Muri iyi mpinduramatwara y’ikoranabuhanga, iterambere rikomeye ryo kohereza amakuru riri guterwa n’imikoranire ya telefoni zigendanwa zigezweho, ubunararibonye bwa AR/VR bwimbitse, n’umutwaro munini w’ikoranabuhanga mu kohereza amakuru mu kohereza amakuru mu buryo bworoshye. Uburyo bwa 2D busanzwe—bufite inzira ndende zo guhuza amakuru n’ibihombo byinshi byo kohereza amakuru—ntibushobora kunyura mu mbogamizi z’imikorere.
Kubera iyo mpamvu, gushyira chip stacking no gupakira 3D byagaragaye nk'icyerekezo cy'ingamba z'inganda. Kugira ngo ikoranabuhanga rya 3D rikore neza, ikoranabuhanga rya Through Glass Via (TGV) ryagaragaye cyane kubera ibyiza byaryo bidasanzwe, riva ku bubiko bw'ubushakashatsi n'iterambere rijya mu nganda. TGV ubu irimo kuba ingenzi ku bikoresho by'ikoranabuhanga byo mu gisekuru gitaha.
1. Ikoranabuhanga rya TGV: "Ikiraro" cy'imikoranire ya 3D
1.1 Igitekerezo cy'ingenzi: TGV ni iki mu by'ukuri?
Ishingiro rya TGV ni ugukora microvia zihagaze binyuze mu kirahure. Izi via zikora nk'ibiraro by'amashanyarazi, zihuza ibice cyangwa ibice byashyizwe hamwe, bigatuma habaho kohereza ibimenyetso n'amashanyarazi. Ugereranyije n'insinga zisanzwe za "planar", guhuza imiterere bigabanya cyane inzira zo kohereza kandi bigashyigikira uburyo igikoresho gishyirwamo ibintu bike kandi bigahuza neza.
1.2 Impamvu uduce tw'ikirahure ari two dutwara ibintu bisanzwe bya TGV
TGV irusha TSV (Kunyura kuri Silicon Via) kubera ibyiza bitatu by'ingenzi by'ibirahure:
Ihindagurika ry’amashanyarazi riciriritse - ririnda ibimenyetso bya frequency yo hejuru: Ikirahure gifite uburinganire bwa frequency yo hasi, bigabanya igihombo cya electromagnetic mu gihe cyo kohereza no kubungabunga ubusugire bw’ibimenyetso mu bikorwa bya frequency yo hejuru nka 5G na HPC.
Guhuza ubushyuhe na silikoni - byongera ubwizigirwa: Ikirahure gihuye neza n'ingano ya silikoni mu kwaguka k'ubushyuhe, bigabanya stress ya thermo-mechanical n'inanirwa mu gihe cy'ubushyuhe, bityo bikongera igihe cyo kubaho cy'igikoresho.
Umucyo mwinshi w’urumuri – utuma habaho guhuza optoelectronic: Bitandukanye na silicon idasobanutse, umucyo w’ikirahure ushyigikira porogaramu za electro-optical hybrid. Urugero, muri module za silicon photonics, ikirahure gifasha guhuza amashanyarazi ndetse no kohereza ibimenyetso by’urumuri; muri microdisplay za AR/VR, umucyo ugabanya kuziba kw’urumuri kandi ukongera urumuri n’ubuhanga.
1.3 Kuva kuri TSV kugera kuri TGV: Ihindagurika ry'Ubusanzwe
Mbere ya TGV, TSV yari ikoranabuhanga ryiganje mu guhuza ikoranabuhanga rya 3D. Ariko, TSV ihura n'imbogamizi nyinshi uko ubucucike bw'ikoranabuhanga bwiyongera:
Ikiguzi kiri hejuru: Uburyo bugoye bwo gukata, gusiga ibikoresho mu byuma, no kubitunganya mu buryo bw'icyuma—bituma TSV idakwiye cyane mu nganda nini.
