Abstract: An integrated circuit package includes an angled one-piece substrate having a light source fixed to one area and a sensor die fixed to a second area, such that the light source is directed to illuminate the field of view of the sensor die when a surface of interest is imaged. The integrated circuit package is well suited for generating navigation information regarding movement relative to a surface. In one method of forming the integrated circuit package, the single-piece substrate is originally a generally flat lead frame to which the sensor die and light source are attached. After the components have been connected, the lead frame is bent to provide the desired light source-to-sensor angle. In an alternative method, the lead frame is pre-bent. For either method, optics may be connected to the integrated circuit package, thereby providing a module that includes the optics, the light source, the sensor and the packaging body.

Abstract: Flip-chips are aligned by making a fiducial in the “top” chip that is translucent/transparent to light of a wavelength shorter than infrared, and at least one corresponding fiducial in the “bottom” chip. The top-chip fiducial may be made of a transparent or translucent material, its shape may be outlined by an opaque material, or it may be formed by etching through the top chip. The bottom-chip fiducial may be reflective of the light which is transparent/translucent to the fiducial in the top chip, in which case alignment can be achieved by employing at least one video camera which is located above the top chip. Alternatively, the fiducial in the bottom chip may also be transparent/translucent to the light, in which case alignment can be achieved by having the video camera located below the bottom chip. The chips are aligned by aligning the fiducials as seen by the video camera.

A source doped region (60) is positioned in the semiconductor substrate (12) adjacent to one of the select gates for providing a source of electrons to be injected into a storage layer (42) underlying the control gate. Lower programming results from the SSI method of programming and a compact memory cell size exists.

The first insulator layer is deposited in a manner to define at least one notch along its edge.

A conductive filler can optionally be deposited in each via hole. Lastly, a second conductive layer can be deposited over the first insulator layer, the second insulator layer and, if provided, the conductive filler.

In one exemplary process, the process includes loading a semiconductor substrate into a process chamber. First main process gases, including a silicon source gas, an oxygen gas, a nitrogen free chemical etching gas and a hydrogen gas, are then injected into the process chamber.

In addition, the first main process gases can be replaced with second main process gases including a silicon source gas, an oxygen gas, a nitrogen free chemical etching gas, a hydrogen gas and a helium gas.
