Semiconductor Quartz: Chinhu Chinokosha Mumazuva Ano Emagetsi
Nhanganyaya yeQuartz Materials
Quartz (SiO₂) inogona kufanana negirazi pakutanga kutarisa, asi yakasarudzika zvimiro zvinoiisa parutivi. Kusiyana negirazi rakajairwa, iro rine zvinhu zvakawanda (zvakadai sejecha requartz, borax, barium carbonate, limestone, feldspar, uye soda), quartz inoumbwa chete neSiO₂. Izvi zvinopa iyo yakapusa network dhizaini inoumbwa ne tetrahedral zvikamu zvesilicon dioxide.
Iko Kukosha Kwepamusoro-Kuchena Quartz
Yakakwirira-kuchena quartz, inowanzonzi "korona chishongo" chegirazi zvinhu, inopa yakasarudzika zvivakwa nekuda kwekushomeka kwayo kwesimbi. Ichi chinhu chinoshamisa chakakosha muakasiyana semiconductor maitiro, achizvikudza mabhenefiti akadai se:
1. High Temperature Resistance: Nekupfava kunosvika 1730 ° C, quartz inogona kutsungirira kushandiswa kwenguva refu pa1150 ° C uye inobata kuputika kupfupi kusvika ku1450 ° C.
2. Chemical Corrosion Resistance: High-purity quartz inoratidzira reactivity shoma neakawanda acids (kunze kwehydrofluoric acid) uye inoratidza kugadzikana kwepamusoro pakurwisa kemikari, kuva 30 nguva yakawanda acid-resistant kupfuura ceramics uye 150 nguva yakawanda kupfuura simbi isina tsvina.
3. Thermal Stability: High-purity quartz ine yakanyanya kuderera kupisa kwekuwedzera coefficient, ichibvumira kutsungirira nekukurumidza kuchinja kwekushisa pasina kutsemuka.
4. Optical Clarity: Nyaya iyi inochengetedza transmittance yakakwira munzvimbo yakakura, ine chiedza chinooneka chinodarika 93% uye ultraviolet transmittance inosvika pamusoro pe80%.
5. Electrical Insulation: High-purity quartz inopa kusarudzika kwemagetsi kupikisa, zvichiita kuti ive insulator yakanakisa kunyangwe pakudziya kwakakwirira.
Zvishandiso muSemiconductor Indasitiri
Nekuda kweaya akatanhamara emuviri uye emakemikari zvivakwa, yakakwira-kuchena quartz inoshandiswa zvakanyanya mumagetsi emazuva ano, kufonerana, uye semiconductor indasitiri. Iko kukura kuri kudiwa kwesilicon wafers kwakawedzera zvakanyanya kudiwa kwezvinhu zvequartz, kunyanya mukugadzira chip.
Mashandisirwo Akakosha eQuartz muSemiconductor Manufacturing:
1. High-Temperature Devices:
·Quartz Furnace Tubes:Yakakosha pakuita senge diffusion, oxidation, uye annealing, machubhu aya anovimbisa kugadzikana kwepamusoro-tembiricha uye kushanda zvakanaka panguva yekugadzira semiconductor.
Mabhoti eQuartz:Inoshandiswa kutakura uye kugadzirisa silicon wafers, mabhoti equartz anofambisa kugadzirwa kwebatch mukuparadzira maitiro.
2. Low-Tembiricha Devices:
·Quartz Rings:Yakabatanidzwa kune etching maitiro, mhete dzequartz dzinodzivirira kusvibiswa uye ive nechokwadi chekugadzira chaiyo panguva yelithography uye maitiro.
·Quartz Yekuchenesa Mabhasikiti uye Matangi:Izvi zvikamu zvakakosha pakuchenesa silicon wafers. Ivo vanofanirwa kuramba asidhi uye alkali uku vachideredza nzvimbo yekusangana kuti vawedzere kuchenesa.
Mhedziso
Nepo zvinhu zvequartz zvingaite sezvidiki zvinodyiwa mukugadzira semiconductor, vanoita basa rakakosha mukuona kunaka uye kuvimbika kwemidziyo yesemiconductor. Sekureva kweTechcet, yakakwira-kuchena quartz girazi zvinhu zvinoverengera inosvika makumi mapfumbamwe muzana epagore kugadzirwa kwepasirese muindasitiri yeruzivo rwemagetsi.
PaSemicera, isu takatsaurirwa kusimudzira iyo semiconductor indasitiri nekupa yakakwirira-inoshanda quartz zvinhu. Sezvinongoita zvipikiri zvakakosha pakuumbwa kwechimiro, ndizvo zvakaitawo quartz yekugadzira semiconductor.
2. Yakaderera-Tembiricha Devices:
·Quartz Rings: Yakabatanidzwa kune etching process, zvindori zvequartz zvinodzivirira kusvibiswa uye ive nechokwadi chekugadzira chaiyo panguva yelithography uye patterning.
·Quartz Yekuchenesa Mabhasikiti uye Matangi: Izvi zvikamu zvakakosha pakuchenesa silicon wafers. Ivo vanofanirwa kuramba asidhi uye alkali uku vachideredza nzvimbo yekusangana kuti vawedzere kuchenesa.
