Sapphire Square Blank Substrate – Ikoranabuhanga, Ikoranabuhanga, n'Igerageza rya Wafer

Ishusho y'agace k'ubusa ka Sapphire Square – Ishusho y'urumuri rw'amatara, iy'ibice bibiri, n'iy'ikizamini

Ibisobanuro bigufi:

Igice cy'ubuso cya safiro kigaragara ku ishusho ni ibikoresho bifite isuku nyinshi, bifite icyuma kimwe cya aluminiyumu (Al₂O₃), byakozwe kugira ngo bihuze n'ibikenewe cyane mu buryo buhanitse bw'urumuri, gutunganya ibikoresho bya semiconductor, no gupima ibikoresho by'ubuhanga. Byakozwe binyuze mu buryo buhanitse bwo gukuramo kristu nka Kyropoulos (KY) cyangwa Czochralski (CZ), iki gice cy'ubuso cya safiro kigaragaza ubwiza budasanzwe bw'urumuri, ubukana budasanzwe, n'ubudahangarwa butangaje bwa shimi, bigatuma kiba amahitamo meza yo gukoreshwa mu nganda zikora neza.

Incamake y'agace k'ubusa ka Sapphire Square

Igice cy'ubusa cya safiro, nk'uko bigaragara ku ishusho, ni igice cy'ubusa bwa aluminiyumu imwe (Al₂O₃) gifite isuku nyinshi cyagenewe gukoreshwa mu buhanga buhanitse bw'amatara, gukora ibikoresho bya semiconductor, no gupima ibikoresho by'ubuhanga. Iyi safiro izwiho imiterere yayo idasanzwe y'umubiri n'imiti, yabaye kimwe mu bikoresho by'ingenzi cyane mu nganda zisaba kuramba cyane, gutuza, no gukora neza kw'amatara. Yakozwe binyuze mu buryo bugezweho bwo gukuramo kristu, nka Kyropoulos (KY), Ubushyuhe bwo Guhinduranya (HEM), cyangwa Czochralski (CZ), iyi myanya y'ubusaro ikorwa neza kugira ngo yuzuze amahame meza cyane.

Ibintu by'ingenzi bigize Sapphire Square Blank Substrate

Safiro ni kristu ifite imiterere ya anisotropic imwe, ifite imiterere ya hexagonal, itanga uruvange rudasanzwe rw'imbaraga za mekanike, ubushyuhe buhamye, no kudahinduka kw'imiti. Ifite igipimo cya Mohs cya 9, safiro ni iya kabiri nyuma ya diyama mu kurwanya gushwanyagurika, ikaba ikomeza igihe kirekire nubwo haba mu nganda zikora ibintu biremereye. Aho ishongesha harenze 2000°C, bigatuma ikora neza mu bidukikije birimo ubushyuhe bwinshi, mu gihe igihombo cyayo gito cya dielectric gituma iba igikoresho cyiza cyane cyo gukoresha RF no gukoresha ikoranabuhanga rigezweho.

Mu gice cy’urumuri, safiro igaragaza uburyo bwo kohereza amakuru kuva kuri ultraviolet yimbitse (~200nm) kugeza ku isura igaragara kugeza kuri infrared yo hagati (~5000nm), ifite uburyo bwo guhuza neza bw’urumuri n’ubushyuhe buke iyo irebeshejwe neza. Iyi miterere ituma ahantu hagaragara kare ha safiro ari ingenzi mu bintu bikoresha ikoranabuhanga rya optique nka sisitemu za laser, fotoniki, spectroscopy, na imaging.

Gukora no Gutunganya

Buri gice cy’ubuso cya safiro gifite ubuso butagira ibara kinyura mu nzira ikomeye yo gukora, gitangirana n’ifu y’ubutare ya alumina isukuye cyane ishyirwa mu icupa rigenzurwa rya kristu mu itanura rishyushye cyane. Nyuma y’uko kristu nyinshi ikuze, iba ifite icyerekezo cyiza (ubusanzwe C-plane (0001), A-plane (11-20), cyangwa R-plane (1-102)) kugira ngo ihuze n’ibisabwa byihariye. Hanyuma kristu icibwamo uduce duto tw’ubuso hakoreshejwe inkero za diyama, hagakurikiraho gukoresha neza uburyo bwo gusimbuza kugira ngo habeho ubugari bungana. Ku bijyanye n’ikoreshwa ry’amatara n’iry’imirongo, ubuso bushobora gusigwa neza ku rwego rwa atome, buhuye n’imiterere ikomeye, ubugari, n’imiterere y’ubuso.

