandle, noma njengokucaciswa okwenziwe ngokwezifiso ukuze kube nesixazululo esiphelele.
