Hoʻolauna Kumu: Ke Kuleana o nā Wafers HPSI SiC i nā Aniani AI/AR

ʻO nā wafers Silicon Carbide HPSI (High-Purity Semi-Insulating) he mau wafers kūikawā i hōʻailona ʻia e ke kū'ē kiʻekiʻe (>10⁹ Ω·cm) a me ka haʻahaʻa loa o ka hemahema. I loko o nā aniani AI/AR, lawelawe nui lākou ma ke ʻano he mea substrate koʻikoʻi no nā aniani waveguide optical diffractive, e hoʻoponopono ana i nā bottlenecks e pili ana me nā mea optical kuʻuna e pili ana i nā mea ʻano lahilahi a me ka māmā, ka hoʻolaha wela, a me ka hana optical. No ka laʻana, hiki i nā aniani AR e hoʻohana ana i nā aniani waveguide SiC ke hoʻokō i kahi kahua ʻike ākea loa (FOV) o 70°–80°, ʻoiai e hoʻemi ana i ka mānoanoa o kahi papa lens hoʻokahi i 0.55mm wale nō a me ke kaumaha i 2.7g wale nō, e hoʻonui nui ana i ka ʻoluʻolu o ke komo ʻana a me ka hoʻokomo ʻana i ka ʻike.

Nā ʻano koʻikoʻi: Pehea e hoʻoikaika ai ka mea SiC i ka hoʻolālā aniani AI/AR

ʻO ka Index Refractive kiʻekiʻe a me ka Optical Performance Optical

ʻOi aku ka kiʻekiʻe o ka refractive index o SiC (2.6–2.7) ma mua o ke aniani kuʻuna (1.8–2.0). ʻAe kēia i nā ʻano waveguide lahilahi a ʻoi aku ka maikaʻi, e hoʻonui nui ana i ka FOV. Kōkua pū ka refractive index kiʻekiʻe i ka hoʻopau ʻana i ka "hopena ānuenue" i maʻamau i nā waveguides diffractive, e hoʻomaikaʻi ana i ka maʻemaʻe o ke kiʻi.

Ka Mana Hoʻokele Wela Kūikawā

Me ka conductivity thermal e like me 490 W/m·K (kokoke i ke keleawe), hiki i ka SiC ke hoʻopau koke i ka wela i hana ʻia e nā modula hōʻike Micro-LED. Pale kēia i ka hōʻemi ʻana o ka hana a i ʻole ka ʻelemakule ʻana o ka hāmeʻa ma muli o ke kiʻekiʻe o ka mahana, e hōʻoiaʻiʻo ana i ke ola pākaukau lōʻihi a me ke kūpaʻa kiʻekiʻe.

Ikaika Mekanika a me ke kūpaʻa

ʻO 9.5 ka paʻakikī Mohs o SiC (ʻo ka lua wale nō ma hope o ke daimana), e hāʻawi ana i ke kūpaʻa kūikawā i ke kahakaha ʻana, e kūpono ai no nā aniani mea kūʻai aku i hoʻohana pinepine ʻia. Hiki ke hoʻomalu ʻia kona ʻilikai i Ra < 0.5 nm, e hōʻoia ana i ka pohō haʻahaʻa a me ka hoʻoili kukui like loa i nā alakaʻi nalu.

Ka Hoʻohālikelike ʻana o nā Waiwai Uila

Kōkua ke kū'ē ʻana o ka HPSI SiC (>10⁹ Ω·cm) i ka pale ʻana i ka hoʻopilikia ʻana o ka hōʻailona. Hiki iā ia ke lawelawe ma ke ʻano he mea hana mana kūpono, e hoʻomaikaʻi ana i nā modula hoʻokele mana i nā aniani AR.

Nā Kuhikuhi Noi Kumu

Nā ʻĀpana Optical Core no ke aniani AI/ARs

Nā Aniani Naveguide Diffractive: Hoʻohana ʻia nā substrates SiC e hana i nā waveguides optical lahilahi loa e kākoʻo ana i ka FOV nui a me ka hoʻopau ʻana i ka hopena ānuenue.
Nā Papa Puka Aniani a me nā Prisms: Ma o ka ʻoki ʻana a me ka poli ʻana i hana maʻamau ʻia, hiki ke hana ʻia ʻo SiC i mau puka makani pale a i ʻole nā prisms optical no nā aniani AR, e hoʻonui ana i ka hoʻoili māmā a me ke kū'ē ʻana i ka ʻaʻahu.

Nā Noi Hoʻonui ʻia ma nā Māhele ʻē aʻe

Nā Uila Mana: Hoʻohana ʻia i nā hiʻohiʻona alapine kiʻekiʻe, mana kiʻekiʻe e like me nā mea hoʻohuli kaʻa ikehu hou a me nā mana hoʻokele ʻoihana.
ʻO Quantum Optics: Hana ma ke ʻano he kikowaena no nā kikowaena kala, hoʻohana ʻia i nā substrates no ke kamaʻilio quantum a me nā mea ʻike.

Nā Lawelawe XKH: Nā Hana Hana Hoʻohui a me nā Hiki Hoʻopilikino

Loaʻa i ka hui ʻo XKH nā hiki ke hoʻohui kū pololei mai nā mea maka a hiki i nā wafers i hoʻopau ʻia, e uhi ana i ke kaulahao holoʻokoʻa o ka ulu ʻana o ka substrate SiC, ka ʻoki ʻana, ka poli ʻana, a me ka hana maʻamau. ʻO nā pono lawelawe koʻikoʻi:

Nā ʻano like ʻole o nā mea:Hiki iā mākou ke hāʻawi i nā ʻano wafer like ʻole e like me ke ʻano 4H-N, ke ʻano 4H-HPSI, ke ʻano 4H/6H-P, a me ke ʻano 3C-N. Hiki ke hoʻololi ʻia ke kū'ē ʻana, ka mānoanoa, a me ke kuhikuhi e like me nā koi.
ʻHoʻopilikino ʻana i ka nui maʻalahi:Kākoʻo mākou i ka hana ʻana i nā wafer mai 2-ʻīniha a i 12-ʻīniha ke anawaena, a hiki nō hoʻi ke hana i nā ʻano kūikawā e like me nā ʻāpana huinahā (e laʻa, 5x5mm, 10x10mm) a me nā prism ʻano ʻole.
Mana Hoʻokele Kūpono Papa Optical:Hiki ke mālama ʻia ka Wafer Total Thickness Variation (TTV) ma <1μm, a me ka ʻoʻoleʻa o ka ʻili ma Ra < 0.3 nm, e hoʻokō ana i nā koi pālahalaha nano-level no nā mea hana waveguide.
Pane wikiwiki o ka mākeke:Hoʻomaopopo ka hoʻohālike ʻoihana i hoʻohui ʻia i ka hoʻololi kūpono mai ka R&D a i ka hana nui ʻana, e kākoʻo ana i nā mea āpau mai ka hōʻoia liʻiliʻi a hiki i nā hoʻouna nui (ʻo ka manawa alakaʻi maʻamau he 15-40 mau lā).

Nā nīnau i nīnau pinepine ʻia no ka HPSI SiC Wafer

Q1: No ke aha i manaʻo ʻia ai ʻo HPSI SiC he mea kūpono no nā aniani waveguide AR?
A1: ʻO kona helu kuhikuhi refractive kiʻekiʻe (2.6–2.7) e hiki ai i nā ʻano waveguide lahilahi a ʻoi aku ka maikaʻi e kākoʻo ana i kahi kahua ʻike nui aʻe (e laʻa, 70°–80°) me ka hoʻopau ʻana i ka "hopena ānuenue".
Q2: Pehea e hoʻomaikaʻi ai ʻo HPSI SiC i ka hoʻokele wela i nā aniani AI/AR?
A2: Me ka conductivity thermal a hiki i 490 W/m·K (kokoke i ke keleawe), hoʻopuehu pono ia i ka wela mai nā ʻāpana e like me Micro-LEDs, e hōʻoiaʻiʻo ana i ka hana paʻa a me ke ola lōʻihi o ka hāmeʻa.
Q3: He aha nā pono paʻa o ka HPSI SiC no nā aniani hiki ke hoʻokomo ʻia?
A3: ʻO kona paʻakikī koʻikoʻi (Mohs 9.5) e hāʻawi i ke kūpaʻa kiʻekiʻe loa i ke kahakaha ʻana, e hoʻolilo ana ia i mea paʻa loa no ka hoʻohana ʻana i kēlā me kēia lā i nā aniani AR papa mea kūʻai.
