Abstract:
A trench schottky diode which includes a thin insulation layer on the sidewalls of its trenches and a relatively thicker insulation layer at the bottoms of its trenches.
Abstract:
A Merged P-i-N Schottky device in which the oppositely doped diffusions extend to a depth and have been spaced apart such that the device is capable of absorbing a reverse avalanche energy comparable to a Fast Recovery Epitaxial Diode having a comparatively deeper oppositely doped diffusion region.
Abstract:
A fabrication process for a Schottky barrier structure includes forming a nitride layer directly on a surface of an epitaxial (“epi”) layer and subsequently forming a plurality of trenches in the epi layer. The interior walls of the trenches are then deposited with a final oxide layer without forming a sacrificial oxide layer to avoid formation of a beak bird at the tops of the interior trench walls. A termination trench is etched in the same process step for forming the plurality of trenches in the active area.
Abstract:
In accordance with an embodiment of the present invention, a semiconductor module includes a first semiconductor device having a first plurality of leads including a first gate/base lead, a first drain/collector lead, and a first source/emitter lead. The module further includes a second semiconductor device and a circuit board. The second semiconductor device has a second plurality of leads including a second gate/base lead, a second drain/collector lead, and a second source/emitter lead. The circuit board has a plurality of mounting holes, wherein each of the first plurality of leads and the second plurality of leads is mounted into a respective one of the plurality of mounting holes. At the plurality of mounting holes, a first distance from the first gate/base lead to the second gate/base lead is different from a second distance from the first source/emitter lead to the second source/emitter lead.
Abstract:
An IGBT for controlling the application of power to a plasma display panel has an increased current conduction capability and a reduced conduction loss at the expense of a reduced safe operating area. For a device with a 300 volt breakdown voltage rating, the die has a substrate resistivity less than 10 m ohm cm; a buffer layer thickness of about 8 μm resistivity in the range of 0.05 to 0.10 ohm cm, and an epi layer for receiving junction patterns and trenches, which has a thickness of from 31 to 37 μm and resistivity in te range of 14 to 18 ohm cm.
Abstract:
