Chotetezera kutentha cha SOI pa ma wafer a silicon a mainchesi 8 ndi mainchesi 6 a SOI (Silicon-On-Insulator)

Pokhala ndi gawo lapamwamba la silicon, gawo loteteza oxide, ndi gawo la pansi la silicon, wafer wa SOI wokhala ndi magawo atatu amapereka zabwino zosayerekezeka mu ma microelectronics ndi RF domains. Gawo lapamwamba la silicon, lomwe lili ndi crystalline silicon yapamwamba kwambiri, limathandizira kuphatikiza zida zamagetsi zovuta komanso zolondola komanso zogwira mtima. Gawo loteteza oxide, lopangidwa mwaluso kwambiri kuti lichepetse mphamvu ya parasitic, limawonjezera magwiridwe antchito a chipangizocho pochepetsa kusokoneza kwamagetsi kosafunikira. Gawo lapansi la silicon limapereka chithandizo chamakina ndikuwonetsetsa kuti likugwirizana ndi ukadaulo womwe ulipo wa silicon processing.

Mu ma microelectronics, SOI wafer imagwira ntchito ngati maziko opangira ma circuits apamwamba (ICs) omwe ali ndi liwiro lapamwamba, mphamvu yogwira ntchito bwino, komanso kudalirika. Kapangidwe kake ka magawo atatu kamathandizira kupanga zida zovuta za semiconductor monga CMOS (Complementary Metal-Oxide-Semiconductor) ICs, MEMS (Micro-Electro-Mechanical Systems), ndi zida zamagetsi.

Mu gawo la RF, SOI wafer ikuwonetsa bwino kwambiri pakupanga ndi kukhazikitsa zida ndi machitidwe a RF. Mphamvu yake yotsika ya parasitic, mphamvu yotsika yamagetsi, komanso mphamvu zake zabwino zodzipatula zimapangitsa kuti ikhale malo abwino kwambiri osinthira ma RF switches, ma amplifier, zosefera, ndi zida zina za RF. Kuphatikiza apo, kulekerera kwa radiation kwa SOI wafer kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito paulendo ndi chitetezo komwe kudalirika m'malo ovuta ndikofunikira kwambiri.

Kuphatikiza apo, kusinthasintha kwa SOI wafer kumafikira ku ukadaulo watsopano monga ma photonic integrated circuits (PICs), komwe kuphatikiza kwa zida zamagetsi ndi zamagetsi pa substrate imodzi kuli ndi lonjezo la njira zolumikizirana zama telecommunication ndi deta za m'badwo wotsatira.

Mwachidule, wafer ya Silicon-On-Insulator (SOI) yokhala ndi magawo atatu ndiyotsogola pakupanga zinthu zatsopano mu ma microelectronics ndi ma RF. Kapangidwe kake kapadera komanso magwiridwe antchito ake apadera zimatsegula njira yopitira patsogolo m'mafakitale osiyanasiyana, zomwe zimapangitsa kuti pakhale kupita patsogolo komanso kukonza tsogolo la ukadaulo.
