Abstract
Methods and apparatus providing a vertically constructed, temperature sensing resistor are disclosed. An example apparatus includes a semiconductor substrate including a first doped region, a second doped region, and a third doped region between the first and second doped regions, the third doped region including a temperature sensitive semiconductor material; a first contact coupled to the first doped region; a second contact opposite the first contact coupled to the second doped region; and an isolation trench to circumscribe the third doped region.
