Abstract: A method includes forming a first fin and a second fin protruding from a frontside of a substrate, forming a gate stack over the first and second fins, forming a dielectric feature dividing the gate stack into a first segment engaging the first fin and a second segment engaging the second fin, and growing a first epitaxial feature on the first fin and a second epitaxial feature on the second fin. The dielectric feature is disposed between the first and second epitaxial features. The method also includes performing an etching process on a backside of the substrate to form a backside trench, and forming a backside via in the backside trench. The backside trench exposes the dielectric feature and the first and second epitaxial features. The backside via straddles the dielectric feature and is in electrical connection with the first and second epitaxial features.

Abstract: The present invention relates to the use of compounds of formula (I) and formula (II) and/or pharmaceutically acceptable salts of the aforementioned compounds in the treatment of meningioma and the reduction of the recurrence rate of meningioma.

Abstract: The present invention discloses an LED lens and a light source device using the same. The light source device includes the LED lens and a LED. The LED lens comprises a light incident surface, a light emitting surface, and a bottom surface. The light emitting surface includes a recession portion disposed at the central thereof and a convex portion connected to the recession portion. The light incident surface is a concave surface and comprises a first optically active area and a second optically active area. The first optically active area is disposed at the central of the light incident surface; the second optically active area is connected to the first optically active area and the bottom surface. At the junction between the first optically active area and the second optically active area, it is an optical path inversion point that is disposed satisfying specific condition.
