Title: Kay Viehweger - Innovator in Semiconductor Technology
Introduction: Kay Viehweger is an inventor based in Ortrand, Germany. He is associated with Forschungszentrum Jülich GmbH, where he contributes to advancements in semiconductor technology. Despite having no granted patents, his work in the field is noteworthy.
Latest Patent Applications: One of Kay Viehweger's significant patent applications is titled "Vertical Wiring of a Semiconductor Component." This application describes a semiconductor component that includes a semiconductor substrate, a first electrical insulation layer on a front side, a second electrical insulation layer on the first electrical insulation layer, and a contact surface for the semiconductor substrate in or on the second electrical insulation layer. The method for making a recess for a through contact involves creating a blind hole-like recess through the semiconductor substrate to the first electrical insulation layer, removing the first electrical insulation layer within the blind hole-like recess, and expanding the blind hole-like recess in a direction towards the contact surface by partially removing the second electrical insulation layer. Additionally, it includes applying a third electrical insulation layer to the inner walls of the expanded recess, ensuring that the first electrical insulation layer is covered up to the expanded recess, and anisotropic etching the second electrical insulation layer towards the contact surface until the contact surface for the semiconductor substrate is revealed.
Conclusion: Kay Viehweger's contributions to semiconductor technology through his innovative patent applications reflect his dedication to advancing the field. His work at Forschungszentrum Jülich GmbH showcases the importance of research and development in creating new technologies.
