Muchiitiko chekugadzira Semiconductor wafer Wafer Midroces neyakafambira mberi matanho ekugadzira, anenge makumi mashanu akasiyana marudzi emagasi anodiwa. Magasi anowanzo kupatsanurwa kuita magasi mazhinji uyemagasi akakosha.

Kushandiswa kwemagasi mu microyeltuctors uye semiconondductor maindasitiri ekushandiswa kwemagasi agara akaita basa rakakosha muSemiconductor Maitiro, kunyanya maitiro eSemiconductor anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana. Kubva kuULLI, TFT-LCD kune iyo micro-Electromechancal (Mams) maindasitiri, Semiconductor maitiro anogadzira maitiro, kusanganisira kuomesa, oidhi

Semuenzaniso, vanhu vazhinji vanoziva kuti machipisi akagadzirwa nejecha, asi akatarisa zvinhu zvese zvinodiwa, zvakadai seMoto, kupukuta mvura, gasi rakanzi, Gasi rakakosha, etc. dzinokosha. Kudzokera -Kugumisa kurongedza zvakare kunodawo Substrates, kufambidzana, kutungamira mapuranga, zvinhu zvekugadzira, nezvimwe zvinhu zvakasiyana siyana. Magetsi Special Gasi mune yechipiri yakakura zvinhu mumicononductor yekugadzira mari mushure mekunge Silicon Wafers, inoteverwa nemasks uye mafoto.

Kuchena kwegesi kune simba rekusimbisa pane commence performance uye chigadzirwa goho, uye kuchengetedzwa kwegesi kunowanikwa kune hutano hwevashandi uye kuchengetedzeka kwefekitori. Nei kuchena kwegesi kuchikanganisa kukuru kuitwa mutsara uye vashandi? Izvi hazvisi zvekuwedzeredza, asi zvinotemerwa nehunhu hune ngozi hwegesi pacharo.

Kuiswa kwemagasi akajairika mune semiconductor indasitiri

Gasi rakajairika

Gasi rakajairika rinonzi zvakare Bulk gasi: Zvinoreva gasi rekushanda neyakagadzirirwa chinhu chakaderera kupfuura 5n uye kugadzirwa kukuru uye kutengesa vhoriyamu. Inogona kukamurwa kuita kuparadzaniswa kwemweya gasi uye synthetic gasi zvichienderana nenzira dzakasiyana dzekugadzirira nzira. Hydrogen (H2), Nitrogen (N2), oxygen (O2), Argon (A2), etc.;

Specialty gasi

Gasi rehunyanzvi rinoreva gasi rekushanda rinoshandiswa muminda yakatarwa uye ine zvakakosha zvinodiwa zvekuchena, dzakasiyana siyana, uye zvivakwa. KunyanyaSih4, Ph3, B2H6, A8H3,Chisni, Cf4,Nh3, Polc3, Sih2cl2, Sihc3,Nh3, BCL3, Sif4, CLF3, CO, C2F6, N2O, F2, HF, HF,SF6… zvichingoenda zvakadaro.

Mhando dzeMafuta

Mhando dzemagasi akakosha: Controsive, ane muchetura, unopisa, kuchema-kutsigira, inert, nezvimwe.
Inowanzoshandiswa semiconductor magasi anogadziriswa seinotevera:
(i) corrosiv / ine muchetura:Chisni, BF3, WF6, HBB, SiH2CL2, NH3, Ph3, CL2,BCL3...
(ii) inopisa: H2,Ch4,Sih4, Ph3, Ash3, Sih2cl2, B2H6, Ch2F2, Ch3f, Co ...

(iv) Inter: N2,CF4, C2F6,C4f8,SF6, CO2,Ne,Kr, Iye ...

Mukuita kwepiconductor chip kugadzira, anenge makumi mashanu akasiyana emagasi egasi (anonzi semagasi akasarudzika) anoshandiswa, kuiswa, jekiseni, maitiro, uye matanho ese, uye nhanho yakazara, uye nhanho yakazara, uye nhanho yakazara, uye nhanho yakazara, uye nhanho yakazara, uye nhanho dzakazara dzinopfuura mazana. Semuenzaniso, ph3 uye ash3 vanoshandiswa se phosphorus uye arsenic zvinyorwa muIion yekufungidzira CF4, BCCOGE GESS CF4, BCE

Kubva pane zviri pamusoro apa, tinogona kunzwisisa kuti magasi emakesi mazhinji anokuvadza kumuviri wemunhu. Kunyanya, mamwe magasi, akadai se Sih4, anozvishingisa. Chero bedzi ivo vachisvetuka, ivo vanozoita nechisimba neokisijeni mumhepo uye vatanga kupisa; uye asa3 ine chepfu zvakanyanya. Chero kurerutsa kushoma kunogona kukonzera kukuvadza kune hupenyu hwevanhu, saka zvinodiwa zvekuchengetedzeka kwegadziriro yekudzora system yekushandisa masheketi akanyanya.

Semiconductrsors inoda yakakwirira-yekuchena magasi kuti ive ne "madhigiri matatu"

Kuchena kwegesi

Zviri mukati meiyo yekusvibisa mamiriro mune gasi inowanzo kuratidzwa sepesenti yekuchena kwegesi, yakadai sa99.99999%. Kunyanya kutaura, kuchena kunodiwa kune magasi emagetsi anosvika 5n-6n, uye kunoratidzwa nehoriyamu yehurongwa hwekusvibisa PPM (PPB (chikamu pamabhiriyoni), uye PPT (chikamu pane trillion). Iyo yemagetsi semiconductor shamba ine zvakanakisa zvinodiwa zvekuchena uye kusimba kwemhando yemagasi akakosha, uye kuchena kwemagasi makuru emagetsi kazhinji kwakanyanya kupfuura 6n.

Kuoma

Zvemukati wemvura yekuteedzera mvura mugesi, kana kunyorova, inowanzoratidzwa muDow Point, yakadai seyemweya yeAtmospheric dow -70 ℃.

Kuchena

Nhamba yezvinyorwa zvakasvibisa mugesi, zvimedu zvine size yehukuru hwe μm, inoratidzwa mune mangani masvingo / m3. Yemhepo yakamanikidzwa, inowanzo kuratidzwa muMG / M3 ye isingadzivirirwe yakasara yakasara, iyo inosanganisira mafuta.
