Oh’s listed patents address semiconductor structures and thermal management in power devices.

“Semiconductor device sidewall of the gate semiconductor layer including a plurality of surfaces having different slopes” describes a semiconductor device with a gate semiconductor layer positioned between a barrier layer and a gate electrode. The layer’s sidewall connects its lower and upper surfaces, which differ in area, and includes multiple surfaces with different slopes. The design also incorporates a channel layer, source, and drain.

“Power device and method of manufacturing the same” describes a power device built on a substrate with an epitaxially grown compound semiconductor layer, a gate, and source and drain electrodes. Its substrate includes a cooling-space region designed to form an internal cooling path. The region has an enlargement whose width increases with depth, while its inlet is narrower than its maximum width.
