Gukoresha doping bihindura mu buryo butaziguye ubwinshi bw'umuvuduko wa germanium, ubushobozi bwo guhangana n'ingufu, n'ubushobozi bwo kugabanya ingano y'amashanyarazi ya germanium. Kugenzura ingano ya fosifore, antimoni, arsenic, na boron mu buryo bwa semiconductor bigomba kugera kuri sub-ppm ku bikoresho by'ikoranabuhanga na photonic bikora. Guhindura neza ingano ya fosifore cyangwa antimoni bigabanya ubucucike bw'imigozi muri Ge-on-Si, bikongera uburyo bwo kugenda no gutanga umusaruro ku byuma bipima na transistors. Dopositi ikabije—nk'iyo hejuru ya 2×10¹⁹ cm⁻³ yttrium—bigabanya ubwizigirwa binyuze mu kongera ubucucike bw'imitego, bigaragaza ko ari ngombwa gusesengura ibintu biri ahantu runaka.

Imbogamizi z'uburyo busanzwe bwo gusesengura ibintu by'ibanze
Uburyo gakondo bushingiye ku gupima ibintu byangiza kandi bisaba gutegura imiti ikoreshwa mu buryo bwa "wet chemistry" cyangwa "ion probe" mu ntambwe nyinshi. Ingendo zo gusesengura akenshi zirenga amasaha 6 kuri buri cyiciro, bigabanyiriza uburyo bwo kugenzura ibikorwa mu buryo bwihuse. Iyi mikorere ntishobora gushyigikira tekiniki zo gusesengura ibintu mu buryo bwihuse cyangwa gupima imiterere y'ibinyabutabire mu buryo bwihuse kugira ngo hakorwe umusaruro mwinshi cyangwa gucunga umusaruro mu rugero rwa "wafer". Kubera ko utudomo tw'ibikoresho tugenda dugabanuka, icyifuzo cya spectrometer za XRF zikoreshwa mu ntoki n'ibikoresho byo gusesengura bya XRF bitwarwa mu ntoki kugira ngo hakoreshwe ibizamini byihuse kandi bitangiza ibyuma bipima ibintu mu buryo bwihuse byihuta cyane. Ibikoresho byo mu buryo butaziguye gusa, bikoresha ikoranabuhanga rigendanwa, ni byo bihita bitanga serivisi.semiconductorisesengura ry'ibikoresho, riziba icyuho kiri hagati yo guhuza ibikorwa n'uburyo bwo gukurikirana ibintu mu buryo bw'ikoranabuhanga.
Ikoranabuhanga rya XRF Spectrometer rikoreshwa mu buryo bw'intoki: Guhindura Isesengura ry'Ibintu Bisanzwe mu Buntu
Amahame ya X-ray Fluorescence (XRF) mu Gupima Ibintu by'Ibintu
Irangi rya X-ray (XRF) rikora binyuze mu gukurura atome z'icyitegererezo hakoreshejwe imirasire ya X y'ibanze, bigatera isohoka rya X-rays y'urumuri yihariye. Isesengura ry'ibintu byinshi muri semiconductor za germanium rigizwe n'intambwe eshatu: gukurura, gusohora, no kumenya. Iki gikoresho gipima fotoni z'urumuri, kikabyara spectrum aho buri gasongero gahuye n'ikintu runaka. Imipaka yo kumenya sub-ppm itanga ibipimo byizewe ku bintu by'ingenzi biri mu bice bikomeye, harimo fosifore, boron, arsenic, na antimoni - ingenzi cyane ku ikoreshwa rya semiconductor za germanium. XRF ikora isuzuma ridasenya nta gutegura icyitegererezo, ikemura ibibazo byihuse kandi mu gihe nyacyo byo gupima imiterere y'ibintu mu ikorwa rya semiconductor.
Ibintu by'ingenzi biranga imashini zigezweho zo gusesengura XRF
Spektrometero za XRF zikoreshwa mu ntoki zifasha mu gupima vuba imiterere y’ibinyabutabire mu mabuye y’agaciro, ibyuma, n’ibikoresho bya semiconductor, bigatuma habaho uburyo bwo gusesengura ibintu bya germanium na silicon semiconductors. Gupfuka neza no kurinda ivumbi bituma bikoreshwa mu bintu bigoye, harimo n’ibyumba byo gusukura no kugenzura imirima.
Udukoresho twa silicon dupima neza cyane dutanga isesengura ry’ibikoresho bya semiconductor mu rwego rwa laboratwari, tugatandukanya ibikoresho by’icyuma n’ibitari ibyuma mu buryo bunonosoye. Uburyo bwo guhuza insinga n’ibikoresho bikoresha bateri bworohereza isuzuma ridasenya rya semiconductor, bugabanya imbogamizi mu mikorere, kandi bugatuma igenzura rya wafer rirushaho kwihuta. Isesengura rya ecran n’imikorere ya batch reporting bitanga ubwiza bworoshye, bihura n’ibisabwa mu gupima imiterere y’ibikoresho bya semiconductor.
Ibikenewe by'ingenzi mu gusesengura imiti igabanya ubukana bw'ibiyobyabwenge ku bikoresho bya Germanium
Injeniyeri za semiconductor zisaba ko zizewe kandi zishobora gukurikiranwaisesengura ry'ibanzekuri buri cyiciro, kuva kuri germanium mbisi kugeza kuri wafers zarangiye. Gupima imiterere y'ibice by'ingenzi mu gihe nyacyo byemeza ko byujuje ibisabwa mu kwihanganira imiterere y'ibice by'ingenzi kandi bikarinda igihombo kirenze 5%. Imashini ipima XRF igendanwa yo gusesengura ibice by'ingenzi ituma habaho uburyo bwo gusesengura ibice by'ingenzi mu gihe cyabyo, bukenewe mu gupima ibice by'imiti mu gihe cyabyo haba mu gihe cyabyo, bigakuraho gutinda no kwangirika kw'ibicuruzwa.
