<p>A method for filling gaps (1) on a semiconductor wafer (2) with a dielectric material (3, 8) employs a plasma enhanced chemical vapor deposition (PECVD) process with a temperature in the range of 500 to 700°C. As a result of deposition gaps for e.g. shallow trench isolation or premetal dielectric techniques are filled homogeneously without any voids. The deposition may be improved with the application of a second radio frequency signal.</p> |