Ibibazo byo kwizera: Kudahuza kw'ubushyuhe hagati ya silikoni n'ibindi bikoresho akenshi bituma ingingo zicika cyangwa zigacika intege.
Ubushobozi buke bwo gukoresha: Silicon yoroshye gukoresha TSV isaba ko porogaramu zikorerwa kuri optoelectronic ziboneka.
TGV ikemura neza ibibazo nk'ibi, ikaba ari yo nzira nziza yo guhuza ikoranabuhanga mu buryo bw'ikoranabuhanga.
2. Binyuze mu gusiga: Umuyoboro w'ibanze utuma TGV ikora neza
2.1 Incamake y'ingenzi: Nta gusiga irangi, TGV ni "Umuyoboro w'imyanda" gusa
Ibyuma by'ikirahure bifasha mu bushyuhe kandi ntibishobora gutwara amashanyarazi. Kugira ngo habeho guhuza, hagomba gushyirwa urwego ruyobora amashanyarazi (ubusanzwe icyuma gifata amatara) ku nkengero z'urukuta. Uru rwego rukora nk'umuhanda w'ikimenyetso - rugena umuvuduko, igihombo, n'ubudahangarwa. Ibyuma bidahuye cyangwa bifite inenge bitera imbaraga nyinshi zo kudahagarara, kudahagarara kw'ibimenyetso, cyangwa se imiyoboro ifunguye, bigatuma binyuze mu gukora ibyuma biba umuyoboro w'ikoranabuhanga rya TGV.
2.2 Imbogamizi: Ingingo ebyiri z'ububabare bukomeye
Igipimo cy'Uburemere Bukomeye
Ubunini bwa TGV buri mu rugero rwa mikorometero (kugeza kuri ~ 30 μm) aho ubujyakuzimu burenga igipimo cya 10: 1. Uburyo gakondo bwo gushyiramo ibintu bugoranye kugera ku butwikiro bwo hasi no ku ruhande rumwe, akenshi bigatuma "uturere twapfuye" tudapfutse neza bigatuma imikorere y'aho duhurira igabanuka.
Kugenzura neza inenge - Umwicanyi wihishe
Inguni n'ibihanamanga binyura mu mpande bishobora kugira imyanda cyangwa uduheri. Ubu busembwa butera imitsi yo mu gace runaka cyangwa imiyoboro ifunguye, bigaca mu buryo butaziguye isano iri hagati y'udupira n'ibikoresho. Bityo, gukumira ubusembwa ni cyo kibazo gikomeye cyo gusiga TGV.
3. Inzira enye zo gusiga: Imbaraga n'imbogamizi
Gutanga umwuka ushyushye (PVD): Bikuze ariko bifite aho bigarukira
Uburyo nko guhumeka no gusohora amazi bitanga firime nziza cyane kandi zifata neza. Ariko, bitewe n'imiterere yayo "y'umurongo ugaragara", PVD ihura n'ibibazo byo gukoresha filime zifite ikigereranyo cyo hejuru kandi zikwiriye filime zifite ikigereranyo kiri munsi ya ~5:1.
Gukuraho umwuka w'ubumara mu buryo bwa "chemical ventilation" (CVD): Ifite ubushobozi bwo hejuru ariko irahenze
CVD ikoresha imyuka ikwirakwira mu mpande, igatanga irangi ringana ndetse no mu miterere y’ibipimo byinshi. Ariko, ubushyuhe bwinshi n’umuvuduko bishobora kwangiza ikirahure, kandi igiciro cy’ibikoresho ni kinini, bigatuma ikoreshwa cyane cyane mu buryo bworoshye.
Gutanga Electrochemical (ECD): Gukora Electrochemical mu bwinshi ku giciro gito
Filimi ziyobora amashanyarazi za ECD zigabanya iyoni z'icyuma zinyuze ku nkuta. Zitanga igiciro gito kandi zitanga umusaruro mwinshi, zikaba nziza cyane mu gukora ingano. Ariko, kugenzura neza ingano ya electrolyte n'ubucucike bw'amashanyarazi ni ngombwa—kunyuramo bigatera firimi zifite imyenge cyangwa kwandura. Ubusanzwe zishyirwa ku miringoti ifite umurambararo wa 5–50 μm.
