Explain what a high density IC is, and give two advantages and two disadvantages of it.

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?

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