Ixabiso ekujoliswe kulo lokufuma okuhambelanayo kwigumbi elicocekileyo le-semiconductor (FAB).

Ixabiso ekujoliswe kulo lokufuma okunxulumeneyo kwigumbi elicocekileyo le-semiconductor (FAB) limalunga nama-30 ukuya kuma-50%, livumela umda omxinwa wempazamo ye-±1%, njengakwizowuni ye-lithography - okanye nangaphantsi kwi-processing ye-ultraviolet ekude (DUV) indawo – ngelixa kwenye indawo inokuphumla ibe ±5%.
Ngenxa yokuba ukufuma okuhambelanayo kunoluhlu lwezinto ezinokunciphisa ukusebenza ngokubanzi kwamagumbi acocekileyo, kuquka:
1. Ukukhula kweebhaktheriya;
2. Uluhlu lobushushu begumbi kubasebenzi;
3. Intlawulo ye-Electrostatic ibonakala;
4. Ukonakala kwesinyithi;
5. Ukujiya komphunga wamanzi;
6. Ukuthotywa kwelithography;
7. Ukufunxwa kwamanzi.

Iintsholongwane nezinye izingcolisi zebhayoloji (umngundo, iintsholongwane, umngundo, amangolwane) zinokukhula kakuhle kwindawo ezinobufuma obungaphezulu kwe-60%. Ezinye iindawo ezihlala iintsholongwane zinokukhula kwindawo yokufuma okungaphezulu kwama-30%. Inkampani ikholelwa ukuba umswakama kufuneka ulawulwe kwi-40% ukuya kwi-60%, enokunciphisa impembelelo yeebhaktheriya kunye nezifo zokuphefumula.

Ukufuma okuhambelanayo kuluhlu lwe-40% ukuya kwi-60% kwakhona uluhlu oluphakathi lokuthuthuzela komntu. Ukufuma okugqithisileyo kunokwenza abantu bazive bexinene, ngelixa ukufuma okungaphantsi kwe-30% kunokwenza abantu bazive bomile, ulusu olukrazukileyo, ukungaphefumli kakuhle kunye nokungonwabi ngokweemvakalelo.

Ukufuma okuphezulu ngokwenene kunciphisa ukuqokelelwa kweentlawulo ze-electrostatic kwindawo ecocekileyo yegumbi - umphumo ofunekayo. Ukufuma okuphantsi kulungele ukuqokelelwa kwentlawulo kunye nomthombo onokuba yingozi wokukhutshwa kwe-electrostatic. Xa ukufuma okunxulumeneyo kudlula i-50%, iintlawuliso ze-electrostatic ziqala ukutshabalalisa ngokukhawuleza, kodwa xa ukufuma okunxulumeneyo kungaphantsi kwama-30%, zinokuzingisa ixesha elide kwisigqubuthelo okanye kumphezulu ongenamhlaba.

Ukufuma okuyeleleneyo phakathi kwe-35% kunye ne-40% kunokusetyenziswa njengento eyanelisayo, kwaye amagumbi acocekileyo e-semiconductor asebenzisa iindlela zokulawula ezongezelelweyo ukunciphisa ukuqokelelwa kweentlawulo zombane.

Isantya seempendulo ezininzi zeekhemikhali, kubandakanywa neenkqubo zokubola, ziya kunyuka ngokunyuka kokufuma okuhambelanayo. Yonke imiphezulu evezwe emoyeni ejikeleze igumbi elicocekileyo iyakhawuleza.
