摘要:
A semiconductor device with a dielectric layer is produced by providing a semiconductor body with a first trench extending into the semiconductor body, the first trench having a bottom and a sidewall. A first dielectric layer is formed on the sidewall in a lower portion of the first trench and a first plug is formed in the lower portion of the first trench so as to cover the first dielectric layer. The first plug leaves an upper portion of the sidewall uncovered. A sacrificial layer is formed on the sidewall in the upper portion of the first trench and a second plug is formed in the upper portion of the first trench. The sacrificial layer is removed so as to form a second trench having sidewalls and a bottom. A second dielectric layer is formed in the second trench and extends to the first dielectric layer.
