摘要:
A semiconductor device includes a main body made of a GaN-based semiconductor material, and at least one electrode structure. The electrode structure includes an ohmic contact layer that is formed on the main body, a buffer layer that is formed on the ohmic contact layer opposite to the main body, and a circuit layer that is made of a copper-based material and that is formed on the buffer layer opposite to the ohmic contact layer. The ohmic contact layer is made of a material selected from titanium, aluminum, nickel, and alloys thereof. The buffer layer is made of a material different from the material of the ohmic contact layer and selected from titanium, tungsten, titanium nitride, tungsten nitride, and combinations thereof.

The present invention relates generally to assembly techniques. According to the present invention, the alignment and probing techniques to improve the accuracy of component placement in assembly are described. More particularly, the invention includes methods and structures to detect and improve the component placement accuracy on a target platform by incorporating alignment marks on component and reference marks on target platform under various probing techniques. A set of sensors grouped in any array to form a multiple-sensor probe can detect the deviation of displaced components in assembly.

An electronic device is disclosed for coupling to a target platform, which includes a multitude of pad contacts. The electronic device includes a substrate, a multitude of pad contacts on the substrate, and a multitude of contact regions in one of the of pad contacts on the substrate. Each of the multitude of pad contacts on the substrate electrically couples to a corresponding one of the multitude of pad contacts on the target platform when the substrate and the target platform are assembled. The multitude of contact regions corresponds to one of the multitude of pad contacts on the target platform when the substrate and the target platform are assembled.

A controller architecture optimized for processing audio and video information in playback systems used for reproducing information stored on optical discs such as CDs and DVDs. The controller uses a unique parallel interface to facilitate the transfer of CD data and DVD data from the controller to a MPEG decoder. The controller also performs servo control operations, data processing and error detection and correction operations for CD data and DVD data, and provides shared memory resources for internal operations of the controller. DVD/CD playback systems incorporating the present invention occupy less real estate, have smaller pin counts, are less complex, and are cheaper to manufacture than conventional playback systems.

A non-volatile memory module in parallel architecture is described. It includes memory function and data storage function in a single module. It enables host system to use memory bus to access storage devices and to use the same memory command protocol for storage device access. The parallel architecture enables contents in memory devices and storage devices to be exchanged freely on module under the control of host memory controller to boost performance of computer and to retain data even if power to computer is shut off. The configuration of non-volatile memory module can be partitioned or expanded into multiple independent channels on module seamlessly with or without ECC supports.
