Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the semiconductor device type?Insulated-gate field-effect transistor (IGFET)
2. What is the key performance metric?High input impedance and low static power consumption, facilitating energy-efficient electronic designs
3. What is a MOSFET and why is it called a tiny switch?A MOSFET is a small device that controls electricity like a gatekeeper. It lets current flow when a voltage is applied to its gate, acting like a tiny switch.
4. How does a MOSFET let electricity flow or stop?When a positive voltage is applied to the gate, electrons form a layer that connects the source and drain, allowing current. A negative voltage removes those electrons, increasing resistance and stopping current.

Dielectric Layer: An electrically insulating material, typically silicon dioxide, separating the gate from the semiconductor channel.
Enhancement Mode: A MOSFET configuration that is normally non-conductive and requires a gate voltage to create a conducting channel.
Complementary Metal-Oxide-Semiconductor (CMOS): A technology using pairs of complementary (n-type and p-type) MOSFETs for low-power digital logic circuits.
