Ịghọta mkpa ndị na-ebu Epi dị na nrụpụta Semiconductor dị elu

N'ime ụlọ ọrụ semiconductor, mmepụta nke wafers epitaxial (epi) dị elu bụ nzọụkwụ dị oke mkpa n'ichepụta ngwaọrụ dịka transistor, diodes, na ihe ndị ọzọ eletrọnịkị. Isi ihe na usoro a bụihe ebu, ngwá ọrụ pụrụ iche emebere iji jide wafers nke ọma n'oge ntinye epitaxial. Mana kedu ihe bụ onye na-ebu epi, gịnị kpatara o ji dị oke mkpa maka nrụpụta semiconductor?

Uto Epitaxial: Isi Usoro na imepụta Semiconductor

Uto epitaxial, ma ọ bụ epitaxy, na-ezo aka usoro ịtụba obere oyi akwa nke ihe kristal n'elu wafer semiconductor. Igwe oyi akwa a, nke a maara dị ka oyi akwa epitaxial, nwere otu nghazi kristal dị ka ihe dị n'okpuru ebe a na-eji eme ka ihe ọkụ eletrik nke wafer dịkwuo elu. Epitaxy dị oké mkpa n'ịmepụta ngwaọrụ ndị na-arụ ọrụ dị elu nke chọrọ njikwa ziri ezi na nhazi na nhazi ihe.

Iji nweta àgwà a chọrọ na ịdị n'otu na oyi akwa epitaxial, a ghaghị ijide wafers na nkenke na nkwụsi ike n'oge usoro ntinye. Nke a bụ ebeihe ebuna-abata n'ime egwuregwu.

Ọrụ nke onye na-ebu Epi

An ihe ebubụ ihe a haziri ahazi nke na-ejide wafer n'oge usoro ntinye nke epitaxial. A na-emekarị ya site na ihe dị oke ọcha nke nwere ike iguzogide okpomọkụ dị elu na gburugburu ihe na-emeghachi omume na-etinye aka na epitaxy. Nhazi nke onye na-ebu ya na-eme ka o doo anya na a na-edobe wafers nke ọma ma kpughee ya na ihe nkwụnye ego, na-ebute akwa epitaxial otu n'ofe n'elu wafer dum.

Otu n'ime isi ọrụ nke onye na-ebu epi bụ idowe nkwụsi ike na nhazi nke wafer n'oge usoro ntinye ego. Ntugharị ọ bụla ma ọ bụ ngbanwe ọ bụla nwere ike iduga ntụpọ na oyi akwa epitaxial, nke nwere ike imetụta arụmọrụ nke ngwaọrụ semiconductor ikpeazụ. Onye na-ebu ụgbọ ahụ ga-egbochikwa mmetọ ma hụ na wafers na-anọpụ na irighiri ma ọ bụ adịghị ọcha n'oge nhazi.

Ihe kpatara ndị na-ebu Epi ji dị mkpa na nrụpụta Semiconductor

Ogo nke oyi akwa epitaxial na-emetụta arụmọrụ nke ngwaọrụ semiconductor ozugbo. Dị ka ndị dị otú a, ọrụ nke onye na-ebu epi dị oké mkpa iji nweta ụkpụrụ dị elu achọrọ na ụlọ ọrụ ahụ. Site n'inye ebe kwụsiri ike na nke a na-achịkwa maka nhazi wafer, onye na-ebu epi na-ahụ na a na-edobe oyi akwa epitaxial n'otu n'otu na enweghị ntụpọ.

Ndị na-ebu Epi dịkwa mkpa n'ịkwado scalability nke nrụpụta semiconductor. Ka geometries ngwaọrụ na-aga n'ihu na-ebelata ma ọchịchọ maka ịrụ ọrụ dị elu na-eto eto, mkpa maka usoro epitaxial ziri ezi na nke a pụrụ ịdabere na ya na-adịwanye njọ karị. Ndị na-ebu Epi dị elu na-enyere ndị na-emepụta ihe aka imezu ihe ndị a site n'ịkwalite nsonaazụ na-agbanwe agbanwe na nke a pụrụ imepụtaghachi, ọbụlagodi ka mmepụta na-ebuli elu.

Mmechi

Na nchịkọta, onye na-ebu epi bụ ngwá ọrụ dị mkpa na usoro mmepụta semiconductor, karịsịa na mmepụta nke epitaxial wafers. Ọrụ ya n'ịhụ nkwụsi ike wafer, nhazi, na njikwa mmetọ dị mkpa maka ịnweta akwa epitaxial dị elu achọrọ maka ngwaọrụ semiconductor dị elu. Ka ụlọ ọrụ ahụ na-aga n'ihu na-agbanye ókèala nke nkà na ụzụ, mkpa nke ndị na-ebu epi a pụrụ ịdabere na ya na-arụ ọrụ nke ọma ga-abawanye, na-eme ka ha bụrụ akụkụ dị mkpa na nchụso nke kachasị mma na mmepụta semiconductor.

Maka ndị nọ na ụlọ ọrụ semiconductor na-achọ ịkwalite usoro epitaxial ha, nghọta na itinye ego na ndị na-ebu epi dị elu bụ nzọụkwụ dị oke mkpa iji nweta nsonaazụ kacha mma na ịnọgide na-asọmpi n'ahịa.
