Zosankha Zogwiritsa Ntchito Doping:
1. Yosasinthidwa:Ma wafer awa alibe mankhwala oletsa kugwiritsa ntchito mankhwala osokoneza bongo ndipo amagwiritsidwa ntchito makamaka pa ntchito zapadera monga kukula kwa epitaxial, komwe wafer amagwira ntchito ngati gawo loyera.
2.N-Type (Te Doped):Kugwiritsa ntchito mankhwala osokoneza bongo kwa Tellurium (Te) kumagwiritsidwa ntchito popanga ma wafer amtundu wa N, zomwe zimapangitsa kuti ma elekitironi aziyenda bwino komanso kuti azigwiritsidwa ntchito pozindikira ma infrared, zamagetsi othamanga kwambiri, ndi zina zomwe zimafuna kuyenda bwino kwa ma elekitironi.
3. Mtundu wa P (Ge Doped):Kugwiritsa ntchito mankhwala osokoneza bongo a Germanium (Ge) kumagwiritsidwa ntchito popanga ma wafer amtundu wa P, zomwe zimapangitsa kuti pakhale kuyenda bwino kwa maenje akuluakulu komanso kupereka magwiridwe antchito abwino kwambiri a masensa a infrared ndi ma photodetector.

Zosankha za Kukula:
1. Ma wafer amapezeka mu mainchesi awiri ndi atatu. Izi zimatsimikizira kuti zimagwirizana ndi njira zosiyanasiyana zopangira ma semiconductor ndi zipangizo.
2. Wafa wa mainchesi awiri uli ndi mainchesi 50.8±0.3mm m'mimba mwake, pomwe wafa wa mainchesi atatu uli ndi mainchesi 76.2±0.3mm m'mimba mwake.

Kutsogolera:
1. Ma wafer amapezeka ndi ma direction a 100 ndi 111. Ma direction a 100 ndi abwino kwambiri pa zamagetsi ndi ma infrared detectors othamanga kwambiri, pomwe ma direction a 111 amagwiritsidwa ntchito nthawi zambiri pazida zomwe zimafuna mphamvu zamagetsi kapena kuwala.

Ubwino Wapamwamba:
1. Ma wafer awa amabwera ndi malo opukutidwa/odulidwa bwino kuti akhale abwino kwambiri, zomwe zimathandiza kuti ntchito ikhale yabwino kwambiri pa ntchito zomwe zimafuna mawonekedwe enieni a kuwala kapena magetsi.
2. Kukonzekera pamwamba kumatsimikizira kuti pali chilema chochepa, zomwe zimapangitsa kuti ma wafer awa akhale abwino kwambiri pozindikira ma infrared komwe magwiridwe antchito ndi ofunikira kwambiri.

Yokonzeka Kuphika:
1. Ma wafer awa ndi okonzeka kugwiritsidwa ntchito, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito popangira epitaxial kukula komwe zigawo zina za zinthu zidzayikidwa pa wafer kuti apange zida zapamwamba za semiconductor kapena optoelectronic.

Mapulogalamu

1. Zowunikira za infrared:Ma wafer a InSb amagwiritsidwa ntchito kwambiri popanga zida zowunikira ma infrared, makamaka m'magulu a infrared a mid-wavelength (MWIR). Ndi ofunikira kwambiri pamakina owonera usiku, kujambula kutentha, komanso kugwiritsa ntchito zida zankhondo.
2. Machitidwe Ojambulira a Infrared:Kuzindikira kwambiri kwa ma wafer a InSb kumalola kujambula zithunzi zenizeni za infrared m'magawo osiyanasiyana, kuphatikizapo chitetezo, kuyang'anira, ndi kafukufuku wasayansi.
3. Zamagetsi Zachangu Kwambiri:Chifukwa cha kuyenda kwawo kwa ma elekitironi ambiri, ma wafer awa amagwiritsidwa ntchito mu zipangizo zamakono zamagetsi monga ma transistors othamanga kwambiri ndi zipangizo zamagetsi.
4. Zipangizo za Chitsime cha Quantum:Ma wafer a InSb ndi abwino kwambiri pogwiritsira ntchito zitsime za quantum mu ma laser, ma detector, ndi machitidwe ena a optoelectronic.
