Khoom Description

Lub silicon carbide chuck (tseem hu ua SiC chuck, silicon carbide ceramic chuck, lossis porous ceramic nqus chuck) yog ib qho tseem ceeb hauv cov khoom siv lithography (xws li kauj ruam- thiab - scanners) siv los nqa thiab kho silicon wafers. Nws feem ntau yog tsim los ntawm siab - purity, siab - cov tshuaj tiv thaiv ntom ntom -bonded silicon carbide (RBSC) los yog tshuaj vapor deposited (CVD) silicon carbide ceramic khoom, featuring ib tug meej array ntawm lub tshuab nqus tsev qhov ntawm nws nto (tsis zoo li generic ripe engineered porous chuckc). Thaum lub sijhawm ua haujlwm, lub tshuab nqus tsev adsorption yog siv los ua kom ncaj thiab ruaj ntseg txuas lub wafer rau lub chuck qhov chaw, kom ntseeg tau tias lub wafer tswj qhov chaw siab heev thiab thermal stability thaum lub sij hawm lithographic raug. Cov tuam txhab tseem ceeb thiab cov chaw muag khoom silicon carbide rau cov ntawv thov siab - kawg suav nrog cov tuam txhab xws li Saint-Gobain, CoorsTek, Morgan Advanced Materials, thiab Kyocera Fine Ceramics.

Silicon Carbide Chucks for Lithography Equipment

Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm

Tshwj xeeb Thermal Stability: Silicon carbide cov khoom muaj cov thermal conductivity zoo heev (kwv yees li 100-200 W / m·K), ua kom cov cua sov sib npaug sai thiab txo cov thermal deformation ntawm lub wafer los ntawm lub zog raug. Nws tsis tshua muaj coefficient ntawm thermal expansion (kwv yees li 4.0 × 10⁻⁶ / K) yog nyob ze rau ntawm silicon nws tus kheej, kom ntseeg tau tias synchronized deformation nrog lub wafer nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias thiab tswj kev sib raug zoo. Cov khoom zoo tshaj ntawm silicon carbide yog qhov tseem ceeb.
Zoo Rigidity thiab Hardness: SiC ceramic muaj ib tug siab Young's modulus thiab siab hardness, guaranteeing tsawg deformation ntawm lub chuck lub cev nyob rau hauv lub tshuab nqus tsev adsorption rog thiab mechanical loads, yog li muab kev ruaj ntseg, ruaj khov. Qhov no ua rau sintered silicon carbide (SSIC) los yog recrystallized silicon carbide (RSIC) zoo tagnrho xaiv.
Superior Flatness thiab Surface Quality: Lub chuck qhov chaw ua haujlwm, feem ntau ua los ntawm alpha silicon carbide los yog CVD SiC rau purity siab tshaj, undergoes ultra{0}}precision polishing. Qhov no ua tiav lub ntiaj teb flatness feem ntau zoo dua 1 micrometer thiab hauv zos flatness ntawm nanoscale. Qhov tsis tshua muaj qhov roughness (Ra tuaj yeem ncav cuag qis dua 1 nanometer) txo qhov sib txawv ntawm kev sib cuag nrog lub wafer backside, txhim kho adsorption uniformity thiab kub dissipation efficiency.
Tshuaj lom neeg ruaj khov thiab huv si: Silicon carbide ceramic tiv taus cov kua qaub thiab alkali corrosion thiab tsis tshua muaj kev tsim cov kab mob. Nws cov khoom saum npoo tuaj yeem ua kom zoo dua los ntawm cov txheej txheej (piv txwv li, tshwj xeeb SiO₂ lossis CVD Sic txheej), ua tau raws li qhov yuav tsum tau ua rau ultra-kev huv huv ib puag ncig hauv kev tsim khoom semiconductor.
Low Outgassing thiab High Vacuum Integrity: Cov khoom siv ntom ntom nrog cov porosity tsawg heev (tsis zoo li cov khoom siv hluav taws xob ntxeem tau siv hauv cov ntxaij lim dej), ua rau muaj kev tawm tsawg tsawg hauv lub tshuab nqus tsev. Qhov no pab tswj kom ruaj khov adsorption quab yuam thiab kev ua haujlwm ntawm lub tshuab nqus tsev.

Core Applications

Silicon carbide chucks (los yog ceramic nqus chucks) feem ntau yog siv nyob rau hauv lub wafer theem ntawm advanced lithography tshuab. Lawv lub luag haujlwm tseem ceeb yog:

Precision Positioning thiab Fixation: Thaum lub sij hawm lithographic raug, lub wafer yog ruaj khov nyob rau hauv qhov chaw ntawm lub tshuab nqus tsev adsorption, tiv thaiv tej micromovement thiab xyuas kom meej positional raug (overlay raug) nyob rau hauv cov qauv hloov.
Thermal Management: Ceev ceev dissipates tshav kub generated ntawm lub wafer los ntawm qhov raug (tshwj xeeb tshaj yog nyob rau hauv DUV thiab EUV lithography), txo wafer thermal expansion thiab distortion. Qhov no yog qhov tseem ceeb rau kev tswj cov duab focal dav hlau thiab xyuas kom muaj qhov sib txawv ntawm qhov tseem ceeb.
Tswj Planarity: Muab lub ultra- tiaj tus, ruaj khov siv dav hlau rau wafer, them nyiaj rau me ntsis warpage ntawm wafer nws tus kheej. Qhov no ua kom tag nrho qhov chaw raug nyob rau hauv qhov pom qhov tob ntawm qhov ua kom pom tseeb ntawm lithography cov cuab yeej kho qhov muag.
Txheej Txheem Kev Sib Raug Zoo: Nws lub cev ruaj khov thiab tshuaj lom neeg tso cai rau nws tiv taus ib puag ncig cuam tshuam nrog cov txheej txheem lithography xws li ntxuav thiab ci.
