Latest Patents

Kyu Hyun Lee's latest patents include a semiconductor device that features a device isolation layer defining an active region. This device incorporates a first trench in the device isolation layer and a second trench in the active region. It also includes a main gate electrode structure that fills a portion of the first trench, consisting of a first barrier conductive layer and a main gate electrode. Additionally, there is a pass gate electrode structure that fills a portion of the second trench, which includes a second barrier conductive layer and a pass gate electrode. A support structure fills another portion of the second trench above the pass gate electrode, while a first capping pattern fills another portion of the first trench above the main gate electrode. Furthermore, a second gate insulating layer extends along the bottom and sidewall of the second trench, with the second barrier conductive layer positioned between the second gate insulating layer and the pass gate electrode.

Another notable patent is for a semiconductor device and method for fabricating the same. This invention includes an element isolation region and a first active region bounded by the element isolation region. The first active region extends in a first direction and comprises first and second parts at a first level, along with a third part at a second level above the first level. A gate electrode is disposed inside both the element isolation region and the first active region, extending in a second direction different from the first direction. The second part is spaced apart from the first part in the first direction, while the third part contacts both the first and second parts. The first width in the second direction of the first part is less than the second width in the second direction of the third part.
