**Questions about Field Effect Transistors:**

**Question 1:** How do etching stop structures improve the performance of field effect transistors?

**Answer:** Etching stop structures help control the etching process during manufacturing, ensuring precise alignment and reducing defects in the transistor, leading to improved performance and reliability.

**Question 2:** What are the main differences between the first and second etching stop structures in the field effect transistor?

**Answer:** The first etching stop structure separates the cap layer from the recess region near the source electrode, while the second etching stop structure separates the cap layer from the recess region near the drain electrode, providing distinct boundaries for etching control.


==Original Abstract Submitted==

A field effect transistor includes a first etching stop structure and a second etching stop structure. The first etching stop structure is formed on a first side surface of a recess region that is a boundary between a cap layer on a side of a source electrode and the recess region. The second etching stop structure is formed on a second side surface of the recess region that is a boundary between the cap layer on a side of a drain electrode and the recess region.
