  • Publication number: 20080283844
    Abstract: An opening for forming a gate electrode is provided by a first photoresist pattern formed on an insulating film. Reactive ion etching by inductively coupled plasma is applied to the insulating film through the first photoresist pattern as a mask to thereby expose the surface of a GaN semiconductor layer, evaporating thereon a gate metal such as NiAu, thereby forming the gate electrode by self-aligned process. This prevents an oxidized film from being formed on the surface of the semiconductor layer. After the gate electrode is formed, a second photoresist pattern is formed to form a field plate on the gate electrode and the insulating film through the second photoresist pattern as a mask. Thereby, Ti having a high adhesiveness with an insulating film made of SiN or the like can be used as a field plate metal.

    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: Noise occurring in a circuit is more accurately detected. A low-pass filter (11) is connected to a power supply line for a power supply terminal (VDD), and noise in the power supply line is removed to generate and output a referential voltage (V0). A high-pass filter (12) is connected to a power supply line, and a noise signal in the power supply line is passed with the referential voltage (V0) as a reference. A high-pass filter (13) is connected to a ground line for a ground terminal (GND), and a noise signal in the ground line is passed based on the referential voltage (V0) as a reference. A reference voltage generation circuit (14) generates and outputs a reference voltage (Vref) based on the referential voltage (V0) as a reference. Comparison circuits (CMP1 and CMP2) respectively compare output voltage of the high-pass filters (12 and 13) and the reference voltage (Vref).

    Abstract: A transistor having a gate dielectric layer of partial thickness difference and a method of fabricating the same are provided. The method includes forming a gate dielectric layer having a main portion with a relatively thin thickness formed on a semiconductor substrate, and a sidewall portion with a relatively thick thickness formed on both sides of the main portion. A first gate is formed overlapping the main portion of the gate dielectric layer, and forming a second gate layer covering the sidewall portion of the gate dielectric layer and covering the first gate. The second gate layer is etched, thereby forming second gates patterned with a spacer shape on sidewalls of the first gate. The exposed sidewall portion of the gate dielectric layer is selectively etched using the second gates as a mask, thereby forming a pattern of the gate dielectric layer to be aligned with the second gates. A source/drain is formed in a portion of the semiconductor substrate exposed by the second gates.
