Ultra-pav ob- sab Polished Silicon Wafers

Technical Whitepaper: Ultra-Plat ob -Side Polished Wafers rau Advanced MEMS & Ntim

Cov Khoom Siv Kev Tshawb Fawb ntawm Geometric Symmetry & Sub{0}}Surface Integrity

Hauv siab -kev tsim khoom muaj tseeb, "Mechanical Silence" ntawm lub substrate yog qhov tseem ceeb. PebUltra-Plav Ob -Side Polished Silicon Wafersyog tsim los tshem tawm cov kev ntxhov siab asymmetric uas muaj nyob hauv ib qho - sab polished substrates. Los ntawm kev siv ib txhijDual -Side Chemical

Mechanical Planarization (CMP)txheej txheem, peb ua tau zoo kawg nkaus symmetrical lattice xeev. Qhov symmetry no tiv thaiv "Wafer Warpage" thaum lub sij hawm siab - kub thiab ua kom ntseeg tau tiasSub-Kev puas tsuaj saum npoo (SSD)raug txo kom tsawg tsawg ntawm ob lub ntsej muag. RauCompound Semiconductor BondingthiabSOI Manufacturing, qhov no muab ib qho pristine, siab -zog nto uas ua kom yooj yim rau atomic- theem fusion yam tsis muaj kev cuam tshuam ntawm txoj hlua khi.

Engineering the Nano-Scale Integration Platform

Tsis tshua muaj TTV rau Precise Lithographic Alignment:Siv lub xeev- ntawm-- kos duab sib tsoo thiab polishing tshuab, peb ua tiavTag nrho Thickness Variation (TTV) ntawm $< 1.0 \mu\text{m}$. Qhov no flatness heev yog qhov tseem ceeb rauPhotolithography, raws li nws ua kom ntseeg tau tias ob sab ntawm lub wafer nyob twj ywm hauv qhov tob tob - ntawm - tsom, ua kom muaj kev sib haum xeeb zoo nyob hauv ob -sab MEMS ua thiab ntau - txheejWafer-Level Ntim.

Daim iav-Level Surface Finish rau Optical & Nyias-Zoo Zoo Tshaj Plaws:Ob qhov chaw muaj qhov roughness ($R_a$) ntawm$< 0.05 \text{ nm}$. Qhov "ob npaug- Daim iav" qhov kawg no yog qhov zoo rauPrecision Optical Txheejthiab nyias- zaj duab xis tso tawm (PVD/CVD/ALD), qhov chaw tawg paj yuav tsum tau txo kom tsawg kom ntseeg tau tias kev ua haujlwm siab ntawm photonic waveguides thiab interferometric sensors.

Optimized rau Advanced MEMS Device Prototyping:Kev kho dual- polishing tso cai rau kev tsim cov txheej txheem ultra- nyias nyias thiab cov txheej txheem tshem tawm tsis yooj yim. Txij li ob sab yog qhov tsis xws luag-dawb, cov kws tshawb fawb tuaj yeem siv lub nraub qaum rau kev sib xyaw ua ke cua txias los yog cov ntsuas ntsuas theem nrab yam tsis muaj kev cuam tshuam cov qauv kev ncaj ncees ntawm thawj.MEMSntaus ntawv.

Txhim kho Compatibility nrog Wafer Bonding:Qhov tsis muaj backside roughness ua kom qhov siab tshaj qhov chaw sib cuag thaum lub sij hawmWafer Bonding(Anodic, Fusion, lossis Hybrid). Qhov no ua rau muaj kev txo qis hauv "Bonding Voids" thiab ua kom lub zog ntawm cov khoom sib txuas ua ke, uas yog qhov tseem ceeb rau 3D integrated circuits thiab heterogeneous integration.

Kev siv tswv yim

SOI (Silicon{0}}ntawm-Insulator) Kev tsim khoom:Cov txheej txheem pib cov khoom siv rau kev tsim cov qib siab - zoo SOI wafers ntawm ion- txiav lossis kev sib txuas.

Wafer-Level Packaging (WLP) & TSV:Txhawb kev sib koom ua ke ntawm Los ntawm-Silicon Vias (TSVs) thiab qib 3D stacking qhov twg ob npaug -sided flatness tsis yog- sib tham.

Compound Semiconductor & Heterogeneous Bonding:Qhov zoo tshaj plaws rau kev sib txuas Si nrog GaN, SiC, lossis InP rau siab - zaus thiab hluav taws xob hluav taws xob.

Advanced MEMS & Micro-Optics:Muaj ntau yam substrate rau fabricating micro{0}}lens, siab sensors, thiab ilv actuators.
