Umwikorezi wa Epi ni iki?

Gucukumbura Uruhare Rukuru Rwayo muri Epitaxial Wafer Gutunganya

Gusobanukirwa n'akamaro k'abatwara Epi mu Iterambere rya Semiconductor

Mu nganda za semiconductor, umusaruro wa wafers wo mu rwego rwo hejuru (epi) ni intambwe ikomeye mubikoresho byo gukora nka transistor, diode, nibindi bikoresho bya elegitoroniki. Hagati muri iki gikorwa niepi, igikoresho cyihariye cyagenewe gufata wafer neza mugihe cyoherejwe epitaxial. Ariko mubyukuri ni iki gitwara epi, kandi ni ukubera iki ari ngombwa cyane mu gukora igice cya kabiri?

Gukura Epitaxial: Inzira Yingenzi Mubikorwa bya Semiconductor

Gukura kwa Epitaxial, cyangwa epitaxy, bivuga inzira yo kubitsa urwego ruto rwibikoresho bya kristaline kuri wafer ya semiconductor. Iki gipimo, kizwi nka epitaxial layer, gifite icyerekezo kimwe cya kirisiti kimwe na substrate yo munsi kandi ikoreshwa mugutezimbere amashanyarazi ya wafer. Epitaxy ningirakamaro mugukora ibikoresho-bikora cyane bisaba kugenzura neza ibintu bigize imiterere.

Kugirango ugere ku bwiza bwifuzwa no guhuza ibice bya epitaxial, wafers igomba gufatwa neza kandi neza kandi ihamye mugihe cyo kubitsa. Aha nihoepiije gukina.

Uruhare rwabatwara Epi

An epini igikoresho cyabugenewe gifata wafers mugihe cyo kubika epitaxial. Mubisanzwe bikozwe mubikoresho byera cyane bishobora kwihanganira ubushyuhe bwo hejuru hamwe nibidukikije bigira uruhare muri epitaxy. Igishushanyo mbonera cyubwikorezi cyemeza ko wafer ihagaze neza kandi ihuye neza nibikoresho byabitswe, bikavamo igipande kimwe cya epitaxial hejuru yubuso bwose.

Imwe mumikorere yibanze yabatwara epi nugukomeza wafer itajegajega kandi igahuza mugihe cyo kubitsa. Igikorwa icyo ari cyo cyose cyangwa kudahuza bishobora kuganisha ku nenge ziri mu gice cya epitaxial, gishobora kugira ingaruka zikomeye ku mikorere yicyuma cyanyuma. Umwikorezi agomba kandi kwirinda kwanduza kandi akemeza ko wafer ikomeza kutagira uduce cyangwa umwanda mugihe cyo gutunganya.

Impamvu abatwara Epi ari ngombwa mugukora Semiconductor

Ubwiza bwa epitaxial layer bugira ingaruka itaziguye kumikorere yibikoresho bya semiconductor. Nkibyo, uruhare rwabatwara epi ningirakamaro mugushikira amahame yo hejuru asabwa muruganda. Mugutanga ibidukikije bihamye kandi bigenzurwa mugutunganya wafer, umutwara wa epi yemeza ko epitaxial layer yashyizwe muburyo bumwe kandi nta nenge.

Abatwara Epi nabo ni ngombwa mugushigikira ubunini bwinganda zikora. Mugihe igikoresho cya geometrike gikomeje kugabanuka kandi icyifuzo cyo gukora cyane kigenda cyiyongera, gukenera ibikorwa byukuri kandi byizewe bigenda biba ingorabahizi. Abatwara epi yo mu rwego rwo hejuru bafasha abayikora kuzuza ibyo basabwa mugushoboza ibisubizo bihoraho kandi byororoka, nubwo umusaruro wiyongera.

Umwanzuro

Muri make, umutwara wa epi nigikoresho cyingirakamaro mubikorwa byo gukora igice cya kabiri, cyane cyane mukubyara wafita epitaxial. Uruhare rwarwo mu kwemeza umutekano wafer, guhuza, no kurwanya umwanda ni ngombwa kugirango ugere ku rwego rwo hejuru epitaxial layer ikenewe kubikoresho bigezweho bya semiconductor. Mugihe inganda zikomeje gusunika imbibi zikoranabuhanga, akamaro kabatwara epi yizewe kandi ikora neza iziyongera gusa, ibe ikintu cyingenzi mugukurikirana indashyikirwa muguhimba semiconductor.

Kubari mu nganda za semiconductor bashaka kunoza imikorere yabo ya epitaxial, gusobanukirwa no gushora imari mubitwara epi nziza cyane ni intambwe yingenzi yo kugera kubisubizo byiza no gukomeza guhatanira isoko.
