Latest Patents

One of his latest patents is a method for exposing a semiconductor wafer. This method compensates for the effects of process inhomogeneities, such as those encountered in semiconductor etching or deposition processes. By individually adjusting sets of exposure parameters for any exposure field, the method enhances the precision of semiconductor manufacturing. The exposure parameters, which include the dose and focus, are varied across the semiconductor wafer to achieve optimal results.

Another significant patent by Torsten Seidel is a method for adjusting temperature in a resist process. This innovation involves a test reticle with pad and antenna structures that have varying critical dimensions. It is designed to measure sidewall angles developing in the resist sidewalls of clear lines. These angles can result from resist flow due to excessively high temperatures during the resist process on a lithographic track after the exposure of a semiconductor wafer. A scanning electron microscope is utilized for measurement, and a sequence of temperatures is applied in each postbake step to process the wafer. If a threshold value of a sidewall angle is exceeded, an error signal is issued, prompting an adjustment of the resist process temperature.
