Cryogenic Etching Yana Ba da damar Sarrafa Kayan Aiki Daidaitacce kuma Mai Iko

Yayin da masana'antu masu ci gaba ke ci gaba da turawa zuwa ga daidaito mafi girma, ƙara tsaurara tsarin sarrafawa, da kuma faɗaɗa jituwa tsakanin kayan aiki, fasahar etching tana ci gaba da bunƙasa daidai gwargwado. Cryogenic Etching, ta hanyar daidaita yanayin zafi na ɗaki da substrate, yana ba da damar sarrafawa mai ɗorewa da maimaitawa koda a sikelin nanometer. Ya zama muhimmin tsari a cikin kera semiconductor, ƙera na'urorin photonic, samar da MEMS, da dandamalin bincike na kimiyya.

Menene Cryogenic Etching?
Cryogenic etching tsari ne na etching bisa plasma wanda ake yi a yanayin zafi mai ƙarancin yawa, yawanci yana farawa daga -80 °C zuwa -150 °C ko ƙasa da haka. A lokacin aikin, ana kiyaye substrate a yanayin zafi mai zurfi mai ƙarfi, wanda ke ba da damar samfuran amsawa su samar da Layer mai sarrafawa akan saman kayan. Wannan tsari yana inganta daidaiton etching da ikon sarrafa tsari sosai.

Manyan hanyoyin sun haɗa da:
* Sassaka layi mai ƙarfi: Ingantaccen sassaka bango yana samar da siffofi masu madaidaiciya da kuma a tsaye.
* Inganta daidaiton amsawa: Ƙananan zafin jiki suna rage canjin saurin amsawa, suna inganta daidaiton tsari.
* Ingancin saman da ya fi kyau: Rage tsatsauran saman yana tallafawa na'urorin lantarki masu aiki mai kyau da kuma masu saurin fahimta.

Babban Sassan Tsarin Etching Mai Tsabta
Tsarin etching na yau da kullun ya ƙunshi:
* Ɗakin Cryogenic da matakin lantarki mai sanyaya don aiki mai ƙarfi-ƙananan zafin jiki
* Tushen plasma (RF / ICP) don samar da nau'ikan amsawa masu yawa
* Tsarin kula da zafin jiki (kayan sanyaya) don kiyaye tagar tsari mai dorewa
* Tsarin isar da iskar gas, mai tallafawa iskar gas kamar SF₆ da O₂
* Tsarin kula da madauki mai rufewa wanda ke daidaita zafin jiki, matsin lamba, wutar lantarki, da kwararar iskar gas
Daga cikin waɗannan, aikin sarrafa zafin jiki shine babban abin da ke ƙayyade kwanciyar hankali na tsari na dogon lokaci da kuma sake maimaitawa.

Daidaiton Zafi a Tsarin Ƙirƙirar Ƙananan da Nano
A cikin ayyukan aiki na ƙananan da nano, ana amfani da tsarin etching na cryogenic tare da tsarin laser micromachining. Aikace-aikacen da aka saba amfani da su sun haɗa da gilashi ta hanyar tsari, ƙera na'urorin photonic, da alamar wafer.

Duk da cewa manufofinsu na zafi sun bambanta:
* Yin etching na cryogenic yana buƙatar kula da wafer ɗin a yanayin zafi mai zurfi mai ban tsoro
* Tsarin Laser yana buƙatar kiyaye tushen Laser a cikin taga mai kunkuntar, kusa da zafin ɗaki.
Duk hanyoyin biyu suna buƙatar daidaiton yanayin zafi na musamman.
Domin tabbatar da ingantaccen ƙarfin fitar da laser, ingancin hasken fitila, da kuma daidaiton sarrafawa na dogon lokaci, ana amfani da na'urorin sanyaya ruwa na laser masu inganci sosai. A aikace-aikacen laser mai sauri, ana buƙatar daidaiton sarrafa zafin jiki na ±0.1 °C ko mafi kyau (kamar ±0.08 °C).

A cikin yanayin masana'antu da bincike na gaske, na'urorin sanyaya sanyi masu yawan zafin jiki kamar na'urar sanyaya laser mai saurin gaske ta TEYU CWUP-20 PRO, tare da daidaiton zafin jiki na ±0.08 °C, suna ba da ingantaccen iko na zafi yayin aiki na dogon lokaci.

Aikace-aikace na yau da kullun
* Ana amfani da etching mai ban sha'awa sosai a cikin:
* Gilashin ion mai zurfi (DRIE)
* Ƙirƙirar tsarin guntu na photonic
* Kera na'urorin MEMS
* Sarrafa tashar microfluidic
* Tsarin gani mai daidaito
* Nano-fabrication akan dandamalin bincike
Duk waɗannan aikace-aikacen suna buƙatar cikakken iko akan tsaye na bangon gefe, santsi na saman, da kuma daidaiton tsari.

Kammalawa
Yin etching na cryogenic ba wai kawai rage zafin jiki ba ne. Yana nufin cimma yanayin zafi mai ɗorewa, mai cikakken iko wanda ke ba da damar daidaita daidaito da daidaito fiye da iyakokin hanyoyin etching na al'ada. Yayin da fasahar semiconductor, photonic, da nanomafacturing ke ci gaba da ci gaba, etching na cryogenic yana zama babban tsari mai mahimmanci, kuma ingantattun tsarin kula da zafin jiki sune tushen da ke ba shi damar yin aiki a duk ƙarfinsa.
