Abstract:
This disclosure describes optoelectronic modules that include an image sensor having at least two regions separated optically from one another by a wall. The wall can include a bridge portion that extends over the image sensor and further can include a cured adhesive portion, part of which is disposed between a lower surface of the bridge portion and an upper surface of the image sensor. Various techniques are described for fabricating the modules so as to help prevent the adhesive from contaminating sensitive regions of the image sensor. The wall can be substantially light-tight so as to prevent undesired optical cross-talk, for example, between a light emitter located to one side of the wall and a light sensitive region of the image sensor located to the other side of the wall.
Abstract:
The present disclosure describes optoelectronic modules (e.g., hybrid lens array packages) that have multiple optical channels, each of which includes at least one beam shaping element (e.g., a lens) that is part of a laterally contiguous array. Each optical channel is associated with a respective light sensitive region of an image sensor. Some or all of the channels also can include at least one beam shaping element (e.g., a lens) that is not part of a laterally contiguous array. In some cases, the arrays can include alignment features to facilitate alignment of the arrays with one another.

Optoelectronic modules for light emitting and/or light sensing include optical assemblies and active optoelectronic components. An optical assembly and a corresponding optoelectronic component can be aligned. The optoelectronic modules can include multiple optical assemblies and active optoelectronic components. Multiple optical assemblies and corresponding active optoelectronic components can be aligned independently of each other in various implementations of optoelectronic modules that include alignment features and optical assembly barrels.

Abstract:
An optical proximity sensor module includes a substrate, a light emitter mounted on a first surface of the substrate, the light emitter being operable to emit light at a first wavelength, and a light detector mounted on the first surface of the substrate, the light detector being operable to detect light at the first wavelength. The module includes an optics member disposed substantially parallel to the substrate, and a separation member disposed between the substrate and the optics member. The separation member may surround the light emitter and the light detector, and may include a wall portion that extends from the substrate to the optics member and that separates the light emitter and the light detector from one another. The separation member may be composed, for example, of a non-transparent polymer material containing a pigment, such as carbon black.
Abstract:
A spacer wafer for a wafer stack includes a spacer body with a first surface and a second surface, and is intended to be sandwiched between a first wafer and a second wafer. That is, the spacer is to keep a first wafer placed against the first surface and a second wafer placed against the second surface at a constant distance from each other. The spacer provides openings arranged such that functional elements of the first wafer and of the second wafer can be aligned with the openings. The spacer is formed from a forming tool by means of a shape replication process and is preferably made of a material hardened by curing. At least one of the first and second surface includes edges separating the surface from the openings, and the thickness of the spacer wafer at the edges exceeds the thickness of the spacer wafer at surface locations around the edges.
Abstract:
The wafer-level manufacturing method makes possible to manufacture ultrathin optical devices such as opto-electronic modules. A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate, thereon, a photostructurable opaque coating is produced which includes apertures. Then, trenches are produced which extend through the clear encapsulation and establish side walls of intermediate products. Then, an opaque encapsulation is applied to the intermediate products, thus filling the trenches. Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material.

An optoelectronic module assembly includes an optoelectronic module. The module includes: an active optoelectronic component in or on a mounting substrate, an optical sub-assembly, and a spacer disposed between the mounting substrate and the optical sub-assembly so as to establish a particular distance between the active optoelectronic component and the optical sub-assembly. The optoelectronic module assembly also includes a recessed substrate including first and second surfaces, wherein the second surface is in a plane closer to the optical sub-assembly than is the first surface. The optoelectronic module is mounted on the first surface. The second surface is for mounting other components.
