SEMICONDUCTOR DEVICE AND METHOD OF FABRICATING A SEMICONDUCTOR DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17886433 titled 'SEMICONDUCTOR DEVICE AND METHOD OF FABRICATING A SEMICONDUCTOR DEVICE

Simplified Explanation

The semiconductor device described in the patent application includes a substrate, a fin structure on the substrate with a ridge portion and a bottom portion, a metal gate structure on the fin structure, and an epitaxy region connected to the fin structure.

  • The fin structure has a channel region and a fin region between the channel region and the bottom portion.
  • The critical dimension of the bottom portion increases towards the substrate to twice or more of the critical dimension of the channel region.
  • The metal gate structure extends in the cross-fin direction.
  • The epitaxy region is beside the metal gate structure in the lengthwise direction of the fin structure.
      1. Potential Applications
  • Advanced semiconductor devices
  • High-performance electronic devices
      1. Problems Solved
  • Improving device performance
  • Enhancing integration density
      1. Benefits
  • Increased speed and efficiency
  • Better control over device characteristics
  • Potential for smaller and more powerful electronic devices


Original Abstract Submitted

A semiconductor device and a method of fabricating a semiconductor device are provided herein. The semiconductor device includes a substrate; a fin structure arranged on the substrate and including a ridge portion and a bottom portion between the ridge portion and the substrate, wherein the ridge portion comprises a channel region and a fin region between the channel region and the bottom portion, a critical dimension of the bottom portion in a cross-fin direction is gradually increased toward the substrate to twice or more of a critical dimension of the channel region in the cross-fin direction; a metal gate structure disposed on the fin structure extending the cross-fin direction; and an epitaxy region disposed beside the metal gate structure in a lengthwise direction of the fin structure and connected to the fin structure.
