Abstract
A circuit board with embedded resistors and a method for fabricating the same are provided. The circuit board includes the circuit substrate and the variable resistor region. The variable resistor region includes the first resistor layer, the second resistor layer and the liquid metal material. The first resistor layer is electrically connected to the circuit substrate, and the second resistor layer overlaps the first resistor layer. The liquid metal material is located on and is electrically connected to the first resistor layer. The liquid metal material is spaced from the second resistor layer without any electrical connection under the initial temperature. The liquid metal material is electrically connected to the second resistor layer under the first temperature which is higher than the initial temperature.
