  • Publication number: 20240162313
    Abstract: A method for forming a high electron mobility transistor is disclosed. A mesa structure having a channel layer and a barrier layer is formed on a substrate. The mesa structure has two first edges extending along a first direction and two second edges extending along a second direction. A passivation layer is formed on the substrate and the mesa structure. A first opening and a plurality of second openings connected to a bottom surface of the first opening are formed and through the passivation layer, the barrier layer and a portion of the channel layer. In a top view, the first opening exposes the two first edges of the mesa structure without exposing the two second edges of the mesa structure. A metal layer is formed in the first opening and the second openings thereby forming a contact structure.

  • Publication number: 20240094638
    Abstract: An optimization method for a mask pattern optical transfer includes steps as follows: First, a projection optical simulation is performed to obtain an optimal pupil configuration scheme corresponding to a virtual mask pattern. Next, a position scanning is performed to change the optimal pupil configuration scheme, so as to generate a plurality of adjusted pupil configuration schemes. A mask pattern transfer simulation is performed to obtain a plurality of pupil configuration schemes-critical dimension relationship data corresponding to the virtual mask pattern. Subsequently, an actual pupil configuration scheme suitable for an actual mask pattern is selected according to the plurality of pupil configuration schemes-critical dimension relationship data, and upon which an actual mask pattern transfer is performed.
