  • Publication number: 20250118555
    Abstract: A method of processing a substrate includes forming a photoresist layer over the substrate, exposing the substrate to a pattern of an actinic radiation, where the exposing causes a photo-reaction in an exposed portion of the photoresist layer. The method includes treating the photoresist layer with a binding agent, where the binding agent is selectively adsorbed on a first portion of the photoresist layer, and performing a development process to remove a second portion of the photoresist, the first portion remaining after the development process.

  • Publication number: 20250076757
    Abstract: A method for fabricating a semiconductor device with organometallic based photoresists and commercial extreme ultraviolet photolithography. The method for fabricating a semiconductor device includes applying organometallic based photoresist to a substrate and exposing the organometallic based photoresist to extreme ultraviolet photolithography. The method may include introducing an additive to the organometallic based photoresist to promote at least one of adhesion, passivation, reactivity and cross-linking of components in the organometallic based photoresist. The method may also include exposing the organometallic based photoresist to microwave radiation. The microwave radiation may couple with molecular motions, such as internal rotations, to enhance organometallic based photoresist cluster mobility or reorientations. In addition, microwave radiation may induce charge polarization and eddy currents in materials, resulting in induced electron transport and heating due to resistive losses.

  • Patent number: 12181876
    Abstract: The present teaching relates to method, system, medium, and implementations for sensor calibration. An ego vehicle determines whether a sensor deployed on the ego vehicle to facilitate autonomous driving of the ego vehicle needs to be calibrated and sends, if it is determined that the sensor needs to be calibrated, a request for assistance in collaborative calibration of the sensor, with a first position of the ego vehicle or a first configuration of the sensor with respect to the ego vehicle. When a response of the request is received, an assisting vehicle is indicated to travel to be near the ego vehicle to facilitate the calibration of the sensor by collaborating with the moving ego vehicle and the ego vehicle coordinates with the assisting vehicle to enable the sensor to acquire information of a target present on the assisting vehicle for the collaborative calibration of the sensor.

  • Publication number: 20240421009
    Abstract: Embodiments of processing systems and methods are provided to control operational parameter(s) of a spin-on process based on a fluid height and/or a fluid velocity of a processing liquid dispensed onto a surface of a spinning semiconductor substrate. The disclosed embodiments determine the fluid height and/or the fluid velocity of the processing liquid by: (a) monitoring an intensity of light, which is transmitted through the processing liquid as the processing liquid flows across the surface of the spinning substrate or leaves the periphery of the spinning substrate, or (b) monitoring how long it takes for the processing liquid to flow from a dispensed location to the periphery of the spinning substrate. Once determined, the fluid velocity is used to control one or more operational parameters of a spin-on process.

  • Publication number: 20240420973
    Abstract: Systems and methods are provided to control operational parameter(s) of a spin-on process based on a localized fluid velocity of a processing liquid dispensed onto a surface of a spinning semiconductor substrate. In the present disclosure, a tracer is introduced within, or incorporated onto a surface of, a processing liquid as the processing liquid is dispensed onto the spinning semiconductor substrate. Movement of the tracer is tracked over time, as the tracer flows along with the processing liquid across the spinning substrate surface, to determine a localized fluid velocity of the processing liquid at one or more radial positions on the substrate surface. The localized fluid velocity is then used to control one or more operational parameters of a spin-on process.

  • Publication number: 20240331258
    Abstract: In implementation of techniques for generating video from an image based on variable speed, a computing device implements a variable speed system to receive a static digital image displayed in a user interface, an indication of a movement direction, and an indication of a variable rate of speed. The variable speed system generates a digital video based on the static digital image, the digital video having pixels that move in the movement direction at a speed that varies based on the variable rate of speed based on pixels from the static digital image. The variable speed system then displays the digital video in the user interface.

  • Publication number: 20240061126
    Abstract: The present teaching relates to method, system, medium, and implementations for sensor calibration. An ego vehicle determines whether a sensor deployed thereon to facilitate autonomous driving needs to be calibrated and sends, if it is determined that the sensor needs to be calibrated, a request for assistance in collaborative calibration of the sensor to a center. The request includes at least a first position of the ego vehicle on the route and a first configuration of the sensor with respect to the ego vehicle. When the ego vehicle receives a calibration assistant package, which includes information associated with a collaborative means present along the route and to be used to assist the ego vehicle to calibrate the sensor, it identifies, based on the information, the collaborative means along the route when the ego vehicle is in a vicinity of the collaborative means in order to capture a target present on the collaborative means to enable calibration of the sensor.
