  • Patent number: 8377318
    Abstract: A method for manufacturing a magnetic device that obtains sufficient processing accuracy without increasing mask removal steps. A first mask layer is formed above a magnetic layer using one selected from the group consisting of Ti, Ta, W, and an oxide or a nitride thereof. A second mask layer is formed on the first mask layer using Ru or Cr. A resist pattern is formed on the second mask layer. A second mask pattern is formed by performing reactive ion etching with reactive gas containing oxygen on the second mask layer using the resist pattern. A first mask pattern is formed by performing reactive ion etching with reactive gas containing halogen gas on the first mask layer using the second mask pattern. A magnetic pattern is formed by performing reactive ion etching with reactive gas containing oxygen on the magnetic layer using the first mask pattern.

  • Publication number: 20120327728
    Abstract: Memories containing command decoder, chip enable, and signal truncation circuits are disclosed. One such command decoder circuit may include command decoder logic configured to receive command signals and output a decoded command to an interconnect bus responsive to a chip select signal having an active state. Decoder circuits may also prevent coupling commands to the interconnect bus based on the receipt of chip select signals having inactive states. The memory further may include chip enable circuits having control logic configured to receive chip select signals and provide the chip select signals to an interconnect bus responsive to receiving a valid command. Chip enable circuits may also prevent coupling chip select signals to the interconnect bus from chip enable signals based on the receipt of invalid command signals. Signal truncation circuits may be used to shorten and/or shift chip select signals to increase timing margins and improve the reliability of command execution by memories.
