Mu isi y’ibikoresho bya elegitoroniki byo gukora ibikoresho bya semiconductor, gukoresha neza ni itegeko rikomeye. Uko ikoranabuhanga rya chip rigenda rigera mu gihe cya nanometero 2, ndetse no gutandukana gato mu gupima bishobora gutuma ibice byose bya wafers bikurwaho, bigatera igihombo kitagira ingano mu bukungu. Muri iki gihe, "ibipimo" bikoreshwa nk'ibipimo bigira uruhare runini. Nubwo ibipimo gakondo by'icyuma bikoreshwa cyane, bigenda bigaragaza imbogamizi zabyo iyo bihuye n'ibisabwa bikomeye n'inganda za semiconductor mu isuku, kurwanya ingese, no kudahungabana. Ibipimo bya semiconductor, bifite imiterere idasanzwe yabyo mu mubiri no mu bya shimi, birimo kuba "abarinzi batagaragara" mu gupima ibikoresho bya semiconductor, bitanga igisubizo gishya cyo kugabanya amakosa yo gupima.
Uretse Icyuma: Ibyiza Bifatika by'Ibipimo bya Ceramic
Imiterere y’inganda zikora ibikoresho bya semiconductor ishyiraho ibisabwa bikomeye ku bikoresho byo gupima. Nubwo ibyuma bisanzwe bipima, nubwo bifite ubukana buhagije, bishobora kwangirika iyo bishyizwe mu duce tw’ibikoresho igihe kirekire kandi bigakurura uduce twa rukuruzi—akaba ari akaga gakomeye mu gukora wafer yoroheje cyane. Mu buryo bunyuranye, ibyuma bipima neza—cyane cyane ibyakozwe muri zirconia na alumina—bigaragaza inyungu nyinshi.
Ubwa mbere, ibikoresho bya ceramic bifite imiterere karemano ya "zero-injege". Mu byumba by'isuku cyangwa muri laboratwari zigenzura ibikoresho bya semiconductor, ihindagurika ry'ubushuhe ntirishobora kwirindwa. Ibipimo by'icyuma bisaba amavuta kenshi kugira ngo hirindwe ingese, kandi kuba hari agahu k'amavuta bihindura ingano y'igipimo, bigatera amakosa yo gupima. Ibipimo bya ceramic bikuraho burundu iyi ngaruka, bikomeza imiterere y'ubuso ihamye hatabayeho gukenera uburinzi bw'amavuta. Icya kabiri, ceramic si magnetic. Mu igenzura rijyanye n'ibice by'ikoranabuhanga byoroheje, gukurura magnetic bishobora gufata imyanda mito y'icyuma, idakora gusa ubuso bupimye bw'igipimo ahubwo inahumanya ubuso bwa wafer. Ibipimo bya ceramic birinda burundu ingaruka z'ingufu za magnetic, bikerekana ko imyitwarire yo gukoraho ari myiza.
Igikomeye kurushaho, hari ubushobozi bwo kudashira. Ubushakashatsi bwerekana ko ubushobozi bwo kudashira bw'ubuso bw'ibikoresho bya ceramic buruta inshuro zirenga 10 ugereranyije n'ubw'icyuma. Mu gihe cyo kugenzura no kugenzura inshuro nyinshi umunsi ku wundi, ibipimo bya ceramic bigaragaza uburyo buke bwo kuzenguruka, bivuze ko igihe cyo gupima kigenda cyongerwa cyane. Ku miyoboro y'ibikoresho bya ceramic ikora neza cyane, ibi bivuze ko atari ukwizerwa gusa mu gupima, ahubwo ko binagabanya ikiguzi cyo gukoresha mu gihe kirekire.
Guhagarara neza k'ubushyuhe: Uburyo bwo kurwanya ihindagurika ry'ubushyuhe mu kirere
Mu gupima ibintu hakoreshejwe semiconductor, ubushyuhe ni kimwe mu bintu bikomeye bigira ingaruka ku buryo bufatika bwo gupima. Ihindagurika rito cyane mu bushyuhe bwo mu kirere rishobora gutera kwaguka no guhindagurika k'ubushyuhe mu bikoresho by'icyuma, bigatera amakosa yo gupima adasobanutse. Ibikoresho bya semiconductor, cyane cyane semiconductor alumina, bifite coefficient yo kwaguka k'ubushyuhe iri hasi cyane.
Uku guhagarara neza kw'ubushyuhe bituma ibipimo bya ceramic bigumana uburinganire bukomeye mu bipimo bya reference ndetse n'igihe ubushyuhe bwo mu kirere buhinduka—urugero, mu gihe cy'impinduka cyangwa bitewe n'impinduka z'ubushyuhe bwo mu gace runaka mu musaruro. Iyo ibipimo by'icyuma bihinduka bitewe n'ubushyuhe bw'intoki cyangwa impinduka z'ubushyuhe bwo mu cyumba, ibipimo bya ceramic biguma bihamye. Iki kimenyetso ni ingenzi cyane ku igenzura rya semiconductor risaba kugenzura ibikoresho igihe kirekire, gupima ikigereranyo, no gushyira imiterere y'ibikoresho. Bituma reference y'ibipimo ikomeza kuba ihamye haba muri laboratwari igenzura ubushyuhe cyangwa mu iduka aho ibintu bihindagurika cyane, bityo bigahagarika ihererekanya ry'amakosa aterwa n'impinduka z'ubushyuhe aho isoko rituruka.
