Abstract:
An image sensor package includes an image sensor, a window, and a molding, where the molding includes a lens holder extension portion extending upwards from the window. The lens holder extension portion includes a female threaded aperture extending from the window such that the window is exposed through the aperture. A lens is supported in a threaded lens support. The threaded lens support is threaded into the aperture of the lens holder extension portion. The lens is readily adjusted relative to the image sensor by rotating the lens support.
Abstract:
A mounting for a package containing a semiconductor chip is disclosed, along with methods of making such a mounting. The mounting includes a substrate having a mounting surface with conductive traces thereon, and an aperture extending through the substrate. The package includes a base, such as a leadframe or a laminate sheet, and input/output terminals. A chip is on a first side of the base and is electrically connected (directly or indirectly) to the input/output terminals. A cap, which may be a molded encapsulant, is provided on the first side of the base over the chip. The package is mounted on the substrate so that the cap is in the aperture, and a peripheral portion of the first side of the base is over the mounting surface so as to support the package in the aperture and allow the input/output terminals of the package to be juxtaposed with to the circuit patterns of the mounting surface. Because the cap is within the aperture, a height of the package above the mounting surface is minimized.
Abstract:
An image sensor package includes a substrate and an image sensor coupled to the substrate. The image sensor includes an upper surface having an active area. A reflector lid is coupled to the substrate. The reflector lid has a first panel having a planar surface. The planar surface is at least partially reflective and is angled relative to the upper surface of the image sensor to reflect electromagnetic radiation to the active area of image sensor.
Abstract:
A thin image sensor package includes an image sensor having an active area which is responsive to radiation. The image sensor is mounted to a substrate which is transparent to the radiation. The image sensor is mounted such that the active area of the image sensor faces the substrate. Of importance, the substrate serves a dual function. In particular, the substrate is the window which covers the active area of the image sensor. Further, the substrate is the platform upon which the image sensor package is fabricated. As a result, the image sensor package is thin, lightweight and inexpensive to manufacture.
Abstract:
An electronic device, such as a sensor die, is packaged by first forming a hole through a substrate. The hole is made large enough to position the entire electronic device within the hole. A tape is then applied to the second surface of the substrate to cover a second side of the hole, thereby creating a tape surface at the bottom of the hole. The electronic device is then positioned within the hole such that the electronic device is in contact with, and adhered to, the tape surface at the bottom of the hole. Electronic connections are made between the electronic device and the substrate and a layer of encapsulant is applied. In one embodiment, the electronic device is a sensor die and an optical element is positioned over an active region of the sensor die before the encapsulant is applied. The encapsulant then surrounds and holds the optical element in position over the active region of the sensor die.
Abstract:
A protective layer includes a polymerized region, which forms a cavity in an interior surface of the protective layer. The protective layer is mounted to a micromachine chip such that an active area of the micromachine chip is located within the cavity of the protective layer. The protective layer protects the active area during front-side or back-side singulation of the micromachine chip from a micromachine substrate.
Abstract:
A vacuum sealed package for a semiconductor chip, such as a micro-electromechanical (MEM) chip, is disclosed, along with a method of making such a package. In an exemplary embodiment, the package includes a ceramic substrate and a lid that together define a cavity wherein the chip is mounted. The substrate includes a conductive (e.g., metal) interconnect pattern that extends, at least in part, vertically through the substrate. I/O terminals are provided on an external surface of the substrate. A vent hole, at least partially lined with a metal coating, extends through the substrate into the cavity. A metal plug seals the vent hole. The vent hole is sealed by placing the package in a vacuum chamber, evacuating the chamber, and heating the chamber so as to cause a metal preform on the substrate to flow into the vent hole and form the plug.

Abstract:
A drop is applied to an active area of an image sensor. A window is pressed into the drop to form a window support. The window support is then cured, or otherwise set-up, to form an image sensor package. During use, radiation is directed at the image sensor package. This radiation passes through the window, passes through the window support, and strikes the active area, which responds to the radiation. The window and the window support are transparent to the radiation.
