Inkomba ye-MOS: Amagilavu omsebenzi enziwe ngesikhumba senkomo esihle esinezicucu eziqinisayo esandleni nasezihlokweni zeminwe ukuze ahlale isikhathi eside emisebenzini enzima. Ingemuva elenziwe ngesikhumba esiqhekeziwe livumela umoya kodwa ligcine ukumelana nokugudleka. Ukusikwa kwesithupha kwe-keystone kuvumela isandla ukuba sinyakaze ngokwemvelo lapho sibamba amathuluzi, siphatha ukhuni, sisebenzisa imishini. Isibambo sesihlakala esinelastiki esigoqiwe sivimbela izinsalela ukungena futhi sigcina igilavu endaweni yayo. Ngemva kokuwagqoka isikhashana, isikhumba siyathamba futhi silandele isimo sesandla.
