Inganda za semiconductor zikora ku bushobozi bwazo bwo gupima no gukora. Imiyoboro igezweho irimo transistors zifite uburebure bw'amarembo buri munsi ya nanometero 3 - ingano aho atome imwe ya silikoni ihagarariye igice cy'ingenzi cy'ingano y'ingenzi. Sisitemu za lithography, ibikoresho byo kugenzura wafer, n'ibikoresho bya metrology bikora kandi bigasuzuma iyi miterere bigomba kugera ku buryo bwo gushyira ibintu neza, kwitandukanya n'imitingito, no kudahungabana mu buryo bw'ibipimo byari gusa nkaho bidashoboka mu myaka makumyabiri ishize.
Nyamara muri ibyo byumba byuzuyemo ikoranabuhanga ridasanzwe, kimwe mu bikoresho by'ingenzi by'ubwubatsi ni ikintu cya kera: granite. Granite y'umukara ikoreshwa neza kandi igenzurwa n'ubushyuhe ni yo shingiro ry'imiterere y'ibikoresho byinshi bya semiconductor bigezweho ku isi. Gusobanukirwa impamvu - n'impamvu granite yose idahwanye - bitwereka ikintu cy'ingenzi kandi gikunze kwirengagizwa mu ikoranabuhanga ry'ibikoresho bya semiconductor.
Ibidukikije by'ibikoresho bya semiconductor: Icyo inkingi igomba kubaho
Sisitemu yo kwerekana imiterere y’ibintu mu kirere (scanner cyangwa stepper) ikorera mu cyumba cy’isuku aho umubare w’uduce tw’umwuka ugenzurwa ku rwego rwa 1 cyangwa 10 - bivuze ko uduce turi munsi ya 1 cyangwa 10 kuri metero kibe y’umwuka kuri 0.5 μm cyangwa irenga. Ibikoresho ubwabyo bigomba kugira ubushobozi bwo gusubiramo ahantu haherereye munsi ya nanometero 1, gukoresha neza munsi ya nanometero 2, no gushyira ibintu mu buryo bumwe muri wafer ya mm 300 muri nanometero nke.
Icyiciro cya wafer kigera kuri ibi kigenda ku muvuduko urenze metero 1 ku isegonda, kirushaho kwihuta no kugabanuka ku muvuduko urenze garama 10, kandi kigasubiramo iki gikorwa inshuro ibihumbi mu isaha - buri saha, buri munsi, mu gihe cy'imyaka myinshi. Urufatiro rwa granite rushyigikira iki cyiciro ntirugomba guhindagurika, kwangirika, cyangwa ngo ruvugishe mu buryo bwangiza imiterere y'ikiciro. Kigomba kuguma gihamye mu buryo bungana mu bushyuhe bw'ibikoresho. Kandi kigomba gukora ibi byose mu buryo bwizewe mu gihe cy'ubuzima bwa sisitemu, bushobora kuba imyaka icumi cyangwa irenga.
Ibi si ibintu byoroshye gukora. Bisaba cyane buri gice cy'icyuma - harimo n'ishingiro rya granite risa n'aho ridakora neza.
Gutandukanya no gushonga kw'ingufu: Akamaro k'ingufu za granite
Ibikoresho bya semiconductor bishora imari nyinshi mu kwitandukanya kw'ibintu bihindagurika - kuva ku rufatiro rw'inyubako (zishobora gushyirwa ku byuma bigabanya umwuka) kugeza kuri sisitemu zo guhagarika vibration ku rwego rw'ibikoresho. Ariko izi sisitemu zifite aho zigarukira. Ntizishobora gukuraho vibration zose, kandi ntizishobora guhita zisubiza ku marangamutima yose. Imashini ya granite ikora icyiciro cya nyuma cyo kwitandukanya kw'ibintu bihindagurika.
Fiziki yo kugabanya ubushyuhe bw'amazi mu mihindagurikire ikunda ibikoresho bifite uburemere bwinshi n'ubushobozi bwihariye bwo kugabanya ubushyuhe. Granite yirabura ifite ubucucike bwinshi - hamwe n'imiterere yayo ya kristale ya quartz, feldspar, na mica - itanga uburyo bwiza bwo kugabanya ubushyuhe bw'amazi mu mihindagurikire binyuze mu guhuza ingaruka z'ubucucike n'ubushyuhe bw'ingano. Ubudahangarwa bw'amazi bwinjira mu rufatiro binyuze hasi cyangwa mu mbaraga z'uburyo bwo kugenda bw'ikiciro bushyirwa mu mazi bugashyirwa mu buye mbere yuko busubira mu buryo bwo gupima bwihuse.
