According to one embodiment, the method includes (1) providing a substrate of a first conductivity type including a first active region for said first lateral high-voltage MOS transistor and a second active region for said second lateral high-voltage MOS transistor and (2) forming at least one first doped region of the first conductivity type in the first active region and forming in the second active region a drain extension region of the second conductivity type extending from a substrate surface to an interior of the substrate, including a concurrent implantation of dopants through openings of one and the same mask into the first and second active regions. Forming of the at least one first doped region may be a sub step of a superior step of forming a double RESURF structure in the first lateral high-voltage MOS transistor, and forming the double RESURF structure may include forming doped RESURF regions as two first doped regions, one thereof above and one thereof below the drift region of the first lateral high-voltage MOS transistor, and as two further doped regions, one thereof above and one thereof below the drain extension regions of the second lateral high-voltage MOS transistor, wherein the first doped RESURF regions have an inverse conductivity type with respect to the drift region and the further doped regions have inverse conductivity type as compared to the drain extension region.

The invention is intended to specify an electrical measuring method for an operating temperature and a modified component for carrying out the method which improves the monitoring of the component. Measured temperature values are intended to be delivered without any time delay and without requiring additional surfaces for temperature sensors. Location-related temperature values need to be able to be measured. The invention proposes a method for said location-related electrical measurement of the operating temperature of a likewise proposed MOS power component with a gate electrode network comprising a material whose temperature coefficient of the electrical resistance is known. The gate electrode network is divided into a plurality of measuring sections with contact point pairs which are respectively connected to contacts (71.1, 72.1; 71.2, 72.2; 71.3, 7; 72.3, 7). The contact points in each contact point pair are at a certain distance from one another, and each of the measuring sections situated between the contact point pairs is respectively electrically insulated from the other measuring sections, so that there is no electrical influencing between the measuring sections. The electrical resistances of the measuring sections are measured directly on the gate electrode network during the operation of the semiconductor power component when gate voltages are applied between the contact points of the gate electrode (4) using measuring voltages (u1, u2, u3) superimposed on the gate voltages. The electrical resistances of the measuring sections are used to determine the temperatures of the MOS semiconductor power component on the measuring sections.
摘要:
A method and system for delivering and displaying content on a mobile handheld device with voice telephony capability. Content is received from or on behalf of a content provider. For each individual one of a plurality of mobile handheld devices, content appropriate for each device is determined. The content determined to be appropriate for each mobile handheld device is delivered individually to that mobile handheld device. It is then determined whether the mobile handheld device is in an internal and/or external predetermined status, wherein the internal predetermined status is a function of the mobile handheld device unrelated to the content. If the mobile handheld device is in the internal and/or external predetermined status, the content is displayed as a foreground to a top-level user interface of the mobile handheld device.

In a method for cleaning an anilox inking unit, a doctor bears against a roller and an intermediate roller bears against the roller and on an engraved roller. During cleaning, the intermediate roller has been or is displaced axially. Because the intermediate roller can be displaced axially, edge regions of the engraved roller can also be cleaned during a cleaning operation.

An air intake silencer assembly at the intake of an air handling system includes a plenum housing having an inlet end for receiving air and having an outlet port for discharging air. Two baffle panels in spaced relation in the housing define, with the housing, an inlet chamber, a central chamber, and a discharge chamber. A plurality of tubular members is supported by the baffle panels and each includes a perforated core and a sound dissipating fiber wrapping. Air flows into the inlet chamber, through the plurality of tubular members to the discharge chamber, and is discharged from the discharge chamber through the outlet port.
摘要:
A method for preparing an electrode for a solid oxide fuel cell, in which a conductive material, such as a metal, is electrodeposited onto a porous electrode comprising a conductive material and an electrolyte. The method allows metals to be added directly to a porous electrode without the need for subsequent reduction steps. The method also permits the conductive materials to be deposited in controlled, layered structures, thereby enabling the use of different metals to achieve desired properties.
