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.

Molded image sensor package and method

An image sensor package includes a molding having a locking feature. The package further includes a snap lid having a tab, where the tab is attached to the locking feature of the molding. To form the image sensor package, a window is placed in a pocket of the molding. The snap lid is secured in place. Once secured, the snap lid presses against a peripheral region of an exterior surface of the window. The window is sandwiched between the molding and the snap lid and held in place.

A method of forming an optical module includes mounting an image sensor to a base of a substrate and bonding a lens housing to a sidewall of the substrate. A mounting surface of the lens housing includes a locking feature having a horizontal surface and a vertical surface. The sidewall of the substrate includes a joint surface. To bond the lens housing to the sidewall of the substrate, a bond is formed between the horizontal surface of the locking feature of the lens housing and the joint surface of the sidewall. Further, a bond is formed between the vertical surface of the locking feature of the lens housing and an interior surface of the sidewall.

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.

A marked wafer includes a front-side surface and a back-side surface. A vertical scribe line and a horizontal scribe line are on the front-side surface of the wafer. A back-side alignment mark is located at an intersection of the vertical scribe line and the horizontal scribe line. The back-side alignment mark extends from the front-side surface to the back-side surface of the wafer. The back-side alignment mark is used to aligning a saw, which singulates the wafer from the back-side surface.

Tools and methods for making molded an optical integrated circuit including one or more waveguides are disclosed. In one embodiment, a molding die is provided that includes a substrate that has a topographically patterned first surface. A conformal protective film is provided over the first surface of the substrate. The substrate may be formed of silicon or gallium arsenide, and may be patterned using conventional semiconductor patterning techniques, such as plasma etching. The protective film may be metal (e.g., nickel or titanium), diamond, or some other hard material. Typically, a plurality of such molding dies are formed from a wafer of the substrate material. The die is pressed into a moldable material, such as thermal plastic, to form the wave guide(s) of the optical integrated circuit. A plurality of the dies may be mounted around the curved surface of a heated roller, and a heated tape of the waveguide material may be fed under the roller in a mass production process. Alternatively, the die may be mounted in an injection molding cavity, and the IOC may be formed by an injection molding process.
