Isivikelo se-SOI wafer kuma-wafer e-silicon angu-8 intshi kanye nangu-6 intshi e-SOI (Silicon-On-Insulator)

Ihlanganisa ungqimba lwe-silicon oluphezulu, ungqimba lwe-oxide oluvikelayo, kanye ne-substrate ye-silicon engezansi, i-SOI wafer enezingqimba ezintathu inikeza izinzuzo ezingenakuqhathaniswa kuma-microelectronics kanye nama-RF domains. Ungqimba lwe-silicon oluphezulu, olune-crystalline silicon esezingeni eliphezulu, lusiza ukuhlanganiswa kwezingxenye ze-elekthronikhi eziyinkimbinkimbi ngokunemba nokusebenza kahle. Ungqimba lwe-oxide oluvikelayo, oluklanywe ngokucophelela ukuze kuncishiswe amandla e-parasitic, luthuthukisa ukusebenza kwedivayisi ngokunciphisa ukuphazamiseka kukagesi okungafuneki. Ungqimba lwe-silicon oluphansi lunikeza ukwesekwa kwemishini futhi luqinisekisa ukuhambisana nobuchwepheshe obukhona bokucubungula i-silicon.

Kuma-microelectronics, i-SOI wafer isebenza njengesisekelo sokwenziwa kwamasekethe ahlanganisiwe athuthukisiwe (ama-IC) ngesivinini esiphezulu, ukusebenza kahle kwamandla, kanye nokuthembeka. Ukwakhiwa kwayo okunezingqimba ezintathu kwenza kube lula ukuthuthukiswa kwamadivayisi e-semiconductor ayinkimbinkimbi njenge-CMOS (Complementary Metal-Oxide-Semiconductor) ICs, i-MEMS (Micro-Electro-Mechanical Systems), kanye namadivayisi kagesi.

Esizindeni se-RF, i-SOI wafer ikhombisa ukusebenza okumangalisayo ekwakhiweni nasekusetshenzisweni kwamadivayisi nezinhlelo ze-RF. Amandla ayo aphansi okubamba amagciwane, i-voltage ephezulu yokuqhekeka, kanye nezakhiwo ezinhle kakhulu zokuhlukanisa kwenza kube yindawo ekahle kakhulu yokushintsha kwe-RF, ama-amplifier, izihlungi, nezinye izingxenye ze-RF. Ngaphezu kwalokho, ukubekezelela imisebe ye-SOI wafer kuyenza ifanelekele izinhlelo zokusebenza zezindiza nezokuvikela lapho ukuthembeka ezindaweni ezinzima kubaluleke kakhulu.

Ngaphezu kwalokho, ukuguquguquka kwe-SOI wafer kudlulela kubuchwepheshe obusha njenge-photonic integrated circuits (PICs), lapho ukuhlanganiswa kwezingxenye ze-optical neze-electronic ku-substrate eyodwa kunesithembiso sezinhlelo zokuxhumana zesizukulwane esilandelayo kanye nezokuxhumana kwedatha.

Ngamafuphi, i-wafer ye-Silicon-On-Insulator (SOI) enezingqimba ezintathu iphambili ekusungulweni kwezinto ezintsha kwezobuchwepheshe be-microelectronics kanye nezinhlelo ze-RF. Ukwakheka kwayo okuyingqayizivele kanye nezici zayo zokusebenza ezivelele kuvula indlela yokuthuthuka kwezimboni ezahlukahlukene, okuqhuba intuthuko futhi kubumba ikusasa lobuchwepheshe.
