  • Publication number: 20200004155
    Abstract: Disclosed are embodiments of a multi-layer stack and photolithography methods and systems that employ such a stack. The disclosed multi-layer stacks include a photoresist layer on an underlayer. The photoresist layer and underlayer are made of different materials, which are selected so that valence and conduction band offsets between the underlayer and photoresist layer create an effective electric field (i.e., so that the stack is “self-biased”). When areas of the photoresist layer are exposed to radiation during photolithography and the radiation passes through photoresist layer and excites electrons in the underlayer, this effective electric field facilitates movement of the radiation-excited electrons from the underlayer into the radiation-exposed areas of the photoresist layer in a direction normal to the interface between the underlayer and the photoresist layer.

  • Publication number: 20190307504
    Abstract: An electrophysiology catheter (100) includes a catheter distal portion (110) on which a force sensor (200) is arranged. The force sensor (200) includes an elastic tube (210) and strain gauges (220). The elastic tube (210) has a hollow portion in its wall, and the strain gauges (220) are disposed external to the hollow portion. Compared to the design with the strain gauges (220) overlapping the hollow portion, arranging them over solid portions of the elastic tube (210) allows the strain gauges (220) to collect more accurate electrical signals while suffering from less interference. This can result in a significant improvement in contact force measurement accuracy of the catheter distal portion (110).
