Electrode structure of compound semiconductor device
An electrode structure of compound semiconductor device. The compound semiconductor device has a substrate, an n-type layer over entire substrate, a mesa-like p-type layer on partial surface of the n-type layer, a transparent conductive layer on the mesa-like p-type layer; a p-contact formed on the transparent conductive layer and an n-contact formed on the exposed n-type layer. The n-contact comprises an enclosure portion compassing the p-contact, whereby the current flowed from the p-contact to the n-contact is uniform.
