U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Passage: Qalabka 'Complementary Metal Oxide Semiconductor' (CMOS) waa tiknoolajiyad lagu dhisayo wareegyada isku dhafan. Teknolojiyada CMOS waxaa loo isticmaalaa microprocessors, microcontrollers, RAM static, iyo circuits kale oo digital logic ah. Tiknoolajiyada CMOS waxaa sidoo kale loo isticmaalaa dhowr wareeg oo analog ah sida dareemayaasha sawirka ( dareemayaasha CMOS), beddelaha xogta, iyo gudbiyeyaasha aadka loo dhexgeliyo noocyo badan oo isgaarsiin ah. Frank Wanlass wuxuu soo saaray CMOS sanadkii 1963 isagoo ka tirsan Fairchild Semiconductor waxaana la siiyay US patent 3,356,858 sanadkii 1967. Patent-kan horumarineed, soo saarista aaladaha CMOS ayaa lagu qeexay, iyadoo lagu saleynayo oksaydhka kuleylka ee substrate silikoon si loo helo lakab silikoon dioxide ah oo ku yaal inta udhaxeysa xiriirinta qulqulka iyo xiriirka ilaha.  Su'aal: Shirkadee ayuu Frank Wanlass ka sameeyay CMOS?
