Study Notes
Purification of Crystals
- Purification methods in chemistry are numerous, but for wafers, primarily three methods are used
- Those methods are: Polishing, Etching, and Heating
Etching
- Etching involves the selective removal of material from a sample by chemical or physical means
- It's a "reverse growth" process where surfaces of lowest energy are the most stable
- Regions of lattice distortion tend to be more susceptible to removal
Human Development
- A child grows up to become an adult, implying a process of growth and change
- Every individual has the potential to become their best self, but it requires self-exploration and development
Personal Growth and Self-Actualization
- The future of individuals is not in their raw, undeveloped state, but in their fully developed and refined form
- A person's full potential is only realized when they become a "finished product", implying a sense of fulfillment and completion
- Growth and development are necessary to become all that one was created to be, implying a sense of purpose and destiny
