Abstract: A substrate is provided and a plurality of trenches are formed in the front surface of the substrate. Then, a thermal oxide layer is formed on inner walls of the trenches and the front surface of the substrate. Subsequently, a first structural layer is formed on the thermal oxide layer, dopants are implanted into the first structural layer, a second structural layer is formed on the first structural layer, and an annealing process is performed to reduce the stress of the first and second structural layers. Following that, the first and second structural layers are patterned to form diaphragms. Finally, the second structural layer is mounted on a support wafer with a bonding layer, and the back surface of the substrate is etched by deep etching techniques to form back chambers corresponding to the diaphragms. Each back chamber has a vertical sidewall and partially exposes the first structural layer.

Abstract: A substrate having a sacrificial layer and a structural layer disposed on the front surface of the substrate is provided. Thereon an opening is formed on the back surface of the substrate and the sacrificial layer is exposed partially. A wet etching process is performed to etch the sacrificial layer via the opening to form a suspended structure. Finally, a gas injection process is performed. The gas injection process comprises blowing a gas on the suspended structure via the opening and consequently preventing the suspended structure from sticking to the substrate.

Abstract: Techniques are provided for efficiently processing SOAP requests at a Web service application (WSA) of a multi-functional device (MFP). In one technique, a WSA includes at least three threads. An external request processing thread processes SOAP requests from different client applications. A request processing thread processes a SOAP request according to the business logic of the WSA. A internal communications thread communicates with other components of the MFP that are distinct from the WSA. In another technique, a WSA processes different SOAP request differently, depending on the size of the SOAP and the resources required to process the SOAP request so that fast requests may be processed immediately while slow requests are pending. In another technique, a WS-Eventing specification is implemented within a WSA to simplify the event subscription and notification process.

Abstract: A method and apparatus for communicating with a device is provided. A user views a graphical user interface displayed on a client. For example, the graphical user interface may correspond to a web page or a graphical user interface of an operating system. The graphical user interface may display an icon. The display of the icon may indicate, to the user, whether a device, associated with the icon, is in an energy-saving mode. The user may configure the icon to cause the client to issue requests to the device. A request, sent from the client to the device, may instruct the device to exit the energy-saving mode. In this way, the user may instruct a device to exit the energy-saving mode (i.e., to “wake-up”) prior to issuing a request for the performance of a service (such as a request to print an electronic document) to the device.

Abstract: A method and apparatus for processing electronic documents is provided. A request, from a first user, to issue an alert to a second user that may have submitted a print request to the printing device is received at the printing device. The printing device may be attempting to process the print request submitted by the second user when the printing device receives the request from the first user. The first user may not know the identity of the second user. The printing device consults contact data that identifies how to contact the second user. The printing device thereafter issues the alert to the second user in accordance with the contact data. Upon receiving the alert, the second user is informed of the current condition of the printing device, e.g., the printing device may be experiencing a problem that prevents the second user's print request from being fully processed.

Abstract: A method and mechanism for a client causing an electronic document to be printed without using a printer driver installed on the client is provided. A client discovers one or more printing devices on a network. The client communicates with a discovered printing device to identify the printing features supported by the discovered printing device. When the client receives a request to print an electronic document to a selected printing device, the client sends the electronic document and print configuration data to the selected printing device. As the client has been informed of the printing features supported by the selected printing device, the client can send the electronic document and the print configuration data to the selected printing device in a form readable by the selected printing device. The selected printing device processes the electronic document and the print configuration data to produce a printed copy of the electronic document.
