  • Patent number: 11983370
    Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.

  • Publication number: 20240134410
    Abstract: The present disclosure discloses a memory access interface device. A clock generation circuit generates reference signals. A transmitter transmits an output command and address signal to a memory device according to the reference signals. A signal training circuit executes a training process in a training mode that includes steps outlined below. A training signal is generated such that the training signal is transmitted as the output command and address signal. The training signal and the data signal generated by the memory device are compared to generate a comparison result indicating whether the data signal matches the training signal. The comparison result is stored. The clock generation circuit is controlled to modify a phase of at least one of the reference signals to be one of a plurality of under-test phases to execute a new loop of the training process until all the under-test phases are trained.

    Abstract: The present disclosure discloses a memory access interface device. A clock generation circuit generates reference clock signals. Each of access signal transmission circuits each includes a duty cycle adjusting circuit, a duty cycle detection circuit, a frequency division circuit and an asynchronous first-in-first-out circuit. The duty cycle adjusting circuit performs duty cycle adjustment on one of the reference clock signals according to a duty cycle detection signal to generate an output clock signal having a duty cycle. The duty cycle detection circuit detects a variation of the duty cycle to generate the duty cycle detection signal. The frequency division circuit divides a frequency of the output clock signal to generate a read clock signal. The asynchronous first-in-first-out circuit receives an access signal from a memory access controller and outputs an output access signal according to the read clock signal to access the memory device accordingly.

    Abstract: The present application discloses a semiconductor structure and methods for manufacturing semiconductor structures. The semiconductor structure includes a plurality of bottom dies and a top die stacked on the bottom dies. The bottom dies receive power supplies through tiny through silicon vias (TSVs) formed in backside substrates of the bottom dies, while the top die receives power supplies through dielectric vias (TDVs) formed in a dielectric layer that covers the bottom dies. By enabling backside power delivery to the bottom die, more space can be provided for trace routing between stacked dies. Therefore, greater computation capability can be achieved within a smaller chip area with less power loss.
