SEMICONDUCTOR DEVICE STRUCTURE AND METHOD FOR FORMING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18360471 titled 'SEMICONDUCTOR DEVICE STRUCTURE AND METHOD FOR FORMING THE SAME

Simplified Explanation

The abstract describes a semiconductor device structure that includes a transistor, a capacitor, and gate spacer layers. The transistor has a source/drain feature adjoining an active region and a gate stack over the active region. The capacitor is positioned above the transistor and consists of a bottom electrode layer on the gate stack and a ferroelectric layer made of a Hf-based dielectric material on the bottom electrode layer. The gate spacer layers surround the gate stack, bottom electrode layer, and ferroelectric layer.

  • The semiconductor device structure includes a transistor with a source/drain feature and a gate stack.
