Latest Patents

One of Lee's latest patents is focused on a transistor and a method of manufacturing the same. This invention includes a dummy structure that encloses source/drain structures and channel structures. As a result, a gate electrode of the transistor can be efficiently formed over the channel structures. Additionally, the source/drain structure is designed to prevent excessive growth during the epitaxial growth process used for forming the source/drain structure.

Another notable patent is for a power supply of a display apparatus that incorporates a universal serial bus (USB) device. This power supply features a switching mode power supply that serves as the main power source for the display apparatus. It also includes an auxiliary power supply for providing power through a USB hub. The invention is equipped with a display power management signaling (DPMS) control circuit that manages power-saving modes, including full-on, standby, suspend, and power-off. The DPMS control circuit responds to synchronization signals and produces a control signal that cuts off the relay switch in power-off mode, ensuring a stable power supply even when the display apparatus is turned off.
