Mu nsi enzibu ennyo ey’okukola semikondokita, ng’okukozesa ebintu kubaawo ku minzaani ya atomu, okuteekebwamu ion kuyimiridde nga tekinologiya ow’ejjinja ery’oku nsonda. Enkola eno, ekuba ddala bbomu za silikoni wafers ne dopant ions okusobola okulongoosa eby’amasannyalaze byabwe, yeesigamye ku ntandikwa enkulu: okutondebwawo kw’ekitangaala kya ion ekirongoofu, ekinywevu. Ku mutima gwennyini ogw’ensibuko ya ion-yingini y’ensengekera eno enzibu-waliwo ekitundu ekirimu obugumu wansi w’embeera ezisukkiridde: ekiwujjo kya tungsten.
Waya eno entonotono eriko enkokola, mu butuufu, kyewuunyo kya ssaayansi w’ebintu. Embeera z’okuteekebwamu ion zirina obulabe obw’obukambwe: zigatta ebbugumu eryokya, kemiko ezivunda okuva mu ggaasi nga BF3 oba PH3, n’okukuba obutundutundu buli kiseera. Filamenti, etera okukola nga katodi, erina okubuguma okutuuka ku incandescence okufulumya obusannyalazo obwetaagisa okukuma omuliro n’okuyimirizaawo pulasima. Okulemererwa wano kivaako obutabeera mu ntebenkevu bwa bikondo, obucaafu bw’ebyuma, n’okuyimirira kw’okufulumya okusaasaanya ssente ennyingi.
Lwaki tungsten y’efuga ekifo kino? Eky’okuddamu kiri mu bintu byayo ebitaliiko kye bifaanana:
Okuziyiza ebbugumu erisukkiridde: Olw’okusaanuuka okusinga ebyuma byonna (3422℃), ekiwujjo kya tungsten kikuuma obulungi bw’enzimba ng’ebirala byandiremye.
Superior Sputter Resistance: Eziyiza okukulugguka okuva mu bbomu za plasma, okukakasa nti ewangaala nnyo n’ebitangaala bya ion ebirongoofu.
Okufulumya obusannyalazo okulungi ennyo: Eby’obugagga byayo eby’ebbugumu birungi nnyo okukola okutambula kw’obusannyalazo okutambula obutakyukakyuka okwetaagisa okukola pulasima okutebenkedde naddala mu nsibuko za Indirectly Heated Cathode (IHC).
Ebyetaago bya chips ez’omulembe oguddako-, omuli n’ezo ez’ebyuma ebikozesa amaanyi ga silicon carbide (SiC) ne gallium nitride (GaN), byongera okusitula tekinologiya ow’okusimba. Kino kivuga obwetaavu bw'ebitundu by'ensibuko ebyesigika n'okusingawo, eby'omutindo ogwa waggulu-. Omusulo gwa tungsten gukyuse okuva ku waya ennyangu okutuuka ku precision-engineered consumable, nga enkulaakulana mu kufuga ensengekera y’empeke n’okussaamu eddagala (okugeza, ne rare-earth oxides) eyongera ku buwangaazi bwayo n’obulungi bw’okufulumya.
Okunoonya ebitundu bino ebikulu eby’omulimu-kyetaagisa omukwanaganya alina obukugu obw’amaanyi mu byuma n’okwewaayo okukola obulungi. Okumala emyaka egisukka mu makumi abiri, Zhuzhou Kingdon Industrial & Commercial Co., Ltd (W/Mo Okuva mu 2004) ebadde linnya eryesigika mu byuma eby’omulembe ebiziyiza omuliro. Nga bakuguse mu biva mu tungsten ne molybdenum, Kingdon egaba obulongoofu obwa waggulu-ebintu ebikolebwa buli kiseera ebyetaagisa mu nkola ezisaba nga okuteekebwamu ion.
Ku bayinginiya n’abakugu mu kugula ebintu abanoonya ebitundu ebyesigika eby’ensibuko ya ion, omuli ‘high-performance tungsten filaments, Zhuzhou Kingdon egaba obukugu obukakasibwa n’okukola obulungi.
