ʻO ka mea hoʻokaʻawale wafer SOI ma nā wafer silicon 8-'īniha a me 6-'īniha SOI (Silicon-On-Insulator)

Me kahi papa silicon luna, kahi papa oxide insulating, a me kahi substrate silicon lalo, hāʻawi ka wafer SOI ʻekolu papa i nā pono like ʻole ma nā microelectronics a me nā kikowaena RF. ʻO ka papa silicon luna, e hōʻike ana i ka silicon crystalline kiʻekiʻe, e hoʻomaʻamaʻa i ka hoʻohui ʻana o nā ʻāpana uila paʻakikī me ka pololei a me ka pono. ʻO ka papa oxide insulating, i hana pono ʻia e hōʻemi i ka capacitance parasitic, hoʻonui i ka hana o ka hāmeʻa ma ka hōʻemi ʻana i ka hoʻopilikia uila makemake ʻole ʻia. Hāʻawi ka substrate silicon lalo i ke kākoʻo mechanical a hōʻoia i ka kūlike me nā ʻenehana hana silicon e kū nei.

I loko o ka microelectronics, lawelawe ka wafer SOI ma ke ʻano he kumu no ka hana ʻana o nā kaapuni hoʻohui holomua (ICs) me ka wikiwiki kiʻekiʻe, ka pono o ka mana, a me ka hilinaʻi. ʻO kāna hoʻolālā ʻekolu-papa e hiki ai ke hoʻomohala i nā mea semiconductor paʻakikī e like me CMOS (Complementary Metal-Oxide-Semiconductor) ICs, MEMS (Micro-Electro-Mechanical Systems), a me nā mea hana mana.

Ma ke kahua RF, hōʻike ka wafer SOI i ka hana kupaianaha i ka hoʻolālā a me ka hoʻokō ʻana o nā polokalamu a me nā ʻōnaehana RF. ʻO kona capacitance parasitic haʻahaʻa, ka voltage breakdown kiʻekiʻe, a me nā waiwai hoʻokaʻawale maikaʻi loa e lilo ia i substrate kūpono no nā kuapo RF, nā amplifiers, nā kānana, a me nā ʻāpana RF ʻē aʻe. Eia kekahi, ʻo ka hoʻomanawanui radiation kūlohelohe o ka wafer SOI e hāʻawi iā ia i kūpono no nā noi aerospace a me ka pale kaua kahi e koʻikoʻi ai ka hilinaʻi i nā ʻano ʻino.

Eia kekahi, ʻo ka versatility o ka wafer SOI e hoʻonui aku i nā ʻenehana e kū mai ana e like me nā photonic integrated circuits (PICs), kahi e hoʻohui ʻia ai nā ʻāpana optical a me nā mea uila ma kahi substrate hoʻokahi e paʻa ai ka hoʻohiki no nā kamaʻilio kelepona a me nā ʻōnaehana kamaʻilio ʻikepili o ka hanauna e hiki mai ana.

I ka hōʻuluʻulu manaʻo, ʻo ka wafer ʻekolu-papa Silicon-On-Insulator (SOI) ke kū nei ma ke alo o ka hana hou i nā microelectronics a me nā noi RF. ʻO kona hoʻolālā kū hoʻokahi a me nā ʻano hana kūikawā e hoʻomākaukau i ke ala no ka holomua ʻana i nā ʻoihana like ʻole, e hoʻokele ana i ka holomua a me ke ʻano o ka wā e hiki mai ana o ka ʻenehana.
