More Information
Summary:A high electron mobility transistor device including a channel layer, a first barrier layer, a gate structure, and a spacer is provided. The first barrier layer is disposed on the channel layer. The gate structure is disposed on the first barrier layer. The gate structure includes a first P-type gallium nitride layer, a second barrier layer, and a second P-type gallium nitride layer. The first P-type gallium nitride layer is disposed on the first barrier layer. The second barrier layer is disposed on the first P-type gallium nitride layer. The second P-type gallium nitride layer is disposed on the second barrier layer. A width of the second P-type gallium nitride layer is smaller than a width of the first P-type gallium nitride layer. The spacer is disposed on a sidewall of the second P-type gallium nitride layer.