Muri urwo rwego, granite irusha icyuma imbaraga nyinshi, nubwo icyuma gifite imbaraga nyinshi zo gukurura. Impamvu iri mu miterere mito ya kristu: imiterere y'ibinyampeke bya granite irasanzara kandi ikanyunyuza ingufu zihindagurika ku mbibi z'ibinyampeke, mu gihe imiterere ya kristu ya kristu ikora neza cyane. Icyuma gishongeshejwe ni cyiza kurusha icyuma cyo gushonga, niyo mpamvu cyakoreshejwe mu mateka mu bikoresho by'imashini - ariko granite igezweho niyo nziza kurushaho.
Guhagarara k'ubushyuhe: Ishingiro ry'ubushobozi bwo gusubiramo nanometero
Ku gipimo cya nanometero, guhagarara k'ubushyuhe ni cyo kintu cy'ingenzi kigenga gusubirwamo kw'ibipimo. Ihindagurika ry'ubushyuhe bwa 1°C mu gice cy'icyuma cya metero 1 ritera kwaguka k'ubushyuhe bwa mikorometero zigera kuri 11.7 - nanometero 11.700. Muri granite, kwaguka guhwanye ni mikorometero 6-8, hafi kimwe cya kabiri cy'icyuma. Mu byuma bya keramike by'ibirahure binini cyane (nka Zerodur cyangwa ULE), ni mikorometero 0-0.02 kuri dogere imwe gusa - ariko ibi bikoresho birahenze cyane kandi biragoye kubitunganya mu bunini bukenewe ku byuma.
Ku bikoresho bya semiconductor, imyitwarire yo kwaguka k'ubushyuhe bwa granite ntigomba kuba iri hasi gusa ahubwo igomba no kuba ishoboka. Abashushanya bakoresha CTE izwi ya granite kugira ngo bahindure uburyo bwo gupima ubushyuhe mu cyiciro.sisitemu yo gupima imyanyaCTE idashobora gusobanurwa cyangwa ihindagurika mu buryo bw'ahantu - ishobora kubaho mu bwiza buke cyangwa mu buryo butanoze bwa granite - ituma kwishyura bidashoboka kandi bigatera amakosa ashingiye ku bushyuhe adashobora gupimwa.
Iyi ni imwe mu mpamvu ituma isoko yihariye n'imiterere ya granite bigira akamaro mu bikoresho bya semiconductor. Ibikoresho bigomba kurangwa n'imyitwarire y'ubushyuhe - ntabwo ari "granite y'umukara" gusa - kandi bigomba kuzuza ibisabwa mu buryo buhamye n'ubucucike buhamye kugira ngo imikorere y'ubushyuhe bwayo ibe imwe mu gice cyose.
Ubuso bwa Granite ifite ikirere: Uburyo bwo kwimuka
Sisitemu nyinshi z’ibikoresho bya semiconductor zikoresha ibyuma bipima umwuka — ibyuma bito by’umwuka urimo umuvuduko bituma ibyiciro bigenda hejuru y’ahantu harebwa nta gukururana na gato kandi nta kwangirika kw’aho bihurira. Ibikoresho bipima umwuka bitanga uburyo bworoshye bwo kugenda muri sub-nanometer, nta buryo bwo gukubita no kunyerera (byangiza imiterere ya nanometer), kandi nta kwanduza amavuta bishobora kwangiza ibidukikije byo mu cyumba cy’isuku.
Imikorere y'icyuma gifata umwuka ishingiye cyane ku buso gicaho. Amakosa yo kugorama ku buso bw'icyuma ahinduka amakosa yo gushyira ku rubyiniro. Ubukana bw'ubuso bugira ingaruka ku kudahinduka kw'icyuma gifata umwuka. Ibikoresho bigomba kuba bikomeye bihagije kugira ngo birwane no kwangirika niba icyuma gifata umwuka cyaguye akanya gato mu gihe cy'ikoreshwa. Kandi ibikoresho bigomba kuba bihuye n'ubushyuhe bw'icyuma gifata umwuka n'uburyo bwo gutanga umwuka kugira ngo hirindwe kwaguka gutandukanye bihindura icyuho cy'umwuka.
Granite nziza, yashyizwe ku rugero rwo hejuru kurusha 1 μm ugereranyije n'intera y'urugendo rw'umuvuduko kandi ikaranze kugeza kuri Ra munsi ya 0.1 μm, yujuje ibi bisabwa byose. Uruvange rw'ubukomere bwinshi (budasaza), ubukana bwo hasi (bushyigikira ibyuma bipima umwuka uhamye), hamwe n'ubudahangarwa bw'ibipimo (bubungabunga ubukana uko igihe kigenda) bituma granite iba ibikoresho bikundwa cyane mu gukoresha imiterere y'umuvuduko mu buryo busaba imbaraga nyinshi.
