Abstract: A package structure includes a first RDL, an adhesive layer and a first electronic component. Upper bumps and conductive pads are provided on a first upper surface and a first lower surface of the first RDL, respectively. The adhesive layer is located on the first upper surface of the first RDL and surrounds the upper bumps. The first electronic component is mounted on the adhesive layer and includes conductors which are visible from an active surface of the first electronic component and joined to the upper bumps, the active surface of the first electronic component faces toward the first upper surface of the first RDL. Two adhesive surfaces of the adhesive layer are adhered to the first upper surface of the first RDL and the active surface of the first electronic component, respectively.

Abstract: Various embodiments of the present disclosure are directed towards a memory device including a first bottom electrode layer over a substrate. A ferroelectric switching layer is disposed over the first bottom electrode layer. A first top electrode layer is disposed over the ferroelectric switching layer. A second bottom electrode layer is disposed between the first bottom electrode layer and the ferroelectric switching layer. The second bottom electrode layer is less susceptible to oxidation than the first bottom electrode layer.

Abstract: A color wheel includes a fixing base, a ring filter, a washer, and a fixing ring. The fixing base has a protrusion portion and a supporting portion. The ring filter is fit on the protrusion portion. An inner margin of the ring filter leans on the supporting portion. The washer is connected to the protrusion portion. The ring filter is disposed between the washer and the supporting portion. The washer and the supporting portion clip the inner margin of the ring filter. The fixing ring has an annular supporting portion, a side wall surrounding the annular supporting portion, and fixing blocks connected to the side wall and dotted on an outer margin of the ring filter. The outer margin of the ring filter leans on the annular supporting portion. The fixing blocks, the side wall, and the annular supporting portion clip the outer margin of the ring filter.
