  • Patent number: 10008440
    Abstract: A carrier for an electrical component, including a substrate having a surface, with an electrically conductive contact zone arranged on the surface of the substrate, a solder pad disposed on the contact zone, and a solder stop structure disposed laterally next to the solder pad. The solder stop structure has a surface that is less wettable with liquid solder than a surface of the contact zone. The solder stop structure subdivides the contact zone into a first zone region and a second zone region, with the first zone region having the solder pad. The solder stop structure extends over a portion of a total length of the contact zone such that the contact zone has a free connecting region that is free of the solder stop structure. The first and second zone regions are connected to one another by means of the free connecting region.

  • Patent number: 7291569
    Abstract: Fluids for use in immersion lithography systems are disclosed. A resistivity-altering substance is introduced into a fluid, making it more conductive. The fluid is then disposed between an immersion head of a projection lens system and a semiconductor wafer during an exposure process. Because the fluid is conductive, electrostatic energy that may develop during the movement of the semiconductor wafer with respect to the projection lens system during the exposure process is discharged through the conductive fluid, preventing damage to an immersion head of the projection lens system, the semiconductor wafer, and sensors of a stage that supports the semiconductor wafer.
