  • Patent number: 9035382
    Abstract: One or more embodiments of techniques or systems for forming a semiconductor structure are provided herein. In some embodiments, a semiconductor structure includes a substrate, a first lightly doped drain (LDD), a second LDD, an interface layer (IL), a high-k stack, a gate region, a dummy poly region, a first hard mask (HM) region, a second HM region, and a seal spacer region. The HK stack has a HK stack width and the gate region has a gate region width that is less than or substantially equal to the HK stack width. Because of the increased width of the HK stack, some of the HK stack likely overlaps some of the first LDD or the second LDD. In this manner, a saturation current and a threshold voltage associated with the semiconductor structure are improved. The increased width of the HK stack also protects more of the IL during LDD implanting.

  • Publication number: 20150024518
    Abstract: The present disclosure relates to a method of forming a gate structure that can be selectively adjusted to reduce critical-dimension (CD) variations. In some embodiments, the method is performed by forming a gate structure having a first length over a semiconductor substrate. The first length of the gate structure is measured and compared to a target length. If the first length differs from the target length by an amount that is greater than a threshold value, the first length is adjusted to converge upon the target length. By selectively adjusting the length of the gate structure, critical-dimension (CD) variations can be reduced, thereby increasing yield and reducing cost.

  • Patent number: 8923088
    Abstract: A solid state storage device receives a device sleep signal and a power signal from a host. The solid state storage device includes a control chip, a sleep control circuit, and a regulator. If the device sleep signal is activated, the control chip temporarily stores a system parameter into a flash memory module and then generates an acknowledge signal. The sleep control circuit receives the power signal, the device sleep signal and the acknowledge signal. If both of the device sleep signal and the acknowledge signal are activated, the sleep control circuit generates a disable state and a wake-up state. Moreover, if the power signal is received by the regulator and the sleep control circuit generates the disable state, the regulator stops providing a supply voltage to the control chip, so that the solid state storage device enters a sleep mode.
