Question
To increase their conductivity, impurities are added to these materials in doping. For 10 points each:
[10m] Name these materials that are categorized as either n-type or p-type based on their predominant presence of either electrons or electron holes.
ANSWER: semiconductors
[10h] This process is used to selectively remove material from a semiconductor substrate to create intricate patterns or structures. In this step of microfabrication, materials are removed from wafers.
ANSWER: etching
[10e] Because their resistance is nonlinear, semiconductors generally don't obey this law which states that current equals voltage times resistance.
ANSWER: Ohm’s Law
