Dab tsi yog Dry Etching hauv Semiconductor Manufacturing?

Qhuav etchingyog cov txheej txheem tshem tawm cov khoom siv plasma lossis reactive gases rau etch nyias zaj duab xis nrog siab precision thiab anisotropy. Piv nrog ntub etching, qhuav etching muaj:

Zoo dua qhov ntsuas qhov ntsuas (CD) tswj

Txhim kho qauv fidelity

Compatibility nrog advanced node manufacturing

Cov txheej txheem qhuav etching muaj xws li:

Plasma etching

Reactive Ion Etching (RIE)

Inductively Coupled Plasma (ICP) etching

Fluorine-raws li cov pa roj xws li R32, SF₆, thiab C₄F₈ tau dav siv vim lawv cov tshuaj muaj zog muaj zog nrog silicon- cov khoom siv.

Etching Mechanism ntawm R32 hauv Plasma Txheej Txheem

Raws li plasma tej yam kev mob, R32 (CH₂F₂) dissociates los tsim active fluorine radicals (F·) thiab lwm hom reactive.

Key Etching Functions ntawm R32

Fluorine radicals hnov mob nrog silicon- muaj cov ntaub ntawv los ua cov khoom lag luam tsis zoo

Ua kom muaj txiaj ntsig zoo ntawm Si₃N₄ (silicon nitride)

Muab tswj etch tus nqi tsim nyog rau cov qauv zoo

Piv nrog rau ntau dua - fluorine gases, R32 tso cai rau kev tswj tau ntau dua etching tus cwj pwm, ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov uas qhov kev xaiv thiab kev tswj hwm qhov profile tseem ceeb.

Vim li cas R32 siv rau Si₃N₄ Qhuav Etching

R32 feem ntau xaiv rau Si₃N₄ plasma etching vim yog cov hauv qab no zoo:

1. Tswj Ech Rate

R32 provides a moderate fluorine density, allowing better control over etch speed and uniformity.

2. Cov txheej txheem zoo ruaj khov

Nws tus cwj pwm decomposition hauv plasma txhawb kev ruaj khov etching tej yam kev mob, tshwj xeeb tshaj yog ua ke nrog lwm cov txheej txheem gases.

3. Kev sib xyaw nrog cov roj sib xyaw

R32 feem ntau siv ua ke nrog lwm cov pa roj kom zoo -tune:

Etch selectivity

Sidewall profile

Nto roughness

4. Kev xav txog ib puag ncig

Nrog ODP=0 thiab GWP qis dua piv nrog qee cov roj fluorinated, R32 tau txais ntau dua hauv cov txheej txheem tsim khoom ib puag ncig.

Sib piv nrog lwm cov Etching Gases
