Abstract:
A low-cost resin lens is disclosed for use in miniature cameras. The resin lens features a low profile that is particularly well-suited to consumer products such as smart phones. The resin lens is mounted to an integrated circuit die that is attached to a standard four-layer substrate. The integrated circuit die includes electronic and/or optoelectronic circuits to support digital image capture, transfer, and processing. Image correction software adjusts the image to correct for distortion introduced by the resin lens.

Abstract:
Described herein are various embodiments of contacts that include different portions angled with respect to one another and methods of manufacturing devices that include such contacts. In some embodiments, a module may include a first portion of a contact that is disposed within a housing and a second portion that is disposed outside of the housing, with the second portion angled with respect to the first portion. Manufacturing such devices may include depositing a conductive material to electrically connect the contact to a contact pad of a substrate. In some embodiments, a deposition process for depositing the conductive material may have a minimum dimension, which defines a minimum dimension of a conductive material once deposited. In some such embodiments, a distance between a terminal end of the contact pin and the contact pad may be greater than the minimum dimension of the deposition process.

One or more embodiments disclosed herein are directed to a chip scale package camera module that includes a glass interposer between a lens and an image sensor. In some embodiments, the glass interposer is made from one or more layers of optical quality glass and includes an infrared filter coating. The glass interposer also includes electrically conductive paths to connect the image sensor, mounted on one side of the glass interposer, with other components such as capacitors, which may be mounted on a different side of the glass interposer, and the rest of the camera system. The conductive layers include traces and vias that are formed in the glass interposer in areas away from the path of light in the camera module, such that the traces and vias do not block the light between the lens and the image sensor.

Abstract:
An optical detection sensor functions as a proximity detection sensor that includes an optical system and a selectively transmissive structure. Electromagnetic radiation such as laser light can be emitted through a transmissive portion of the selectively transmissive structure. A reflected beam can be detected to determine the presence of an object. The sensor is formed by encapsulating the transmissive structure in a first encapsulant body and encapsulating the optical system in a second encapsulant body. The first and second encapsulant bodies are then joined together. In a wafer scale assembling the structure resulting from the joined encapsulant bodies is diced to form optical detection sensors.
