Nchifukwa chiyani Gawo la Granite Lolondola Kwambiri pa Photolithography Ndi Lofunika Kwambiri pa Microchips za M'badwo Wotsatira?

Munthawi ino ya semiconductor miniaturization, komwe zinthu zimayesedwa mu nanometers, kulimba kwa kapangidwe ka zida zopangira ndikofunikira kwambiri monga momwe gwero lowunikira likuyendera. Pamene kufunikira kwa ma chips amphamvu komanso osagwiritsa ntchito mphamvu zambiri padziko lonse lapansi kukukwera, mainjiniya akuwunikiranso maziko enieni a zinthu zawo zoyera. Nthawi zambiri kukambirana kumayang'ana pa chinthu chimodzi chosasinthasintha: granite wakuda wachilengedwe. Koma chomwe chimapangitsa kutisiteji ya granite yojambulira zithunzichisankho chabwino kwambiri kuposa ma alloys apamwamba kapena ma composites opangidwa pofuna kulondola kwa sub-micron?

Vuto lalikulu mu lithography ndikukhalabe olondola kwambiri panthawi yowunikira komanso kuwonetsa mwachangu. Kugwedezeka kulikonse kwa microscopic kapena kutentha kumatha kubweretsa zolakwika zokulirapo, zomwe zimawononga bwino wafer ya silicon ndikuwononga ndalama zambiri. Kapangidwe ka granite kamene kali ndi kuchuluka kwakukulu komanso kugwedezeka kwapadera kumapangitsa kuti malo azikhala chete komanso opanda phokoso. Mosiyana ndi zitsulo, zomwe zimachita zinthu modziwikiratu koma mozama kwambiri kusinthasintha kwa kutentha, kuchuluka kochepa kwa granite komwe kumawonjezera kutentha kumatsimikizira kuti sitejiyo imakhalabe yokhazikika nthawi yonse yopanga. Kukhazikika kumeneku ndiye maziko enieni omwe makampani onse a semiconductor amamangidwira.

Kuchokera pa sikelo ya nanometer kupita ku dziko lalikulu la kupanga bolodi la ma circuit board losindikizidwa, zofunikira kuti makina akhale olimba zimakhalabe zolimba mofanana.maziko a granite a makina obowola a PCBayenera kupirira kupsinjika kwa makina kosalekeza, kosinthasintha komanso kuthamanga mwachangu. Kuboola kwamakono kwa PCB kumaphatikizapo ma spindles ozungulira pa RPM masauzande ambiri, kuyenda ndi liwiro lodabwitsa kudutsa ndege ya XY. Popanda maziko akuluakulu komanso olimba kuti atenge mphamvu izi za kinetic, kulondola kwa mabowo obowola kungasunthike, zomwe zimapangitsa kuti ma vias asagwirizane bwino komanso kulephera kwamagetsi mu chinthu chomaliza. Pogwiritsa ntchito maziko apamwamba a granite, opanga amatha kupeza mphamvu zambiri popanda kuwononga nthawi yayitali ya makinawo.

Mafotokozedwe aukadaulo nthawi zambiri amafotokoza malire pakati pa gawo lokhazikika ndi yankho lapamwamba. Chimodzi mwazofunikira kwambiri zomwe olamulira a khalidwe aku Europe ndi America amapempha ndi kutha kwa pamwamba.maziko a granite okhala ndi kuuma pamwamba Ra < 0.8μmSikuti ndi chinthu chokongola chabe; ndi chinthu chofunikira kwambiri pakuwongolera mayendedwe apamwamba. Malo osalala oterewa amalola kuphatikiza bwino kwa makina onyamula mpweya, omwe amapezeka paliponse m'magawo apamwamba. Pamene filimu ya mpweya pakati pa siteji ndi maziko ili ndi makulidwe ochepa a ma microns, ngakhale kutuluka pang'ono pamwamba pa granite kungayambitse "kugwa" koopsa, komwe kumabweretsa nthawi yokwera mtengo yogwira ntchito komanso kuwonongeka kwa zida kosatha.

ZHHIMG Group yakhala ikukonza njira zolumikizirana ndi manja zomwe zimafunika kuti zikwaniritse bwino ma sub-micron tolerances amenewa. Ngakhale kuti CNC grinding yamakono imapereka mawonekedwe oyamba, kutsiriza komaliza kwa "Ra < 0.8μm" nthawi zambiri kumachitika chifukwa cha ukatswiri wa anthu komanso kuwongolera kwambiri chilengedwe. Malo athu opangira zinthu amakhala ndi kutentha ndi chinyezi chokhazikika kuti atsimikizire kuti mwalawo ukuyesedwa ndikumalizidwa bwino. Kudzipereka kumeneku pantchito zaluso ndichifukwa chake ZHHIMG yakhala bwenzi lokondedwa la OEM padziko lonse lapansi lomwe silingakwanitse kunyalanyaza kulondola kwa zida zawo.

Poganizira za mtsogolo, ntchito ya granite mumakampani amagetsi ikungokulirakulira. Pamene tikupita ku ma node a process a 2nm ndi 1nm, kulekerera kwa kusalala ndi kukhwima kudzakhala koopsa kwambiri. Makampaniwa sakungofunanso wogulitsa zinthu; akufunafuna mnzake amene akumvetsa ubale wovuta pakati pa sayansi ya zinthu ndi zotulutsa zamakina. Mwa kuphatikiza ma inserts apamwamba, njira zovuta zoyendetsera chingwe, ndi ukadaulo wachiwiri wokutira, ZHHIMG ikusintha granite slab yodzichepetsa kukhala nsanja yotsogola yaukadaulo.

Pomaliza, kaya ndi kulondola kwa moto mwachangu komwe kumafunika kutimaziko a granite a makina obowola a PCBkapena kukhazikika kwa atomiki komwe kumafunika pa gawo la granite kuti ligwiritsidwe ntchito pojambula zithunzi, kusankha zinthu kumakhala komveka bwino. Kapangidwe kachilengedwe ka granite, kakawonjezeredwa ndi uinjiniya wolondola komanso kuuma kwa pamwamba pa Ra < 0.8μm, kumapereka njira yokhayo yopitira patsogolo pa njira zopangira zinthu zovuta kwambiri padziko lonse lapansi. Pamene ukadaulo ukupita patsogolo, ZHHIMG ikudziperekabe kukankhira malire a zomwe zingatheke, kuonetsetsa kuti maziko a dziko la digito amakhalabe olimba ngati mwala.
