Abstract: A semiconductor package including a ring structure with one or more indents and a method of forming are provided. The semiconductor package may include a substrate, a first package component bonded to the substrate, wherein the first package component may include a first semiconductor die, a ring structure attached to the substrate, wherein the ring structure may encircle the first package component in a top view, and a lid structure attached to the ring structure. The ring structure may include a first segment, extending along a first edge of the substrate, and a second segment, extending along a second edge of the substrate. The first segment and the second segment may meet at a first corner of the ring structure, and a first indent of the ring structure may be disposed at the first corner of the ring structure.

Abstract: A capacitor structure includes a substrate having thereon a storage node contact, a cylinder-shaped bottom electrode disposed on the storage node contact, a supporting structure horizontally supporting a sidewall of the cylinder-shaped bottom electrode, a capacitor dielectric layer conformally covering the cylinder-shaped bottom electrode and the supporting structure, and a top electrode covering the capacitor dielectric layer. The supporting structure has a top surface that is higher than that of the cylinder-shaped bottom electrode. The top surface of the supporting structure has a V-shaped sectional profile.

Abstract: An apparatus for supporting and guiding an optical character reader across a document containing information to be read, such as a business card or an identification card, comprises a frame having a top surface, and a pair of rails disposed on the top surface of the frame, the optical character reader being supported for sliding movement along the rails. An inner guide is located at a forward end of the apparatus. The inner guide includes a slot which receives the optical character reader and acts as a stop for it, thereby determining an initial position of the optical character reader. The top surface of the frame includes an inclined depression which is dimensioned for closely receiving the business or identification card. Desirably, the depression includes a clamping slot along a rear edge thereof into which the business or identification card can be inserted.
