Latest Patents

“Integrated Circuits with an Insulating Layer and Methods for Producing Such Integrated Circuits” describes forming a porous insulating material from a silicon-oxide composition containing a porogen. After removing the porogen, the resulting material has a lower dielectric constant. The method then adjusts the material’s composition so its mechanical properties fall within a desired range.

“Semiconductor Device Comprising Metallization Layers of Reduced Interlayer Capacitance by Reducing the Amount of Etch Stop Materials” addresses parasitic capacitance between metal lines in adjacent metallization layers. It uses patterned etch-stop material to support reliable via formation while reducing the metallization system’s overall dielectric constant and capacitance between stacked metal lines.

Career Highlights

Pfutzner’s listed patent work concerns two important aspects of semiconductor design: tailoring insulating-layer properties and improving the electrical performance of complex metallization systems. Both inventions seek to balance manufacturing reliability with device performance.

Collaborations

Pfutzner is associated with GlobalFoundries Inc. His named coworkers include Jens Heinrich and Andreia Ioana Popa.