Gukurikirana ibikorwa hakoreshejwe ikoranabuhanga rya XRF spectrometer rikoreshwa mu ntoki bigabanya igipimo cy’ikosa ry’ibikoresho binyuze mu kwemerera isuzuma ritaziguye, ritangiza ibyuma bya semiconductor mu buryo bwo mu murima no mu cyumba cyo gusukura. Gukurikirana mu buryo bwihuse bituma inkomoko y’ikosa ishobora gushyirwa ku bikoresho byihariye. Ugereranyije na silicon, ingufu nke za germanium zituma uburinganire bw’ibikoresho burushaho kuba ingenzi. Guhindagurika kwa boron cyangwa fosifore birenga 10% bifitanye isano itaziguye n’ihinduka ry’amashanyarazi hanze y’intego z’igishushanyo, bikongera igipimo cy’ikosa ry’ibikoresho.
Ibikorwa byo gukoresha ingufu nyinshi bisaba ibisubizo nka XRF ikoreshwa mu ntoki kugira ngo habeho isuzuma rya semiconductor ritanga igenzura ry’imikorere mu masegonda make, nta gutsemba ingero. Kwandika amakuru hamwe no gutanga raporo ku buryo butaziguye byihutisha inyandiko no kugabanya imbogamizi mu mikorere. Ibi bikoresho bigomba gutanga isesengura ryuzuye ry’ibikoresho bya semiconductor, gushyigikira igenzura ry’ibisobanuro no gukemura ibibazo byihuse muri porogaramu zose za semiconductor za germanium.
Lonnmeter XRF Analyser: Igisubizo cy’ingenzi cyo gusesengura Germanium Doping Analyser
Iyi mashini ipima ikirere ya silikoni, ifite imiyoboro myinshi ikura cyane, ituma habaho uburyo bwo gukora neza muri laboratwari ndetse no gukora neza cyane. Uburyo bwo gukora neza bwa semiconductor butuma ikoreshwa ako kanya—nta gahunda yo gukora neza isaba. Uburyo bwo gukora kuri ecran bworoshya isuzuma ry’imiti mu kigo. Ifite ubushobozi bworoshye bwo gukora, ikoresha bateri, ishyigikira isuzuma ritangiza imikorere rya semiconductor mu buryo bworoshye haba mu murima ndetse no mu cyumba cy’isuku.
Ingendo zisanzwe zo gupima zitanga ibisubizo byuzuye mu masegonda 30. Kubika amakuru mu buryo buhuriweho bitanga uburyo bwo gukurikirana amakuru mu buryo buhuriweho. Guhuza amakuru hakoreshejwe umugozi bitanga uburyo bwo gusangira ibisubizo ako kanya no kwandika inyandiko zigenzura ubuziranenge bwa kure. Isesengura rishyigikira kumenya alloy na raporo ikomeye y’ibarurishamibare kugira ngo harebwe iyubahirizwa ry’amabwiriza.
Inyungu ku mikorere ya semiconductors
Lonnmeter igabanya ihinduka ry'isesengura kuva ku minsi kugeza ku minota, ikuraho ibibazo byo muri laboratwari. Isesengura ryihuse ryemeza ko gukoresha doping ari byo mu buryo bwa germanium semiconductor, rituma habaho uburyo bwihuse bwo kugabanya ikibazo cy'ibikoresho no kongera gukora. Gutanga ibitekerezo kuri interineti bifasha injeniyeri gukemura ibibazo biri mu miterere y'ikoreshwa ry'imashini zikoresha doping mu gihe cyo gukora.
Uburyo bwo gusaba igiciro
Hamagara itsinda ry’abacuruzi rya Lonnmeter ukoresheje urubuga rwabo. Uzuza ifishi yo kubaza kuri interineti, ugaragaze ubwoko bw’ingero n’aho badashobora kubona. Inzobere mu bijyanye no gukoresha porogaramu zabo zitanga serivisi zo gupima no gutanga inama za tekiniki zishingiye ku porogaramu za semiconductor za germanium. Ibiciro birimo imiterere isanzwe n’amapaki aboneka yo gupima semiconductor.
Ibibazo Bikunze Kubazwa
Ni ibihe bintu icyuma gipima amashanyarazi cya XRF gishobora kubona muri semiconductor za germanium?
Spektrometero ya XRF ikoreshwa mu ntoki ishobora gupima fosforu §, antimoni (Sb), arsenic (As), na boron (B) mu buryo bwa germanium ikomeye. Izi dopants—zikubiyemo ibisabwa mu bwoko bwa n na p—zigaragaza ibipimo ngenderwaho biriho ubu mu mikoreshereze ya germanium semiconductor.
Ese spectrometero za XRF zikoreshwa mu ntoki zishobora gukoreshwa ku byuma bya semiconductor wafers?
Yego, Lonnmeter XRF yakozwe neza kugira ngo ikore isuzuma ridasenya ibikoresho bya semiconductor biri mu buryo bukomeye, harimo no gupima bitaziguye ku bipimo bya germanium wafers n'ibice byarangiye. Imikorere ya telefoni igendanwa ituma abahanga mu by'ikoranabuhanga bakora igenzura ryihuse mu buryo bwose bushoboka, bigakuraho gutinda kugaragara mu isuzuma rya laboratwari gusa.
