SOI wafer insulator kuri silicon 8-cm na 6-SOI (Silicon-On-Insulator) wafer

Ibisobanuro bigufi:

Wafer ya Silicon-On-Insulator (SOI), igizwe nibice bitatu bitandukanye, igaragara nkibuye rikomeza imfuruka mubice bya microelectronics hamwe na radio yumurongo wa radio (RF). Iyi abstract irasobanura ibintu byingenzi biranga nibikorwa bitandukanye byubu buryo bushya.

Harimo urwego rwo hejuru rwa silicon, urwego rwa inside ya okiside, hamwe na sisitemu yo hepfo ya silicon, wafer ya SOI ya layer eshatu itanga inyungu ntagereranywa muri microelectronics na domaine ya RF. Igice cyo hejuru cya silicon, kirimo silikoni yo mu rwego rwohejuru, yorohereza guhuza ibice bya elegitoroniki bigoye kandi neza kandi neza. Icyuma gikingira oxyde, cyakozwe muburyo bwitondewe kugirango kigabanye ubushobozi bwa parasitike, cyongera imikorere yibikoresho mukugabanya amashanyarazi adashaka. Hasi ya silicon substrate itanga ubufasha bwubukanishi kandi ikemeza guhuza hamwe na tekinoroji yo gutunganya silikoni.

Muri microelectronics, wafer wa SOI ikora nk'urufatiro rwo guhimba imiyoboro yateye imbere (ICs) ifite umuvuduko mwinshi, imbaraga, kandi kwiringirwa. Ubwubatsi bwayo butatu butuma iterambere ryibikoresho bigizwe na semiconductor bigoye nka CMOS (Complementary Metal-Oxide-Semiconductor) IC, MEMS (Micro-Electro-Mechanical Systems), nibikoresho byamashanyarazi.

Muri domaine ya RF, waI wafer yerekana imikorere idasanzwe mugushushanya no gushyira mubikorwa ibikoresho bya sisitemu na sisitemu. Ubushobozi buke bwa parasitike, imbaraga zo gusenyuka hejuru, hamwe nubwiza buhebuje bwo kwigunga bituma iba substrate nziza kuri RF yahindura, amplifier, filteri, nibindi bikoresho bya RF. Byongeye kandi, kwihanganira imirasire ya SOI wafer itanga uburyo bukwiye bwo mu kirere no mu kirere aho kwizerwa mu bidukikije bikaze.

Ikigeretse kuri ibyo, uburyo bwinshi bwa wafer bwa SOI bugera no ku buhanga bugenda bugaragara nka fotonike ihuriweho n’umuzingi (PICs), aho guhuza ibikoresho bya optique na elegitoronike kuri substrate imwe bitanga ibyiringiro byigihe kizaza cyitumanaho hamwe na sisitemu yo gutumanaho amakuru.

Muncamake, wafer-ibice bitatu bya Silicon-On-Insulator (SOI) wafer ihagaze kumwanya wambere wo guhanga udushya muri microelectronics hamwe na RF ikoreshwa. Imyubakire idasanzwe hamwe nibikorwa bidasanzwe biratanga inzira yiterambere mubikorwa bitandukanye, bigatera imbere kandi bigahindura ejo hazaza h’ikoranabuhanga.
