Title: Clemens Utzny: Innovator in Photomask Technology

Introduction

Clemens Utzny is a notable inventor based in Dresden, Germany. He has made significant contributions to the field of photomask technology, holding 2 patents that showcase his innovative approach to manufacturing and metrology.

Latest Patents

One of his latest patents is titled "Shape metrology for photomasks." This invention involves a method of manufacturing a photomask that includes forming a mask pattern with a critical mask feature. The method obtains shape information that describes the outline of the critical mask feature, including position information that identifies the positions of landmarks on the outline relative to each other. This shape information enables a metrology process that is not solely based on rectangular approximations of mask features.

Another significant patent is "EUV mask set and methods of manufacturing EUV masks and integrated circuits." This patent discloses a method for inspecting a set of EUV mask blanks to obtain information about defects. From this information, complementary functional portions are determined, which do not contain any defects. The functional portions complement one another to form a virtual image area corresponding to the image areas of the EUV mask blanks, allowing for precise control of the illumination process for imaging predefined mask patterns onto a target.
