Abstract: A method includes forming a first semiconductor channel region and a second semiconductor channel region, with the second semiconductor channel region overlapping the first semiconductor channel region, forming a first gate dielectric on the first semiconductor channel region, and forming a second gate dielectric on the second semiconductor channel region. A dipole dopant is incorporated into a first one of the first gate dielectric and the second gate dielectric to a higher atomic percentage, and a second one of the first gate dielectric and the second gate dielectric has a lower atomic percentage of the dipole dopant. A gate electrode is formed on both of the first gate dielectric and the second gate dielectric. The gate electrode and the first gate dielectric form parts of a first transistor, and the gate electrode and the second gate dielectric form parts of a second transistor.

Abstract: A method includes forming a first gate stack including forming a first interfacial layer over a first semiconductor region, wherein the first interfacial layer has a first thickness; and forming a first high-k dielectric layer over the first interfacial layer, wherein the high-k dielectric layer has a second thickness.

The thicknesses, dopants, and doping concentrations of the first interfacial layer and the second interfacial layer may be different from each other. The thicknesses, dopants, and doping concentrations of the first high-k dielectric layer and the second high-k dielectric layer may be different from each other.

Abstract: A method includes forming a dummy gate stack on a semiconductor region, forming gate spacers on sidewalls of the dummy gate stack, removing the dummy gate stack to form a recess between the gate spacers, and forming a silicon oxide layer on the semiconductor region. The silicon oxide layer extends into the recess. A high-k dielectric layer is deposited over the silicon oxide layer, and a silicon layer is deposited over the high-k dielectric layer. The silicon layer extends into the recess. The high-k dielectric layer and the silicon layer are in-situ deposited in a same vacuum environment. The method further includes performing an annealing process on the silicon layer and the high-k dielectric layer, removing the silicon layer, and forming a gate electrode over the high-k dielectric layer. The gate electrode fills the recess.

Abstract: The disclosure provides a light-emitting element inspection device optically connected to at least one light-emitting element of a test object and including a dark box, a slide rail, an image-capturing device, a light-entrance plate, and a processor. The slide rail and the image-capturing device are disposed in the dark box. The image-capturing device slides on the slide rail. The light-entrance plate is disposed on one side of the dark box and has at least one hole optically connected to the light-emitting element. The image-capturing device is aligned with the light-entrance plate to capture an image of the light-entrance plate. The processor is coupled to the image-capturing device and is adapted to obtain a set of RGB values of the image, convert the RGB values into a set of HSV values, and determine whether the light-emitting element of the test object conforms to a standard based on the HSV values.