Igenzura rya Granite muri Wafer n'ibikoresho bya Metrology
Uretse lithography, granite igira uruhare runini mu bikoresho bikoreshwa mu gusuzuma no gupima wafers za semiconductor. Imiterere ya mikorosikopi za elegitoroniki (SEMs), sisitemu ya ion beam (FIB), ibikoresho byo kugenzura inenge y'urumuri, na sisitemu yo gupima hejuru byose byishingikiriza ku rufatiro ruhamye kandi rudahindagurika kugira ngo bigere ku buziranenge bukenewe bwo gupima.
Microscope ya electron scanning (CD-SEM) ipima ubugari bw'irembo rya nanometero 3 igomba gufotora neza. Gutigita kose hagati y'icyitegererezo n'umuraba wa electron mu gihe cyo kubona amashusho bigabanya ishusho kandi bigatera guhindagurika kw'ibipimo. Urufatiro rwa granite rutandukanya icyiciro cy'icyitegererezo n'ihindagurika ry'ubutaka, bigatanga ibidukikije bituje aho gupima ingano ya atome bishoboka.
Mu buryo nk'ubwo, sisitemu zo gupima imiterere y'amatara n'ibikoresho bya geometrike ya wafer bikoresha ishingiro rya granite n'ubuso bw'ifatizo kugira ngo bigumane isano iri hagati y'imiringa yo gupima n'ubuso bwa wafer. Ubuziranenge bw'igipimo cy'igikoresho cyose - ari nabyo bigena niba wafer iranyura cyangwa inaniwe kugenzura - bishingiye ku buryo granite iri munsi yayo ihagaze neza.
Ikoreshwa mu nganda: Ikarita y'igice cya Granite mu nganda zikora ibikoresho bya semiconductor
Kugira ngo umenye neza uruhare rwa granite mu gukora semiconductor, tekereza ku bwoko bw'ibikoresho aho ibice bya granite by'ubuziranenge biboneka buri gihe: scanners za photolithography na steppers (inkingi za wafer stage, reticle stage bases, reference frames); ibikoresho bya chemical mechanical planarization (CMP) (ubuso bw'aho bihagarara, ibice byo gupima); sisitemu zo kugenzura wafer (inkingi za stage, indorerwamo, platforms zo kwitandukanya vibration); ibikoresho bya metrology birimo scatterometers, ellipmeters, n'ibikoresho byo hejuru bya interferometric; sisitemu yo gufata wafer no gutwara aho imiterere y'ibipimo birinda kwangirika kwa wafer; sisitemu yo kugenzura imirasire ya electron na lithography; n'ibikoresho byo gutera ion aho imiterere y'imirasire ari ingenzi cyane.
Muri buri kimwe muri ibi bikorwa, granite si ikintu cy’ingenzi gikoreshwa mu gucuruza ahubwo ni igice cy’ingenzi gipima neza imikorere yacyo kigena neza ubushobozi bwa sisitemu. Itandukaniro riri hagati y’igice cya granite cyakozwe kugeza kuri ± 10 μm ubugari n’ikindi cyakozwe kugeza kuri ± 0.5 μm ubugari si iterambere rya 20 × - rishobora kuba itandukaniro riri hagati y’igikoresho kigera ku bipimo byacyo n’ikindi kidashobora kugera ku bipimo byacyo.
Gushaka Granite nziza yo gukoresha muri Semiconductors
Bitewe n'ibisabwa mu mikorere ya semiconductor, guhitamo no kwemeza impamyabushobozi y'umucuruzi wa granite ni icyemezo gikomeye cy'ubuhanga. Uretse ibipimo by'ibanze by'ibikoresho - ubucucike, coefficient yo kwagura ubushyuhe, urwego rwo kugorora - abaguzi bagomba gusuzuma ubushobozi nyabwo bwo gupima bw'umucuruzi (ese bashobora kwemeza icyo bavuga ko bagezeho?), ubunararibonye bwabo mu gukoresha ibikoresho bya semiconductor, gukomera kwa sisitemu yabo yo gucunga ubuziranenge, n'ubushobozi bwabo bwo kugumana ubwuzuzanye mu byiciro byose by'umusaruro.
Uruhererekane rw'ibikoresho by'inganda za semiconductor ntabwo rubabarira: igice cy'ubuziranenge kitujuje ibisabwa gishobora gutinza itangwa ry'ibikoresho, kwangiza amakuru y'umusaruro, cyangwa bigasaba ko hakorwa ivugurura ry'ubutaka rihenze. Igiciro cy'ishingiro rya granite rihuye n'ibipimo ni gito ugereranyije n'ikiguzi cy'ikiguzi kitahuye n'ibipimo.
