Abstract:
In accordance with an embodiment, a cascode connected semiconductor component and a method for manufacturing the cascode connected semiconductor component are provided. The cascode connected semiconductor component has a pair of silicon based transistors, each having a body region, a gate region over the body region, a source region and a drain. The source regions of a first and second silicon based transistor are electrically connected together and the drain regions of the first and second silicon based transistors are electrically connected together. The gate region of the second silicon based transistor is connected to the drain regions of the first and second silicon based transistors. The body region of the second silicon based transistor has a dopant concentration that is greater than the dopant concentration of the first silicon based transistor. A gallium nitride based transistor has a source region coupled to the first and second silicon based transistor.
