Abstract
A memory cell includes a substrate, a word line, a first source/drain region, a second source/drain region, a first conductive via, and a second conductive via. The word line is arranged within the substrate. The first source/drain region and the second source/drain region are disposed in the substrate and on opposite sides of the word line. The first conductive via is disposed on the first source/drain region. The second conductive via is disposed on the second source/drain region. The second conductive includes a lower portion and an upper portion. The lower portion is extending into the second source/drain region. The upper portion is disposed over the lower portion.
