2/5 ICs are so cheap because of simultaneous production of hundreds of similar circuits on a small semiconductor wafer. 3. Explain why do ICs need small power for their operation? ICs need small power due to their small size. 4. Explain why are ICs more reliable than discrete circuits? ICs are more reliable because of elimination of soldered joints and need for fewer interconnections. 5. Explain what are the advantages of ICs over discrete component circuits? The advantages of IC’s over discrete component circuits are extremely small size, very small weight, very low cost, lower power consumption, more reliability, easy replacement, increased operating speed, close matching, improved functional performance, suitability for small signal operation etc. 6. Explain what are the important IC technologies used? IC technologies used are monolithic, thin­ and thick­flim , and hybrid or multichip. 7. Explain what is monolithic IC? A monolithic IC is one in which all circuit components and their interconnections are formed on a single thin wafer, called the substrate. 8. Explain why is SIO2 layer formed over the entire surface in a monolithic IC?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
