Abstract(J)	電動機駆動用インバータに用いるパワー半導体デバイスの性能向上のために、SBD内蔵SiC-MOSFETのデバイス構造の改善を検討した。内蔵SBDの配置パターンの改良によって、ダイオード動作に対する信頼性を向上した。さらに、必要なSBD搭載面積が縮小したことでMOSFETの面積比率が増加し、オン抵抗の低減を同時に実現した。 Translation
Abstract(E)	To improve the performance of power semiconductor devices for motor drive inverters, we investigated the device structure of SiC-MOSFET with embedded SBD. The reliability of diode operation was improved by the developed layout pattern of the embedded SBD. Furthermore, the increased MOSFET area ratio by smaller SBD area consumption realized on-resistance reduction.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
