What are the main components that make up a photoresist? 2. What is a two-component resist? What are the two components? 3. What does the concept of dose involve? 4. What effect does the dose have on the molecular weight of a negativeresist? (Does it cause it to decrease or increase?) 5. Identify one problem that can arise when positive resist is applied to athermally grown oxide wafer (silicon substrate). How can this problembe resolved?

Consider four of semiconductor samples: solid A is orange, solid B is black, solid C is white, and solid D is yellow. Given their colors, rank these semiconductors in order of increasing band gap. A. B < A < D < c B. B < D < A < C C. C < D < A < B D. C < A < D < B

A. Why does the conductivity of a semiconductor and some insulators change with impurity content? Compare this with the behaviour of metallic conductors. B. Discuss the location of the Fermi levels of intrinsic and extrinsic (n-type and p-type) semiconductors in low temperature and high temperature ranges. C. Discuss why the structure of the p-n junction is so important to modern technologies that impact our daily life.

Explain, what is the potential barrier in semiconductors. Note: no need to give an exact definition, please explain it in an easy way.

Which statement(s) is (are) true about a P-N junction: A. P-N junction consists of n-type and p-type semiconductor materials.B. Free electrons in n-type diffuse across junction to p-type.C. A depletion region formation happens due to electrons and holes moving away from each other due to the electric field.

An intrinsic semiconductor has some holes in it at room temperature. What causes these holes?   Group of answer choices a.) Valence electrons b.) Thermal energy c.) Doping d.) Free electrons
