Isigqubutheli se-SOI wafer kwii-wafer ze-silicon ze-SOI (Silicon-On-Insulator) eziyi-8 intshi kunye neziyi-6 intshi

Iquka umaleko we-silicon ophezulu, umaleko we-oxide okhuselayo, kunye ne-substrate ye-silicon esezantsi, i-SOI wafer enamaleko amathathu inika iingenelo ezingenakuthelekiswa nanto kwi-microelectronics nakwiindawo ze-RF. Umaleko we-silicon ophezulu, oquka i-silicon ekristale ekumgangatho ophezulu, unceda ukuhlanganiswa kwezinto ze-elektroniki ezintsonkothileyo ngokuchanekileyo nangokusebenza kakuhle. Umaleko we-oxide okhuselayo, owenziwe ngobuchule ukunciphisa amandla e-parasitic, uphucula ukusebenza kwesixhobo ngokunciphisa ukuphazamiseka kombane okungafunekiyo. I-substrate ye-silicon esezantsi inika inkxaso yoomatshini kwaye iqinisekisa ukuhambelana nobuchwepheshe obukhoyo bokucubungula i-silicon.

Kwi-microelectronics, i-SOI wafer isebenza njengesiseko sokwenza ii-advanced integrated circuits (ICs) ezinesantya esiphezulu, ukusebenza kakuhle kwamandla, kunye nokuthembeka. Uyilo lwayo olunemigangatho emithathu luvumela ukuphuhliswa kwezixhobo ze-semiconductor ezintsonkothileyo ezifana ne-CMOS (Complementary Metal-Oxide-Semiconductor) ICs, i-MEMS (Micro-Electro-Mechanical Systems), kunye nezixhobo zamandla.

Kwicandelo le-RF, i-SOI wafer ibonisa ukusebenza okumangalisayo kuyilo nasekusetyenzisweni kwezixhobo kunye neenkqubo ze-RF. Amandla ayo aphantsi okusasazeka kwe-parasitic, i-voltage ephezulu yokuqhekeka, kunye neempawu zayo zokwahlukanisa ezibalaseleyo zenza ukuba ibe yindawo efanelekileyo yokutshintsha i-RF, ii-amplifier, izihluzi, kunye nezinye izinto ze-RF. Ukongeza, ukunyamezelana kwemisebe ye-SOI wafer kuyenza ifaneleke kwizicelo zeenqwelo moya kunye nezokhuselo apho ukuthembeka kwiindawo ezinzima kubaluleke kakhulu.

Ngaphezu koko, ukuguquguquka kwe-SOI wafer kufikelela kwiiteknoloji ezintsha ezifana neesekethe ezidibeneyo ze-photonic (ii-PIC), apho ukuhlanganiswa kwezinto ezibonakalayo neze-elektroniki kwisiseko esinye kunesithembiso kwiinkqubo zonxibelelwano lwedatha kunye nonxibelelwano lwesizukulwana esilandelayo.

Ngamafutshane, i-wafer ye-Silicon-On-Insulator (SOI) enamaleko amathathu iphambili kwimveliso ezintsha kwi-microelectronics nakwi-RF applications. Uyilo lwayo olukhethekileyo kunye neempawu zayo zokusebenza ezibalaseleyo zivula indlela yokuqhubela phambili kumashishini ahlukeneyo, ziqhuba inkqubela phambili kwaye zibumba ikamva lobuchwepheshe.
