Nkuko imiyoboro ihuriweho yahindutse inganda zigihugu zifatika, ibikoresho byinshi bya semiconductor byakorewe ubushakashatsi kandi bitezwa imbere, kandi Aluminium Nitride ntagushidikanya ko ari kimwe mubikoresho byizewe cyane.
Imikorere ya Aluminium Nitride
Aluminium Nitride (AlN) ifite ibiranga imbaraga nyinshi, irwanya amajwi menshi, imbaraga za insulation nyinshi, coefficente yo kwagura amashyuza, guhuza neza na silikoni, nibindi. Ntabwo ikoreshwa gusa nkimfashanyo yo gucumura cyangwa icyiciro cyo gushimangira ububumbyi bwububiko ahubwo ikoreshwa kandi mubijyanye na ceramic electronique substrate nibikoresho byo gupakira, byagiye bitera imbere mumyaka yashize, kandi imikorere yabyo irenze kure ibya Alumina. Ceramics ya Aluminium Nitride ifite imikorere myiza muri rusange, nibyiza kubutaka bwa semiconductor hamwe nibikoresho byo gupakira, kandi bifite ubushobozi bukomeye bwo gukoresha mubikorwa bya elegitoroniki.
Gukoresha Aluminium Nitride
1. Porogaramu ya Piezoelectric
Aluminium Nitride ifite imbaraga nyinshi, irwanya ubushyuhe bwinshi, hamwe na coefficente yo kwaguka isa na silikoni, nicyo kintu cyiza kubushyuhe bwo hejuru hamwe nibikoresho bya elegitoroniki bifite ingufu nyinshi.
2. Ibikoresho bya elegitoroniki bipfunyika ibikoresho
Oxide ya Beryllium, Alumina, Nitride ya Silicon, na Nitride ya Aluminium ni bimwe mu bikoresho bisanzwe bikoreshwa mu bikoresho bya ceramic.
Mubikoresho bisanzwe byubutaka bushobora gukoreshwa nkibikoresho byubutaka, Ceramics ya Silicon Nitride ifite imbaraga zo guhindagurika cyane, kwihanganira kwambara neza, hamwe nuburyo bwiza bwubukanishi bwibikoresho byubutaka, mugihe coefficente yo kwagura ubushyuhe aribwo buto. Ceramics ya Aluminium Nitride ifite ubushyuhe bwinshi, irwanya ubushyuhe bwumuriro, kandi iracyafite imashini nziza mubushyuhe bwinshi. Birashobora kuvugwa ko, ukurikije imikorere, Aluminium Nitride na Silicon Nitride kuri ubu nibyo bikwiriye gukoreshwa nkibikoresho byo gupakira ibikoresho bya elegitoroniki, ariko kandi bafite ikibazo kimwe: igiciro cyacyo kiri hejuru.
3. Gusaba ibikoresho bitanga urumuri
Kubijyanye no guhinduranya amashanyarazi, nitride ya aluminium (AlN) ifite bande ya semiconductor ya bande itaziguye ya ubugari ntarengwa bwa 6.2 eV, ikaba isumba iy'icyuma kitaziguye. AlN, nkibikoresho byingenzi byubururu na ultraviolet bitanga urumuri, bikoreshwa muri ultraviolet hamwe na ultraviolet yimbitse itanga urumuri, diode ya ultraviolet laser, disiketi ya ultraviolet, nibindi. igisubizo, hamwe nu cyuho cya bande ya ternary cyangwa quaternary alloy irashobora guhindurwa ubudahwema kuva kumurongo ugaragara kugeza kumurongo wa ultraviolet wimbitse, ukabigira ibikoresho byingenzi bikora cyane bitanga urumuri.
4. Gusaba gukuramo ibikoresho
AlN kristal nigikoresho cyiza cya GaN, AlGaN, na AlN epitaxial ibikoresho. Ugereranije na safiro cyangwa SiC substrates, AlN na GaN bifite ubushyuhe bwiza bwo guhuza hamwe no guhuza imiti, kandi imihangayiko iri hagati ya substrate na epitaxial layer ni nto. Kubwibyo, kristu ya AlN nka substrate ya GaN irashobora kugabanya cyane ubwinshi bwinenge mubikoresho no kunoza imikorere yayo, ifite ibyiringiro byiza cyane byo kuyikoresha mugutegura ubushyuhe bwo hejuru, inshuro nyinshi, hamwe nibikoresho bya elegitoroniki bifite ingufu nyinshi. Byongeye kandi, gukoresha kristu ya AlN nkibikoresho bya epitaxial ya AlGaN hamwe nibikoresho bya aluminiyumu (Al) birashobora kandi kugabanya neza ubucucike bw inenge murwego rwa nitride epitaxial kandi bikazamura cyane imikorere nubuzima bwibikoresho bya nitride. Ukurikije AlGaN, umunsi wohejuru wumunsi wimpumyi washyizwe mubikorwa.
5. Gusaba ibikoresho byubutaka nibikoresho byangiritse
Aluminium Nitride irashobora gukoreshwa muburyo bwo gutunganya ceramic; hateguwe Ceramics ya Aluminium Nitride ntabwo ifite imiterere yubukanishi gusa nimbaraga zoroheje kuruta Ceramics ya Al2O3 na BeO, ariko kandi ifite ubukana bwinshi no kurwanya ruswa. Ukoresheje ubushyuhe n’isuri birwanya ubukorikori bwa AlN, birashobora gukoreshwa mugukora umusaraba, ibyokurya bya Al evaporation, na ibindi bice byo hejuru-ubushyuhe bwangirika. Byongeye kandi, Ceramics nziza ya AlN yububiko bwa kirisiti itagira ibara, ifite ibikoresho byiza bya optique, irashobora gukoreshwa nkibumba ryibumba ryibikoresho bya elegitoroniki nibikoresho bya elegitoroniki nibikoresho bya Windows yubushyuhe bwo hejuru cyane hamwe nubushyuhe bwo kurwanya ubushyuhe.
