Abstract: A semiconductor package may include a first substrate including a first connection portion disposed on a surface of the first substrate and a second substrate including a second connection portion disposed on a surface of the second substrate. The second substrate may be disposed over the first substrate and the second connection portion facing the first connection portion. A first connection loop portion may be provided to include an end connected to the first connection portion. A second connection loop portion may be provided to include one end connected to the second connection portion and the other end combined with the first connection loop portion.

Abstract: The semiconductor package includes an upper semiconductor chip stacked on a package substrate and a support layer or a lower semiconductor chip disposed between the upper semiconductor chip and the package substrate. The upper semiconductor chip includes a protrusion downwardly extending from an edge thereof. The protrusion of the upper semiconductor chip is combined with a sidewall of the support layer or the lower semiconductor chip. Related methods are also provided.

Abstract: Methods of forming an interconnection line pattern using a screen printing technique. The method includes preparing a substrate having unevenness, aligning a stencil mask on the substrate, and printing a paste including materials for forming the interconnection line pattern on a convex portion of the unevenness formed on the substrate.
