Insulation Structure Formed in a Semiconductor Substrate and Method for Forming an Insulation Structure |
摘要 |
A method for forming an insulation structure in a semiconductor body includes forming a trench extending from a first surface into a semiconductor body, the trench having a first width in a horizontal direction of the semiconductor body, and forming a void spaced apart from the first surface in a vertical direction of the semiconductor body, the void having a second width in a horizontal direction that is greater than the first width, wherein the trench and the void are arranged adjacent to each other in a vertical direction. |
