Abstract
A semiconductor structure may include a silicon substrate, a first active device formed in a first region of the silicon substrate, a second active device formed in a second region of the silicon substrate, a first heating device connected thermally to the first active device and a second heating device connected thermally to the second active device. A first temperature sensing device detects a temperature of the first region, a second temperature sensing device detects a temperature of the second region and a circuit activates one of the first heating device and the second heating device in response to a sensed difference in temperature from the first and second temperature sensing devices.
