Maƙasudin ƙimar zafi na dangi a cikin ɗaki mai tsabta na semiconductor (FAB).

Maƙasudin ƙimar zafi na dangi a cikin ɗaki mai tsabta (FAB) yana kusan 30 zuwa 50%, yana ba da damar kunkuntar gefen kuskure na ± 1%, kamar a cikin yankin lithography - ko ma ƙasa da haka a cikin sarrafa ultraviolet mai nisa (DUV) zone - yayin da sauran wurare ana iya shakatawa zuwa ± 5%.
Saboda yanayin zafi na dangi yana da kewayon abubuwan da za su iya rage ayyukan ɗakuna masu tsafta, gami da:
1. Ci gaban kwayoyin cuta;
2. Yanayin zafin jiki na dakin dakin ga ma'aikata;
3. Electrostatic cajin ya bayyana;
4. Karfe lalata;
5. Ruwa tururi condensation;
6. Lalacewar lithography;
7. Ruwan sha.

Bacteria da sauran gurɓataccen yanayi (molds, ƙwayoyin cuta, fungi, mites) na iya bunƙasa a cikin mahalli tare da yanayin zafi fiye da 60%. Wasu al'ummomin ƙwayoyin cuta na iya girma a yanayin zafi fiye da 30%. Kamfanin ya yi imanin cewa ya kamata a sarrafa zafi a cikin kewayon 40% zuwa 60%, wanda zai iya rage tasirin ƙwayoyin cuta da cututtukan numfashi.

Dangantakar zafi a cikin kewayon 40% zuwa 60% shima matsakaicin kewayo ne don jin daɗin ɗan adam. Yawan zafi zai iya sa mutane su ji cushe, yayin da zafi da ke ƙasa da kashi 30% na iya sa mutane su ji bushewa, faɗuwar fata, rashin jin daɗin numfashi da kuma rashin jin daɗi.

Babban zafi a zahiri yana rage tarin cajin lantarki akan farfajiyar ɗakin tsabta - sakamakon da ake so. Ƙananan zafi yana da kyau don tara caji da yuwuwar lalata tushen fitarwa na lantarki. Lokacin da yanayin zafi ya wuce kashi 50%, cajin wutar lantarki ya fara raguwa da sauri, amma lokacin da yanayin zafi bai wuce 30% ba, za su iya dawwama na dogon lokaci akan insulator ko ƙasa mara ƙasa.

Za'a iya amfani da zafi na dangi tsakanin 35% da 40% azaman sulhu mai gamsarwa, kuma ɗakuna masu tsabta na semiconductor gabaɗaya suna amfani da ƙarin sarrafawa don iyakance tarin cajin lantarki.

Gudun yawancin halayen sinadarai, gami da hanyoyin lalata, za su ƙaru tare da haɓakar yanayin zafi. Duk abubuwan da aka fallasa zuwa iska a kusa da ɗakin tsabta suna da sauri.
