The present disclosure provides a semiconductor structure, including a capacitor. The capacitor includes a first electrode and a second electrode respectively electrically connected to a first conductor and a second conductor; and a first dielectric layer between the first electrode and the second electrode. In some embodiments, the first dielectric layer contacts with a sidewall surface of the first conductor. The semiconductor structure further includes a second dielectric layer over and adjacent to the capacitor. A method of forming the semiconductor package is also provided.

Semiconductor structure and method of forming the same

Semiconductor structure and method of forming semiconductor package

The present disclosure provides a semiconductor package, including at least two conductors and a first dielectric partially surrounding the at least two conductors, a capacitor substantially under the first dielectric, and a second dielectric over and lining along the first dielectric and top portions of the at least two conductors. The at least two conductors are respectively configured as an input/output (I/O) terminal of the semiconductor package. The capacitor includes a first electrode extending along a first direction and electrically connected with one of the at least two conductors, and a second electrode extending along a second direction opposite to the first direction and electrically connected to the other one of the at least two conductors. The second dielectric provides a compressive stress to the first dielectric. A method of forming the semiconductor package is also provided.

Semiconductor package and method of forming the same

A test structure to detect vertical leakage in a multi-layer flip chip pad stack or similar semiconductor device. The test structure is integrated into the semiconductor device when it is fabricated. A metal layer includes at least two portions that are electrically isolated from each other; one portion being disposed under a test pad, and another portion being disposed under a pad associated with a pad structure being tested. The metal layer in most cases is separated from a top metal layer directly underlying the pads by an inter-metal dielectric (IMD) layer. A metal layer portion underlying the pad to be tested forms a recess in which a conductive member is disposed without making electrical contact. The conductive line is electrically coupled to a test portion of the same or, alternately, of a different metal layer. The test structure may be implemented on multiple layers, with recesses portions underlying the same or different pads.
