Impinduka mu gukata neza wafer! Ni gute wakomeza gushyira ±5um ku ishingiro rya granite?

Mu ntambara ya nyuma ya "nanoprecision" mu nganda za semiconductor, n'ikosa rito cyane mu bikoresho byo gukata wafer rishobora guhindura chip mo imyanda. Ishingiro rya granite ni intwari itaramenyekana igenzura uburyo bwo gushyiramo ±5um, ikandika amategeko yo gukora neza hamwe n'ibitangaza bitatu by'umwimerere.

"Inkingi ihamye" irwanya ubushyuhe: Igipimo cyo kwaguka k'ubushyuhe bwa granite kiri hasi cyane nka 5-7 × 10⁻⁶/℃, bingana na kimwe cya gatatu cy'ibikoresho by'icyuma. Mu gihe cy'ubushyuhe buterwa n'imikorere yihuta y'ibikoresho byo gukata wafer, ibikoresho bisanzwe bizahinduka bitewe no kwaguka no guhindagurika kw'ubushyuhe, bigatuma umutwe wo gukata uhinduka. Ariko, ishingiro rya granite rishobora kuguma "ridakora," bigakuraho cyane cyane guhindagurika kw'ahantu haterwa no guhinduka kw'ubushyuhe no gushyiraho urufatiro rukomeye rwo gukora neza.

"Inkingo itagira icyo ivuga" yo kwinjizwamo ibintu bihindagurika: Urusaku ruhoraho rw'ibikoresho by'imashini n'ihindagurika rihoraho ry'ibikoresho mu iduka bishobora gufatwa nk'"ibica abantu benshi" ku buryo bunoze. Imiterere yihariye ya granite ni nk'icyuma gifata ibintu bihindagurika karemano, gishobora guhindura vuba ibintu bihindagurika byo hanze n'ihindagurika rya mashini riva mu bikorwa by'ibikoresho mo ingufu z'ubushyuhe kugira ngo bishire. Nubwo izindi shingiro zigikomeza "guhindagurika" bitewe no kwijima, ishingiro rya granite ryakoze urubuga ruhamye rw'umutwe ukata rudahinduka, bigatuma ±5um ishoboka.

"Ikihome cy'iteka" kidahura n'ingese: Amaduka akorerwamo ibikoresho bya semiconductor yuzuyemo ibintu byangiza nk'ibisubizo byo gukata no gusukura aside na alkali. Muri ubwo buryo, ishingiro ry'icyuma rizagenda rihinduka ingese no kwangirika buhoro buhoro. Granite, ifite ubushobozi bwo kudahinduka mu binyabutabire, ntabwo ihura n'ibi bintu bya shimi na gato. Uko imyaka yakoreshwa yaba ingana kose, ishobora kugumana imiterere myiza kandi igakomeza gutuma ikata neza.

Kuva ku buhanga bw'ibikoresho kugeza ku gutunganya neza cyane, ishingiro rya granite ryagaragaje mu mbaraga zaryo ko ibikoresho byose bitashobora guhangana n'ibibazo bikomeye byo gukora semiconductor. Kubera izi nyungu zidasanzwe karemano, ishingiro rya granite ryabaye ingenzi ku bikoresho byo gukata wafer kugira ngo bigere ku buryo bwo gusubiramo imiterere ya ± 5um, kandi byarushijeho gutuma inganda za semiconductor zikomeza gutera imbere mu buryo bwo hejuru!
