Solution: Yakagadziridzwa nzira dzekugadzira dzinowedzera hupenyu hwe crucible, ichidzikisa huwandu hwese hwekushandisa.

4. Nyaya: Custom Fit kune Specialized Furnaces

Solution: Semixlab inopa yakagadziridzwa crucible saizi, geometries, uye machira kuti aenderane akasiyana echoto zvinodiwa.

Iyo Yakakwirira Kuchena Quartz Crucible yekunyunguduka neSemixlab yakagadzirwa kuti isangane neyakaomarara zvinodiwa zvemazuva ano semiconductor uye photovoltaic kugadzirwa. Nekuchena kwepamusoro, kupikisa kwakanyanya kwemafuta, uye kuvimbika kwakaratidza, inogonesa kuita kwakagadzikana mukati mekunyungudika kwakakosha, kukura kwekristaro, uye maitiro ehuto hwehuni. Semugadziri anotungamira weChinese uye mutengesi wePamusoro Purity Quartz Crucible, Semixlab anotarisira nemoyo wese kuve mudiwa wako wenguva refu muChina.

Yakadzama Mashandisirwo ePamusoro Purity Quartz Crucible

1. Czochralski (CZ) Maitiro

Iyo Czochralski maitiro ndiyo yakasarudzika nzira yekugadzira monocrystalline silicon ingots, iyo inozocherwa kuita mawaferi emasekete akabatanidzwa uye zvishandiso zvemagetsi. Mukuita uku, polysilicon inoiswa mukati me quartz crucible uye yakanyungudutswa patembiricha iri pamusoro pe1,420 ° C.

Basa reQuartz Crucible:

● Inopa chigadziko chine chemikemikari chinoramba chichipisa zvakanyanya panguva yekunyungudika kunoramba kuchiita.

● Inochengetedza kusachena kwakaderera kupararira musilicon yakanyungudutswa, kudzivirira kusvibiswa kwedopant kusingadikanwi.

● Kujeka kwayo kwemaziso uye kugadzikana kwemaitiro kunogonesa kunyatsotarisa uye kudhonza kwekrisiti yakafanana.

● Inoderedza kusunungurwa kweokisijeni uye kugadzirwa kwebubble, zvose zvakakosha pakugadzira ingots dzisina kukanganisa.

Pasina yakakwira-kuchena quartz crucible, iyo CZ process ine njodzi yekugadzira wafers ane simbi kusvibiswa kana micro-defects, zvakananga kukanganisa semiconductor mudziyo kuita.

2. Doping uye Melting Maitiro

Doping ndiyo inodzorwa sumo yetsvina chaiyo musilicon yakanyungudutswa kuti igadzirise maitiro ayo emagetsi (n-mhando kana p-mhando), iyo inotsanangura mashandiro emidziyo yesemiconductor. Iyi nhanho inowanzoitika apo iyo silicon inonyungudutswa mu quartz crucible.

Basa reQuartz Crucible:

● Inoshanda semudziyo wakagadzikana unobvumira kuiswa kwedopant (semuenzaniso, boron, phosphorus, arsenic) pasina kupindirana kwemakemikari.

● Inochengetedza kufanana kwekupisa mukunyunguduka, izvo zvakakosha pakuwana chaiyo dopant concentration mhiri kwekristaro.

● Inodzivirira kusvibiswa kwakasiyana-siyana nekuda kwekuchena kwayo kwakanyanya, kuve nechokwadi chekuenderana kwemagetsi mumawafer.

● Inomira inodzokororwa kupisa uye kutonhora kutenderera panguva yakawanda doping inomhanya pasina deformation.

Nekugonesa yakachena uye yakagadzikana doping nharaunda, iyo quartz crucible inova nechokwadi chekuti semiconductor zvishandiso zvinosangana zvakaomesesa zvinodiwa zveresistivity uye mutakuri hupenyu hwese.

3. Oxidation & Diffusion Furnaces

Oxidation uye diffusion maitiro maviri epamusoro-tembiricha akaiswa kune silicon wafers kugadzira insulating layer (SiO₂) kana kuunza dopant maatomu. Aya matanho anoda setups yevira inochengetedza yakachena, yakagadzikana, uye inodzorwa mamiriro ekunze. Quartz crucibles yakakosha mune aya masisitimu.

Basa reQuartz Crucible:

● Inopa chengetedzo yewafers kana makemikari ari pasi pehutsinye hwebhasikoro anosvika 1,200°C.

● Inochengetedza makemikari akaperera mumhepo ine oxidizing kana dopant-rich atmosphere, kudzivirira kusvibiswa kwewafers.

● Inovimbisa kugadzikana kwemichina uye kuramba kune microcracking panguva yakareba yevira.

● Yayo yakatsetseka pamusoro pekupedzisira uye yakakwirira homogeneity inoderedza particle generation, yakakosha kune advanced semiconductor nodes.

Nekushandisa yakakwira-kuchena quartz crucibles mune oxidation uye diffusion mavira, vagadziri vanowana yepamusoro wafer pamusoro pemhando, yakaderedzwa density, uye yakakwirira mudziyo goho.
