    Abstract: An electronic substrate may be fabricated having at least two glass layers separated by an etch stop layer, wherein a bridge is embedded within one of the glass layers. The depth of a cavity formed for embedding the bridge is control by the thickness of the glass layer rather than by controlling the etching process used to form the cavity, which allows for greater precision in the fabrication of the electronic substrate. In an embodiment of the present description, an integrated circuit package may be formed with the electronic substrate, wherein at least two integrated circuit devices may be attached to the electronic substrate, such that the bridge provides device-to-device interconnection between the at least two integrated circuit devices. In a further embodiment, the integrated circuit package may be electrically attached to an electronic board.

    Abstract: Techniques and mechanisms for a micro-LED (or “uLED”) device to facilitate communication of an optical signal which is propagated via a transparent substrate structure. In an embodiment, one or more recess structures are formed in a side of a transparent substrate structure, such as a glass core of a package substrate. A uLED structure extends partially through the transparent substrate structure in a first recess structure, and is oriented to transmit or receive an optical signal via the transparent substrate. In another embodiment, the uLED structure is coupled to integrated circuitry which provides functionality to operate the uLED structure, at different times, in either one of an optical signal receiver mode or an optical signal transmitter mode.

    Abstract: Techniques and mechanisms for a micro-LED (“uLED”) structure to facilitate efficient communication of an optical signal. In an embodiment, a columnar “nanopost” uLED structure comprises contiguous bodies of respective semiconductor materials, including a first body of a doped semiconductor material. The first body forms a pyramidal structure, wherein one or more others of the contiguous bodies are arranged on the first body in a vertically stacked configuration. More particularly, a second body of an undoped semiconductor material is to provide a quantum well of the uLED structure, wherein the second body does not cover or otherwise extend along vertical sidewall structures of the first body. In another embodiment, the pyramidal structure, in combination with the vertically stacked arrangement of semiconductor bodies, facilitates efficient communication of narrowly columnated optical signal by mitigating optical signal communication via vertical sides of the uLED structure.

    Abstract: An electronic substrate may be fabricated having a dielectric material, metal pads embedded in the dielectric material with co-planar surfaces spaced less than one tenth millimeter from each other, and a metal trace embedded in the dielectric material and attached between the metal pads, wherein a surface of the metal trace is non-co-planar with the co-planar surfaces of the metal pads at a height of less than one millimeter, and wherein sides of the metal trace are angled relative to the co-planar surfaces of the metal pads. In an embodiment of the present description, an embedded angled inductor may be formed that includes the metal trace. In an embodiment, an integrated circuit package may be formed with the electronic substrate, wherein at least one integrated circuit devices may be attached to the electronic substrate. Other embodiments are disclosed and claimed.

    Abstract: An integrated circuit package comprising an integral structural member embedded within dielectric material and at least partially surrounding a keep-out zone of a co-planar package metallization layer. The integral structural member may increase stiffness of the package without increasing the package z-height. The structural member may comprise a plurality of intersecting elements. Individual structural elements may comprise conductive vias that are non-orthogonal to a plane of the package. An angle of intersection and thickness of the structural elements may be varied to impart more or less local or global rigidity to a package according to a particular package application. Intersecting openings may be patterned in a mask material by exposing a photosensitive material through a half-penta prism. Structural material may be plated or otherwise deposited into the intersecting openings.
