Abstract: A method for fabricating semiconductor devices includes forming channel regions over a substrate. The channel regions, in parallel with one another, extend along a first lateral direction. Each channel region includes at least a respective pair of epitaxial structures. The method includes forming a gate structure over the channel regions, wherein the gate structure extends along a second lateral direction. The method includes removing, through a first etching process, a portion of the gate structure that was disposed over a first one of the channel regions. The method includes removing, through a second etching process, a portion of the first channel region. The second etching process includes one silicon etching process and one silicon oxide deposition process. The method includes removing, through a third etching process controlled based on a pulse signal, a portion of the substrate that was disposed below the removed portion of the first channel region.

Abstract: The present invention relates to a method of treating moderate or severe symptoms of COVID-19 using a plant composition. The plant composition comprises Prepared Monkshood Daughter Root (Aconitum carmichaelii), Fragrant Solomonseal Rhizome (Polygonatum odoratum), Indian Bread (Poria cocos), Pinellia tuber (Pinellia ternata), Oriental Wormwood Herb (Artemisia scoparia), Scutellaria Root (Scutellaria baicalensis), Mongolian Snakegourd Fruit (Trichosanthes kirilowii), Magnolia Bark (Magnolia officinalis), Heartleaf Houttuynia Herb (Houttuynia cordata), and Baked Licorice Root and Rhizome (Glycyrrhiza glabra), which is used as a traditional Chinese medicine composition.
