A method of forming an assembly is provided. The method includes attaching a packaged semiconductor device to a substrate. An isolation structure is formed and located between the packaged semiconductor device and the substrate. An underfill material is dispensed between the packaged semiconductor device and the substrate. The isolation structure prevents the underfill material from contacting a first conductive connection formed between the packaged semiconductor device and the substrate.

A semiconductor package includes a semiconductor die including circuitry electrically coupled to bond pads that is mounted onto a leadframe. The leadframe includes a plurality of leads and a dam bar having a transverse portion that extends between adjoining ones of the leads. The bond pads are electrically connected to the plurality of leads. A raised dam pattern is on the dam bar or on an edge of an exposed portion of a top side clip of the semiconductor package that is positioned above and connects to the semiconductor die. The raised dam pattern includes a first material that is different relative to the material of the dam bar or the clip. A mold material encapsulates the semiconductor die.

A semiconductor device includes: a first electrode provided on a semiconductor multilayer structure; a second electrode provided on a substrate; and a bonding metal layer which bonds the first electrode and the second electrode together. The bonding metal layer includes a gap inside.

A semiconductor element includes first/second electrodes on an element obverse surface, an insulating layer on the element obverse surface, and first/second electrode terminals in contact with the first/second electrodes, respectively. The insulating layer includes first/second openings, and first/second overlapping portions adjoining the first/second openings, respectively. The first/second openings expose the first/second electrodes, respectively. The first/second overlapping portions overlap with the first/second electrodes, respectively, as viewed in a thickness direction. The first/second electrode terminals are in contact with the first/second electrodes, respectively, through the first/second openings, while also overlapping with the first/second overlapping portions as viewed in the thickness direction. The first electrode terminals are in a region with a high arrangement density of electrode terminals, whereas the second electrode terminals are in a region with a low arrangement density of electrode terminals. Each first overlapping portion has a greater dimension in the thickness direction than each second overlapping portion.

Lead frames for semiconductor device packages may include lead fingers proximate to a die-attach pad. A convex corner of the lead frame proximate to a geometric center of the lead frame may be rounded to include a radius of curvature of at least two times a greatest thickness of the die-attach pad. The thickness of the die-attach pad may be measured in a direction perpendicular to a major surface of the die-attach pad. A shortest distance between the die-attach pad and each one of the lead fingers having a surface area larger than an average surface area of the lead fingers may be at least two times the greatest thickness of the die-attach pad.

A chip package structure is provided. The chip package structure includes a wiring substrate. The chip package structure includes a first chip structure and a second chip structure over the wiring substrate. The first chip structure is spaced apart from the second chip structure by a gap. The chip package structure includes a ring structure over the wiring substrate.

An apparatus is described. The apparatus includes I/O structures having pads and solder balls to couple with a semiconductor chip, wherein, a first subset of pads and/or solder balls of the pads and solder balls that approach the semiconductor chip during coupling of the semiconductor chip to the I/O structures are thinner than a second subset of pads and/or solder balls of the pads and solder balls that move away from the semiconductor chip during the coupling of the semiconductor chip to the I/O structures.

A method of forming an assembly is provided. The method includes attaching a packaged semiconductor device to a substrate. An isolation structure is formed and located between the packaged semiconductor device and the substrate. An underfill material is dispensed between the packaged semiconductor device and the substrate.
