  • Patent number: 12222654
    Abstract: A method includes illuminating radiation to a resist layer over a substrate to pattern the resist layer. The patterned resist layer is developed by using a positive tone developer. The patterned resist layer is rinsed using a basic aqueous rinse solution. A pH value of the basic aqueous rinse solution is lower than a pH value of the developer, and a rinse temperature of rinsing the patterned resist layer is in a range of about 20° C. to about 40° C.

  • Patent number: 12211698
    Abstract: Provided is a material composition and method that includes forming a patterned resist layer on a substrate, where the patterned resist layer has a first line width roughness. In various embodiments, the patterned resist layer is coated with a treatment material, where a first portion of the treatment material bonds to surfaces of the patterned resist layer. In some embodiments, a second portion of the treatment material (e.g., not bonded to surfaces of the patterned resist layer) is removed, thereby providing a treated patterned resist layer, where the treated patterned resist layer has a second line width roughness less than the first line width roughness.

  • Patent number: 8108598
    Abstract: A hard drive assessing method and a hard drive assessing system supporting a maximum transmission rate of a hard drive are provided, wherein the hard drive is accessed by a controller, and both the controller and the hard drive support a plurality of transmission rates. The maximum transmission rate of the hard drive is first obtained. When the controller reads data from the hard drive, the transmission rate of the controller is set to be not lower than the maximum transmission rate, and the transmission rate of the hard drive is maintained at the maximum transmission rate. When the controller writes data into the hard drive, the transmission rate of the controller is reduced to be lower than the maximum transmission rate, and the transmission rate of the hard drive is maintained at the maximum transmission rate. Thereby, the hard drive can be accessed at its maximum transmission rate.

  • Patent number: 8051319
    Abstract: The invention provides a method for power management for a computer system. In one embodiment, the computer system comprises a system controller, a chipset, and a battery coupled to the chipset via a system management bus. First, a timer of the chipset is used to calculate an accumulated time value. When the accumulated time value exceeds a threshold value, the chipset is directed to send a system control interrupt to the system controller. After the system controller receives the system control interrupt, the system controller is triggered to detect a power level supplied by the battery via the system management bus.

  • Publication number: 20100199022
    Abstract: An information access method and a computer system are provided. The computer system includes a system management bus (SMBus), a non-volatile memory, a plurality of hardware devices, a chipset, and a CPU. The hardware devices have a plurality of specific recognition information. The CPU performs a configuration process on the hardware devices through the chipset according to the standard for a SMBus protocol, so as to distribute a plurality of memory spaces in the non-volatile memory to the hardware devices. The hardware devices share the SMBus for accessing the plurality of specific recognition information in the memory spaces.
