n B Fill in the Blanks. Answ er all questions. (2 points each) 61: Integrated Circuits (Cs) are essentially miniaturized electrical us buit o 021 Wsubra At an atomic scale the silicon wafer has a 022 wB2 strudture. To enhance its electrical properton silion is -Q23 WB1with either boron or phosphorus. as Q24 WB2_is used to cover the wafer with a material. To remove Q25 WB2which was deposited on the wafer via spinning is e lithography machine. The wafer is then 027 Separating the cips from the wafer is called_28 WB1- During the fabrication of ICs a layering process such material from the wafer xposed to Q26 WB1_while in a 7_WB2 to preferentially remove material from the surface
