A fagen gwajin semiconductor, zaɓin kayan aikin dandamali na gwaji yana taka muhimmiyar rawa a cikin daidaiton gwaji da kwanciyar hankali na kayan aiki. Idan aka kwatanta da kayan simintin ƙarfe na gargajiya, granite yana zama mafi kyawun zaɓi don dandamali na gwaji na semiconductor saboda ƙwararren aikinsa.
Fitaccen juriya na lalata yana tabbatar da kwanciyar hankali na dogon lokaci
A lokacin aikin gwaji na semiconductor, ana yin amfani da reagents daban-daban na sinadarai sau da yawa, irin su potassium hydroxide (KOH) maganin da aka yi amfani da shi don haɓakar photoresist, da abubuwa masu lalata kamar hydrofluoric acid (HF) da nitric acid (HNO₃) a cikin tsarin etching. Simintin gyare-gyaren ya ƙunshi abubuwa na ƙarfe. A cikin irin wannan mahalli na sinadarai, halayen rage oxidation-reduction na iya faruwa sosai. Ƙarfin zarra suna rasa electrons kuma suna jujjuya halayen ƙaura tare da abubuwan acidic a cikin maganin, yana haifar da lalatawar ƙasa da sauri, haifar da tsatsa da damuwa, da lalata fa'ida da daidaiton girman dandamali.
Sabanin haka, ma'adinan ma'adinai na granite yana ba shi juriya mai ban mamaki. Babban bangarensa, ma'adini (SiO₂), yana da kaddarorin sinadarai masu tsayayye kuma da kyar yake amsawa da acid na gama gari da tushe. Ma'adanai irin su feldspar kuma ba su da ƙarfi a cikin mahallin sinadarai gabaɗaya. Yawancin gwaje-gwajen sun nuna cewa a cikin yanayin gano sinadarai na siminti guda ɗaya, juriyar lalata sinadarai na granite ya fi sau 15 sama da na simintin ƙarfe. Wannan yana nufin cewa yin amfani da dandamali na granite zai iya rage yawan mita da farashin kayan aiki da lalacewa ta hanyar lalata, tsawaita rayuwar kayan aiki, da tabbatar da kwanciyar hankali na dogon lokaci na daidaiton ganewa.
Babban kwanciyar hankali, saduwa da buƙatun daidaiton gano matakin nanometer
Gwajin Semiconductor yana da babban buƙatu don kwanciyar hankali na dandamali kuma yana buƙatar auna daidai halayen guntu a nanoscale. Ƙididdigar haɓakar haɓakar zafin jiki na simintin ƙarfe yana da ɗan ƙaramin ƙarfi, kusan 10-12 × 10⁻⁶/℃. Zafin da aka haifar ta hanyar aiki na kayan aikin ganowa ko jujjuya yanayin zafin jiki zai haifar da haɓakar zafin jiki mai mahimmanci da ƙaddamar da dandamali na simintin ƙarfe, yana haifar da karkatacciyar matsayi tsakanin binciken ganowa da guntu kuma yana tasiri daidaitattun ma'auni.
Matsakaicin haɓakar haɓakar thermal na granite shine kawai 0.6-5 × 10⁻⁶/℃, wanda shine juzu'i ko ma ƙasa da na simintin ƙarfe. Tsarinsa yana da yawa. An kawar da damuwa ta cikin gida ta hanyar tsufa na dogon lokaci kuma canje-canjen zafin jiki ya fi tasiri. Bugu da ƙari, granite yana da ƙarfi mai ƙarfi, tare da taurin 2 zuwa 3 mafi girma fiye da na simintin ƙarfe (daidai da HRC> 51), wanda zai iya tsayayya da tasirin waje da rawar jiki da kyau kuma ya kula da shimfidawa da madaidaiciyar dandamali. Misali, a cikin gano madaidaicin guntu da'ira, dandamalin granite na iya sarrafa kuskuren flatness a cikin ± 0.5μm/m, tabbatar da cewa kayan ganowa na iya samun nasarar gano ainihin nanoscale a cikin mahalli masu rikitarwa.
Fitaccen kayan anti-magnetic, ƙirƙirar yanayin ganowa mai tsabta
Abubuwan lantarki da na'urori masu auna firikwensin a cikin kayan gwaji na semiconductor suna da matukar kulawa ga tsangwama na lantarki. Ƙarfe na simintin gyare-gyare yana da wani matakin maganadisu. A cikin yanayi na lantarki, zai haifar da filin maganadisu da aka jawo, wanda zai tsoma baki tare da siginonin lantarki na kayan ganowa, wanda zai haifar da karkatar da sigina da kuma bayanan gano mara kyau.
Granite, a gefe guda, abu ne na antimagnetic kuma da kyar ba shi da iyaka ta filayen maganadisu na waje. Na'urorin lantarki na ciki suna wanzuwa bibiyu a cikin mahaɗin sinadarai, kuma tsarin yana da ƙarfi, ƙarfin lantarki na waje bai shafe shi ba. A cikin yanayin filin maganadisu mai ƙarfi na 10mT, ƙarfin filin maganadisu da aka jawo akan saman granite bai kai 0.001mT ba, yayin da saman simintin ƙarfe ya kai sama da 8mT. Wannan fasalin yana ba da damar dandamalin granite don ƙirƙirar yanayi mai tsabta na lantarki don kayan ganowa, musamman dacewa da yanayin yanayi tare da tsauraran buƙatu don amo na lantarki kamar gano guntu guntu da gano yanayin da'irar analog mai tsayi, yadda ya kamata yana haɓaka aminci da daidaiton sakamakon ganowa.
A cikin ginin dandamali na gwaji na semiconductor, granite ya zarce kayan simintin ƙarfe gabaɗaya saboda fa'idodinsa masu mahimmanci kamar juriya na lalata, kwanciyar hankali da anti-magnetism. Kamar yadda fasahar semiconductor ke ci gaba zuwa mafi girman daidaito, granite zai taka muhimmiyar rawa wajen tabbatar da aikin kayan gwaji da haɓaka ci gaban masana'antar semiconductor.
