South Asia lub semiconductor scene nyuam qhuav tau txais kev ntseeg siab: ob ntsug wafer tshuab ziab khaub ncaws, peb cov qauv tsim ua rau qhov tseeb, tam sim no ua haujlwm tag nrho ntawm lub chaw ntim khoom hauv Ho Chi Minh City, Nyab Laj. Cov no tsis yog "lwm yam khoom siv"- lawv twb tau hloov kho li cas cov neeg siv khoom siv lawv cov 8-nti wafer backend kab, txiav tawm lub sijhawm poob thiab nce cov naj npawb ntawm cov chips siv tau. Raws nraim qhov cuam tshuam peb tsom rau.
Tus neeg siv khoom tshwj xeeb hauv tsheb thiab cov neeg siv khoom ntim ntim khoom ntim - qhov chaw uas ib qho me me lossis qhov seem seem tuaj yeem tso rau tag nrho cov khoom. Ua ntej koom tes nrog peb, lawv cov kev ua haujlwm yog lub hauv paus caj dab: cais kev ntxuav thiab ziab tshuab txhais tau hais tias kev tuav cov wafer tas li, thiab tsis sib haum rau ziab cov khoom seem uas cuam tshuam cov txheej txheem photoresist. Lawv cov txiaj ntsig hovered ntawm 92% rau lub hlis, thiab lawv cov neeg siv kev lag luam tsheb tau loj hlob nyob tsis tswm. Lawv tau sim peb lwm lub tshuab ziab khaub ncaws, tab sis ib zaug lawv pom peb cov qauv ntsug ob chav chav thiab tag nrho -hauv- ib qho qauv? Qhov kev txiav txim tau meej.
Dab tsi ua rau lub tshuab ziab khaub ncaws ua si - hloov pauv? Cia peb pib nrog ob chav ywj pheej- sab saud thiab qis, txhua qhov tswj tau ntawm nws tus kheej. Qhov ntawd txhais tau hais tias lawv tuaj yeem khiav SPM acid ntxuav kom qhuav hauv ib qho thiab photoresist tshem tawm kom qhuav rau lwm qhov, tsis muaj tus ntoo khaub lig- paug, tsis tos. Tom qab ntawd muaj tag nrho -hauv- ib qho qauv tsim: ntxuav thiab qhuav hauv ib chav tsev, yog li wafers yeej tsis tawm hauv qhov chaw tswj hwm - loj heev rau txo kev puas tsuaj thiab khaws cov khoom seem. Lub pob zeb nitrogen sealing ua kom cov kab noj hniav sib cais nruj, thiab qhov siab -voltage electrostatic tshem tawm? Zaps zoo li qub uas yuav nyiam cov khib nyiab me me, ua kom qhov chaw nruab nrab. Ntawm specs? Nws hits<0.3μm particles per wafer (under 30 grains), runs at 100-2500 RPM (they've been using 1200 for their 8-inch wafers), and the UPTIME is over 95%-so it rarely skips a beat.

"Peb tsis ntseeg tias ib lub tshuab tuaj yeem kho ob peb qhov mob taub hau loj tshaj plaws -kom txog thaum peb qhib lub tshuab ziab khaub ncaws," tus neeg siv khoom tus thawj coj tau hais thaum lub sijhawm lees txais zaum kawg. "Hauv ib lub lis piam, cov txiaj ntsig tau nce los ntawm 92% mus rau 95.1%-uas yog ntau txhiab tus chips zoo hauv ib hnub. Ob chav cia peb khiav ob txheej txheem ib zaug, yog li peb cov kab dhau los nce 40%. rau peb ntxiv hauv Q1 2026 rau peb qhov tshiab 12-nti kab-lub tshuab ziab khaub ncaws no dhau los ua lub hauv paus. "
Qhov kev xa khoom no tsis yog kev muag khoom xwb- nws yog qhov pov thawj peb cov Semicilean series haum rau cov neeg Esxias sab hnub tuaj booming semiconductor xav tau. Peb tsis nres ntawm cov tshuab xa khoom, xws li: peb lub chaw haujlwm Hanoi, tau qhib ua ntej xyoo no, muaj cov engineers hauv zos hu 24/7. Yog tias lawv xav tau qhov parameter tweak lossis kev saib xyuas ceev, kev pab tsis nyob deb. Thiab lub tshuab ziab khaub ncaws kuaj xyuas tag nrho cov cheeb tsam lub thawv: haum KM-40N thiab A182-60MB cassettes (feem ntau ntawm no), khiav ntawm cov qauv deionized dej thiab cov khoom siv nitrogen, thiab nws qhov loj me (490mm dav, 1880mm siab) slots txoj cai rau hauv cov plag tsev nruj. Tsis muaj nqi reconfigurations, tsuas yog instant nqi.
Nyab Laj, Malaysia, Thaib teb - cov nroj tsuag semiconductor thoob plaws cheeb tsam tab tom loj hlob sai, thiab lawv xav tau cov cuab yeej ua haujlwm hnyav li lawv ua. Peb qhov kev txav mus tom ntej? Tweaking Semiclean series los tswj kub ntau dua -sensitive wafers, zoo li gallium arsenide, uas yog loj hauv micro-sensors. Thaum kawg ntawm hnub, nws tsis yog hais txog kev tsim cov cuab yeej "zoo meej"- nws yog hais txog kev tsim cov cuab yeej uas daws qhov teeb meem tiag tiag, ntxhov siab peb cov neeg siv khoom ntsib txhua qhov kev hloov pauv.