Isuku no kurwanya ingese: Kumenyera ibidukikije bikabije
Gukora ibikoresho bya semiconductors bikoresha cyane imyuka ya shimi n'imikorere ya plasma, bigatera imbogamizi zikomeye ku buryo ibipimo bihamye. Mu bikorwa nko gushushanya no gushyiramo icyuma gito, ibipimo bisanzwe by'icyuma cyangwa pulasitiki byoroshye kwangirika n'imyuka yangiza, bigatera ubwandu bw'udukoko. Ibikoresho bya ceramic bifite isuku nyinshi (nk'alumina cyangwa silicon nitride bifite ubuziranenge buri hejuru ya 99.6%) bigaragaza ubuziranenge bwa shimi burwanya ingese, bushobora kwihanganira imyuka ishingiye kuri halogen n'ibidukikije bya aside/alkali.
Byongeye kandi, inganda zikora ibikoresho bya semiconductor zigenzura cyane ubwandu bw'udukoko. Ibipimo bya semiconductor, bifite ubuso buto busesenguye neza kugeza ku bukomere bwinshi kandi bunoze, ntibikunze gucika udukoko. Mu gihe cyo kwimura no kugenzura, gukoresha ibikoresho bya semiconductor, ibikombe byo gukurura, cyangwa gushaka udupira birinda neza ivumbi riva mu gukurura ibyuma. Iyi miterere "ifite akamaro mu cyumba gisukuye" ituma ibipimo bya semiconductor bitaba igikoresho cyo gupima gusa ahubwo binarinda ibidukikije bibungabunga amahame agenga ibidukikije mu cyumba gisukuye. Cyane cyane mu bikoresho by'ibanze nka lithography machines na ion implanters, ikoreshwa ry'ibice bya semiconductor rituma icyumba gitunganya ibintu kitagira ubwandu bw'icyuma cya ion, bityo bikarinda umusaruro wa chips.
Gukora no Gutunganya Ibikoresho Byujuje Ubuziranenge: Guharanira Ubuhanga mu Gutunganya Ibikoresho Kuva ku Bikoresho Bikagera ku Bikoresho Birangiye
Guhindura ibyiza by'ibikoresho bya ceramic mu buryo bufatika bwo gupima ntibishobora gutandukanywa n'uburyo bwo gukora neza. Gukora ibipimo bya ceramic byo mu rwego rwa semiconductor ni umushinga uhoraho, usaba kugenzura neza buri ntambwe kuva ku gutegura ifu no gukanda isostatic kugeza ku gukaranga ubushyuhe bwinshi. Urugero, kugira ngo harebwe ko ingano ihamye, umurongo w'ubushyuhe bwo gukaranga ugomba kugenzurwa neza; kunyura mu munota uwo ari wo wose bishobora gutera stress ingana imbere, bityo bigatuma ingano iguma mu buryo burambye.
Mu cyiciro cyo kurangiza, ikoreshwa ry'ibigo bikora ibyuma bifite umurongo 5 hamwe n'ibikoresho bifite diyama bituma uburyo bwo gukora neza kw'ibipimo bya ceramic bugenzurwa ku rwego rwa sub-micron. Ubu buryo bwo gukora neza cyane ntibugaragarira gusa mu buryo bwo kwihanganira ibintu, ahubwo bunagaragarira mu kugenzura ubukana bw'ubuso. Ubuso bwo gupima bunoze ntibugabanya gusa kwangirika gusa, ahubwo bunatuma imbaraga zikwirakwira mu gihe cyo gupima. Muri iki gihe, inganda zashyizeho uburyo buhamye, nka ISO 3650, bugena imiterere y'ubuziranenge (urugero, K, 0, 00) bw'ibipimo bya ceramic, bugenzura ko byujuje ibisabwa byose by'ibikoresho bya semiconductor kuva ku guteranya kwa macro kugeza ku kugenzura kwa micro.
Ibikenewe mu ikoreshwa: Kubaka urusobe rw'ibinyabuzima rupima neza cyane
Uko ikoranabuhanga rya semiconductor rigenda ritera imbere rigana ku nsinga zigezweho z’imikorere, icyifuzo cyo gupima neza kizakomeza kuba kirekire. Uburyo bwo gukoresha ibipimo bya ceramic nabwo burimo kwiyongera, buva ku bipimo gakondo bya gauge na gauge z’impeta kugeza ku bice by’imiterere bito, nk’ibice bikwirakwiza gaze, impeta zo kwibandaho, na chucks za electrostatic. Mu igerageza rya probe card, substrates za silicon nitride ceramic, zifite ubushobozi bwo gutwara ubushyuhe bwinshi n’amashanyarazi, zabaye ibice by’ingenzi bitwara ibihumbi byinshi bya probes zo gupima ikoranabuhanga rigezweho. Mu byiciro bya lithography machine, silicon carbide ceramics, bitewe n’imiterere yazo yoroshye kandi ikomeye, zabaye ibikoresho by’ingenzi byo kugera ku ngendo nziza cyane ku rwego rwa nanometer.
Muri make, ikoreshwa ry'ibipimo bya ceramic mu nganda za semiconductor si ugusimbuza ibikoresho gusa ahubwo ni impinduka mu buziranenge. Mu gukuraho ibintu bibangamira ibintu nko kwangirika, rukuruzi, kwaguka k'ubushyuhe, no kwangirika kw'ibinyabutabire, ibipimo bya ceramic bishyiraho uburyo bwo gupima buhamye kandi bwizewe mu nganda za semiconductor. Mu gihe kizaza, hamwe n'iterambere mu bumenyi bw'ibikoresho n'ikoranabuhanga ryo kubitunganya, ibipimo bya ceramic bizakomeza kugira uruhare runini mu isi ya mikorosikopi, bifasha inganda za semiconductor mu gushaka ubuziranenge burambye.
