Siab -Kev Ua Haujlwm Square Silicon Wafer Rau Circuit Fabrication

Technical Whitepaper: Siab -Kev Ua Haujlwm Square Silicon Wafer rau Kev Tshaj Tawm Tshaj Tawm

Cov Khoom Siv Science ntawm Carrier Mobility & Scattering Suppression

Hauv kev tsim cov khoom siv siab -kev ua haujlwm sib xyaw ua ke (ICs), lub substrate lub atomic qauv ncaj qha cuam tshuam qhov ceev ntawm electron thauj. PebSiab -Kev Ua Haujlwm Square Silicon Waferyog engineered kom tsawgLattice-Level Phonon Scattering. Los ntawm kev siv ib qho ultra- ntshiab monocrystalline silicon ($ 11\\text{N}$ purity) thiab ib tug proprietary low-kev loj hlob raws tu qauv, peb xyuas kom meej ib tug pristine crystalline ib puag ncig. Qhov no txo ​​cov naj npawb ntawm cov chaw tawg ntawm cov silicon -dielectric interface, ua kom pom tseebCarrier Mobility ($\\mu$). Rau siab heev CMOS thiab analog circuits, qhov no txhais mus rau hauv kev hloov ceev ceev, txo hwj chim noj, thiab ib tug txhim khu kev qha Signal - mus rau -Noise Ratio (SNR).

Engineering ntawm Circuit Fabrication Base

Exceptional Surface Planarity rau Lithographic Fidelity:High- circuits ceev yuav tsum tau ceev heev nyob rau hauv photolithography. Peb wafers feature aTag nrho Thickness Variation (TTV) ntawm <0.5umhla tag nrho cov square nto. Qhov kev lag luam no- ua kom tiaj tus ua kom ntseeg tau tias tag nrho cov reticle teb tseem nyob hauv qhov nqaimQhov tob- ntawm -Focus (DOF)ntawm siab -kev daws teeb meem steppers, tiv thaiv cov qauv distortion thiab ua kom lub rooj vag zoo ib yam -length tswj rau sub-micron transistors.

Optimized Geometric Flux rau qhov siab kawg tuag tawm:Lub precision square geometry yog qhov kev xaiv tsim qauv zoo rauLoj -Scale Circuit layouts. Los ntawm kev muab ib qho $90^\\circ$ hneev taw, lub wafer tshem tawm "Edge-Exclusion" zones pom nyob rau hauv ib txwm ncig substrates. Rau cov chaw tsim khoom ntawm complex ICs thiab multi-chip modules (MCMs), qhov square layout nce qhovzoo tuag- tawm los ntawm 18-22%, ua kom cov khoom siv tau zoo thiab txo tus nqi -ib -wafer.

Superior Thermal Dissipation rau siab -Kev sib xyaw ua ke:Qhov no yog qhov tseem ceeb rau kev ua haujlwm siab -cov txheej txheem kev ua haujlwm thiab kev tswj hwm lub zog ICs, qhov uas tshem tawm cov cua sov sai ntawm cov kev sib txuas ua haujlwm tiv thaiv "Thermal Throttling" thiab ua kom ntev - lub sij hawm cov cuab yeej kev ntseeg siab nyob rau hauv tas li load.

Kev ua tau zoo ntawm hluav taws xob zoo rau siab -Yield Production:Peb cov wafers tau dhau los ua qhov nruj radial resistivity variation (RRV) tswj txheej txheem. Qhov no tau lees paub tias cov cuab yeej tsim tawm ntawm cov ces kaum ntawm lub xwmfab nthuav tawm cov yam ntxwv hluav taws xob zoo ib yam rau cov neeg nyob hauv nruab nrab, ua kom lub sijhawm zoo ib yam thiab qhov hluav taws xob ntau dhau ntawm cov txheej txheem nyuaj- ntawm -Chip (SoC) tsim.

Kev siv tswv yim

Advanced IC Fabrication:Lub substrate hwm zoo rau microprocessors, nco arrays, thiab cov teeb liab digital processors (DSPs) xav tau siab crystalline purity.

Analog & Mixed -Signal Circuits:Qhov zoo tshaj plaws qis - suab nrov platform rau siab - cov hloov pauv qhov tseeb thiab RF pem hauv ntej - kawg modules.

Advanced Ntim & MCMs:Qhov ruaj khov, siab -flatness puag rau ntau-chip modules qhov twg square die layouts yooj yim inter{2}}chip routing.

MEMS & Integrated Sensor Systems:Txhawb kev tsim khoom ntawm siab -kev ua tau zoo accelerometers thiab siab sensors nrog superior mechanical stability.