Gushyira mu byiciro bya atomike (ALD): Igisubizo cy'ubuhanga mu gutunganya ibintu
ALD igenzura ubunini bwa atome kandi ikagira ubushobozi bwo guhuza neza ibintu, bigatuma iba nziza cyane ku bijyanye n'ubunini bw'ibipimo by'ubunini. Ikemura ikibazo cyo gukingira ariko ikagira igipimo gito cyane cyo gushyiramo ibintu hamwe n'igiciro kinini. Bityo, ALD igenewe ahanini indege n'ibikoresho byizewe cyane.
4. Akamaro k'ipamba rya TGV: Gukoresha imikorere ya 3D mu guhuza
Iterambere ry'Umuvuduko - Guhuza Ibinyabiziga mu Muvuduko Winshi
Mu gupakira kuri 2D, ibimenyetso bigomba kugenda intera ndende, bigatuma igihombo cyiyongera. Hamwe no gukoresha metallization ya TGV, uburyo bwo guhuza chip-to-board na chip-to-system buba bugufi, buhagaze, kandi bugatakaza bike. Muri seriveri za HPC, vias za TGV zipfundikiye zituma umuvuduko w'itumanaho rya CPU-to-memory/GPU uzamukaho hejuru ya 30%, bigabanya gutinda no kongera imikorere ya sisitemu.
Gukoresha neza ingufu - Gutinda guke no gukoresha ingufu
Inzira ngufi zo guhuza zigabanya gutinda, mu gihe irangi ridafata imbaraga nyinshi rigabanya ubushyuhe bwa Joule. Urugero, gupakira chips za terefone zigendanwa hakoreshejwe TGV bishobora kugabanya ikoreshwa ry'amashanyarazi ku kigero cya 15–20%, bikongera igihe bateri imara kandi bikongera ubunararibonye bw'umukoresha.
5. Zhenhua Vacuum: Ibisubizo bya TGV Coating byateye imbere
Ibyiza by'Ibikoresho
Gutunganya ibintu mu buryo bwimbitse (Deep-Via Optimization)
Ikoranabuhanga ryo gusiga imbuto mu mwobo wimbitse rituma imbuto zigira urwego rumwe ndetse no mu bipimo bito nka 30 μm bifite igipimo kirenze 10: 1—bikemura kimwe mu bibazo bikomeye cyane mu nganda.
Uburyo bwo gucunga substrate bushobora guhindurwa
Ishyigikira ingano zitandukanye z'ibirahuri, harimo 600 × 600 mm / 510 × 515 mm, hamwe n'uburyo bwo kwaguka kugera ku buryo bunini.
Uburyo bworoshye bwo gukora ibintu – Guhuza ibintu byinshi
Ishyigikira filime ziyobora amashanyarazi n'izikora neza nka Cu, Ti, W, Ni, na Pt, yujuje ibisabwa bitandukanye byo gukoresha mu gutwara amashanyarazi no kurwanya ingese.
Imikorere ihamye no kubungabunga byoroshye
Ifite sisitemu zo kugenzura ibikorwa by’ikoranabuhanga kugira ngo ikurikirane mu buryo nyabwo ubugari bwa filime, hamwe n’igishushanyo mbonera cy’uburyo bworoshye bwo kuyibungabunga no kugabanya igihe cyo kuyihagarika.
Ingano y'Ikoreshwa
Ikoreshwa mu gupfunyika kwa TGV/TSV/TMV, ituma imbuto zishyirwa mu buryo buhamye mu buryo bungana na 10:1.
—Iyi nkuru yasohotse na ibikoresho byo gusiga irangi ry'umwuka uruganda rwa Zhenhua Vacuum