Ibyiza by'ingenzi

Umucyo udasanzwe w'amashusho– Kohereza imiyoboro miremire kuva kuri UV kugera kuri IR bituma iba nziza cyane ku madirishya y’urumuri, imiyoboro ya laser, n’ibifuniko by’amasensa.
Imbaraga z'ubukanishi zihebuje– Ingufu nyinshi zo gukanda, gukomera kw'ivunika, no kudacika intege bitanga ubuzima bwiza mu bice bifite stress nyinshi.
Guhagarara neza mu bushyuhe n'imiti– Irwanya ubushyuhe, ubushyuhe bwinshi, n'ibinyabutabire bikomeye, ikomeza ubuziranenge mu gihe cyo gutunganya ibikoresho bya semiconductor ndetse no guhura n'ibidukikije bikomeye.
Igenzura ry'ibipimo neza– Ubunini bushoboka bwo kwihanganira ubugari buri hagati ya ± 5µm n'ubugari bw'ubuso kugeza kuri λ/10 (kuri 632.8nm), ni ingenzi cyane mu gukoresha fotolithography na wafer bonding.
Guhindagurika– Bikwiriye gukoreshwa mu buryo butandukanye harimo ibice by’urumuri, substrates zo gukuraho epitaxial, na wafers zo gupima imashini.

Porogaramu

Porogaramu zo Gukoresha Ikoranabuhanga: Ikoreshwa nk'amadirishya, filters, laser gain medium holders, ibifuniko birinda sensors, na fotonics substrates bitewe n'uko igaragara neza kandi iramba.
Ibice by'ingufu bya semiconductor: Ikora nk'ishingiro ry'amatara ya LED ashingiye kuri GaN, ibikoresho by'ikoranabuhanga (imiterere ya SiC-on-saphire), ibikoresho bya RF, n'imiyoboro ya microelectronic, aho ubwiyongere bw'ubushyuhe n'ubudahangarwa bw'imiti ari byo by'ingenzi.
Ikizamini cy'ibikoresho n'udukombe tw'udupfunyika: Ikoreshwa cyane nk'ibikoresho byo gupima mu miyoboro y'ibikoresho bya semiconductor, bikoreshwa mu gupima imashini, kwigana imikorere, no gupima uburambe bw'ibikoresho byo gushushanya, gushyiramo, cyangwa kugenzura.
Ubushakashatsi bwa Siyansi: Ni ngombwa mu gushyiraho igerageza bisaba urubuga rudakora, rubonerana, kandi ruhamye mu ikoranabuhanga kugira ngo habeho inyigo z'amatara, amashanyarazi n'ibikoresho.

Ibibazo Bikunze Kubazwa

Q1: Ni iyihe nyungu yo gukoresha safiro ifite impande kare hejuru y'agace k'uruziga?
A: Ahantu hafite impande kare hatanga ahantu ntarengwa ho gukamura, gukora ibikoresho, cyangwa gupima imashini, bigabanyiriza imyanda y'ibikoresho n'ikiguzi.

Q2: Ese substrates za safiro zishobora kwihanganira ibidukikije byo gutunganya semiconductor?
A: Yego, substrates za safiro zigumana ubushyuhe bwinshi, gushushanya plasma, no kuvurwa hakoreshejwe imiti isanzwe mu gukora semiconductor.

Q3: Ese icyerekezo cy'ubuso ni ingenzi mu ikoreshwa ryanjye?
A: Yego rwose. Safira ya C-plane ikoreshwa cyane muri GaN epitaxy mu gukora LED, mu gihe icyerekezo cya A-plane na R-plane ari byo bikundwa mu bikorwa byihariye bya optique cyangwa piezoelectric.

Q4: Ese ibi bipfundikizo biboneka hamwe n'amabara yihariye?
A: Yego, irangi rirwanya urumuri, dielectric, cyangwa conductive coating rishobora gushyirwaho kugira ngo rihuze n'ibisabwa byihariye by'ikoranabuhanga cyangwa iby'ikoranabuhanga.
