Substrates with continuous slot vias are disclosed herein. In one embodiment, a substrate comprises a first design layer, a second design layer, and an intermediary layer between the first and second design layers. The substrate further includes first and second signaling vias extending vertically through the intermediary layer between the first and second design layers. The first and second signaling vias route first and second data signals, respectively, between the first and second design layers. The substrate further includes a slot via that is positioned between the first and second signaling vias within the intermediary layer and extends laterally within the intermediary layer along a path that passes between the first signaling via and the second signaling via. The slot via can have a continuous shape such that the slot via shields the first and second data signals on the first and second signaling vias from crosstalk with one another.

Substrates with continuous slot vias

Apparatuses, such as semiconductor device packages, may include, for example, a device substrate including a semiconductor material and bond pads coupled with an active surface of the device substrate. A package substrate may be secured to the device substrate, the package substrate configured to route signals to and from the bond pads. A ball grid array may be supported on, and electrically connected to, the package substrate. Each ball of the ball grid array positioned and configured to carry a clock signal or a strobe signal may be located in a central column of the ball grid array.

A method and apparatus for improving the laminate performance of the solder balls in a BGA package. Specifically, the ball pads on the substrate are configured to increase the shear force necessary to cause delamination of the solder balls. Conductive traces extending planarly from the pads and arranged in specified configurations will increase the shear strength of the pad.

A semiconductor component includes a stiffener, a circuit decal attached to the stiffener, and a semiconductor die attached to the stiffener. The circuit decal includes conductors which function as an internal signal transmission system for the component, and a mask layer which functions as a solder mask and an outer insulating layer for the component. An adhesive layer in physical contact with the conductors attaches the circuit decal to the stiffener, and electrically insulates the conductors from the stiffener. The component also includes an area array of terminal contacts on the conductors electrically isolated by the mask layer. A method for fabricating the component includes the steps of attaching the circuit decal to the stiffener, attaching the die to the stiffener, interconnecting the die and the circuit decal, encapsulating the die, and forming the terminal contacts.

A method and apparatus for supporting a microelectronic substrate. The apparatus can include a microelectronic substrate and a support member carrying the microelectronic substrate. The apparatus can further include a first connection structure carried by the support member. The first connection structure can have a first bond site configured to receive a flowable conductive material, and can further have at least two first elongated members connected and extending outwardly from the first bond site. Each first elongated member can be configured to receive at least a portion of the flowable conductive material from the first bond site, with none of the first elongated members being electrically coupled to the microelectronic substrate. The assembly can further include a second connection structure that is electrically coupled to the microelectronic substrate and that can include second elongated members extending away from a second bond site. The number of second elongated members can be equal to the number of first elongated members.

The invention encompasses methods of preparing interposers for utilization in semiconductor packages. The invention includes a method in which an interposer substrate having a surface and a conductive layer extending over the surface is provided. Pads are formed on the conductive layer by plating a conductive material on the conductive layer while using the conductive layer as an electrical connection to a power source and without utilizing conductive busses, other than the conductive layer. Subsequent to the formation of the pads, the conductive layer is patterned into circuit traces. Methodology of the present invention can be utilized for, for example, forming board-on-chip constructions.
