Mavuto a Metallization mu Semiconductor Processing ndi Momwe Mungawathetsere

Kupangidwa kwa zitsulo ndi gawo lofunika kwambiri pakupanga ma semiconductor, kuphatikizapo kupanga maulumikizidwe a zitsulo monga mkuwa kapena aluminiyamu. Komabe, nkhani zokhudzana ndi kupangidwa kwa zitsulo—makamaka kusuntha kwa magetsi ndi kukana kwakukulu kwa kukhudzana—zimabweretsa mavuto akulu pakugwira ntchito ndi kudalirika kwa ma circuits ophatikizidwa.

Zifukwa za Mavuto a Metallization

Mavuto a metallization amayamba chifukwa cha kutentha kosazolowereka komanso kusintha kwa kapangidwe kake panthawi yopanga:

1. Kutentha kwambiri: Pa nthawi ya kutentha kwambiri, ma electromigration a zitsulo amatha kukhala ndi ma electromigration kapena kukula kwa tirigu kwambiri. Kusintha kwa kapangidwe ka zinthuzi kumawononga mphamvu zamagetsi ndikuchepetsa kudalirika kwa ma connection.

2. Kutentha kosakwanira: Ngati kutentha kuli kotsika kwambiri, kukana kukhudzana pakati pa chitsulo ndi silicon sikungatheke, zomwe zimapangitsa kuti magetsi asayende bwino, kugwiritsa ntchito mphamvu zambiri, komanso kusakhazikika kwa makina.

Zotsatira pa Magwiridwe A Chip

Zotsatira zophatikizana za kusamukira kwa magetsi, kukula kwa tirigu, ndi kukana kukhudzana ndi chipangizocho kungachepetse kwambiri magwiridwe antchito a chip. Zizindikiro zake ndi monga kutumiza pang'onopang'ono kwa chizindikiro, zolakwika za logic, komanso chiopsezo chachikulu cha kulephera kugwira ntchito. Izi pamapeto pake zimapangitsa kuti ndalama zokonzera zinthu ziwonjezeke komanso kuti zinthu zichepe.

Mayankho a Mavuto Okhudza Kupangidwa kwa Metallization

1. Kuwongolera Kutentha: Kugwiritsa ntchito njira yowongolera kutentha moyenera, monga kugwiritsa ntchito zida zoziziritsira madzi zamafakitale , kumathandiza kusunga kutentha koyenera. Kuziziritsa kokhazikika kumachepetsa chiopsezo cha kusuntha kwa magetsi ndikuwongolera kukana kwa chitsulo ndi silicon, ndikuwonjezera magwiridwe antchito ndi kudalirika kwa chip.

2. Kukonza Njira: Kusintha zipangizo, makulidwe, ndi njira zoyikamo gawo lolumikizirana kungathandize kuchepetsa kukana kwa kukhudzana. Njira monga mapangidwe a zigawo zambiri kapena kugwiritsa ntchito mankhwala osokoneza bongo ndi zinthu zinazake zimathandizira kuyenda kwa magetsi ndi kukhazikika.

3. Kusankha Zinthu: Kugwiritsa ntchito zitsulo zotsutsana kwambiri ndi ma electromigration, monga zitsulo zamkuwa, ndi zipangizo zolumikizirana zomwe zimathandizira kwambiri monga polysilicon kapena silicides zachitsulo, kungachepetse kwambiri kukana kwa kukhudzana ndikuwonetsetsa kuti zikugwira ntchito kwa nthawi yayitali.

Mapeto

Mavuto a metallization mu kukonza ma semiconductor amatha kuchepetsedwa bwino kudzera mukuwongolera kutentha kwapamwamba, kupanga bwino ma contact, komanso kusankha zinthu mwanzeru. Mayankho awa ndi ofunikira kuti ma chip azigwira ntchito bwino, kukulitsa nthawi ya ntchito, komanso kuonetsetsa kuti zipangizo za semiconductor zikudalirika.
