  • Publication number: 20250217254
    Abstract: A reinforcement learning-based system for adaptively controlling computing performance is provided. The system includes an environment module and an agent module. The environment module is configured to collect environment information from the application environment. Based on the collected environment information, the environment module calculates a reward value using a reward function and then outputs the state data and the reward value to the agent module. The agent module receives the output from the environment module, including the reward value and the state data. Based on the received reward value and state data, the agent module determines a performance adjustment action to take, which is then fed back to the application environment. Upon receiving the performance adjustment action, the application environment executes the performance adjustment operation in response, causing the environment module to collect the updated environment information as a result of the performance adjustment operation.

  • Publication number: 20250207865
    Abstract: A vapor chamber includes a vapor chamber body, multiple dendritic wick structures and a working fluid. The vapor chamber body includes a hollow shell and a capillary wick layer covered on an inner wall of the hollow shell. Each dendritic wick structure has a capillary base and multiple capillary braches. A side of the capillary base is sintered and connected to the capillary wick layer and another side has a convex curved portion. The multiple capillary branches are extended from and formed as one piece with the convex curved portion. The working fluid is filled in the hollow shell. Thereby, the multiple capillary branches and the convex curved portion can increase cooling surface area of the dendritic wick structure to make the vapor chamber and the dendritic wick structure have great cooling efficiency.

  • Publication number: 20250199412
    Abstract: A lithography method includes the following steps. A target layer is formed over a substrate. A photoresist composition is applied over the target layer to form a photoresist layer, wherein the photoresist composition comprises a metal-oxide based material. The photoresist layer is exposed to form an exposed region in the photoresist layer. A mixture is applied to the photoresist layer to develop the photoresist layer, wherein the step of applying the mixture to the photoresist layer increases a crosslinking density of the photoresist layer and increases a dissolution contrast of the photoresist layer during developing the photoresist layer by increasing a hydrophilicity of the exposed region. The target layer is etched using the photoresist layer as an etch mask.
