Abstract
A semiconductor device includes at least a direct backside contact between a source line and a source epitaxial growth and/or a drain line and a drain epitaxial growth. A clock signal line contact via can connect a gate to a backside clock signal line. The clock signal line contact via is surrounded by a deep STI fill to prevent shorting between the clock signal line and the source and/or drain lines in the backside power rail.
