  • Publication number: 20240134287
    Abstract: Embodiments of the present disclosure generally relate to lithography systems. More particularly, embodiments of the present disclosure relate to a method, a system, and a software application for a lithography process to control transmittance rate of write beams and write gray tone patterns in a single exposure operation. In one embodiment, a plurality of shots are provided by an image projection system in a lithography system to a photoresist layer. The plurality of shots exposes the photoresist layer to an intensity of light emitted from the image projection system. The local transmittance rate of the plurality of shots within an exposure area is varied to form varying step heights in the exposure area of the photoresist layer.

  • Patent number: 9269591
    Abstract: The present disclosure relates to a silicon-on-insulator (SOI) substrate having a trap-rich layer, with crystal defects, which is disposed within a handle wafer, and an associated method of formation. In some embodiments, the SOI substrate has a handle wafer. A trap-rich layer, having a plurality of crystal defects that act to trap carriers, is disposed within the handle wafer at a position abutting a top surface of the handle wafer. An insulating layer is disposed onto the handle wafer. The insulating layer has a first side abutting the top surface of the handle wafer and an opposing second side abutting a thin layer of active silicon. By forming the trap-rich layer within the handle wafer, fabrication costs associated with depositing a trap-rich material (e.g., polysilicon) onto a handle wafer are reduced and thermal instability issues are prevented.

  • Publication number: 20140183021
    Abstract: A float switch device includes a tubular member, a magnet tube and a magnetic switch. The tubular member has a first restriction portion and a second restriction portion formed on an external surface thereof. The magnet tube is sleeved over the tubular member, and is movable between the first restriction portion and the second restriction portion. The magnetic switch includes at least two metal tongues, where each of the metal tongues includes an interior contact point and an exterior contact point. The float switch device is placed in a casing in such way that the exterior contact points are electrically connected to an external apparatus. When the casing is tilted upward or downward by the change in water level, the magnet tube moves between the first and second restriction portions to switch the float switch device between the ON/OFF state.
