SEMICONDUCTOR DEVICE - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18086340 Titled 'SEMICONDUCTOR DEVICE'
Simplified Explanation
The abstract describes a semiconductor device that includes a substrate with transistors on it. The transistors are covered by two layers of insulating material. There are two interconnection lines in the device, one in each layer of insulating material. Each interconnection line consists of a barrier pattern, a liner, and a conductive pattern. The height difference between the top surface of the conductive pattern and the top surface of the liner is greater for the first interconnection line than for the second interconnection line.
Original Abstract Submitted
Provided is a semiconductor device including a substrate including an active region, transistors on the substrate, a first interlayer insulating layer and a second interlayer insulating layer on the transistors, a first interconnection line in an upper portion of the first interlayer insulating layer, and a second interconnection line in the second interlayer insulating layer, wherein the first interconnection line includes a first barrier pattern, a first liner, and a first conductive pattern, wherein the second interconnection line includes a second barrier pattern, a second liner, and a second conductive pattern, wherein first height between an uppermost portion of a top surface of the first conductive pattern and a lowermost portion of a top surface of the first liner is greater than a second height between an uppermost portion of a top surface of the second conductive pattern and a lowermost portion of a top surface of the second liner.
