    • A method, device and system for securely managing debugging processes within a communication device, such as a set top box or other multimedia processing device. For example, a security processor (SP) within the communication device manages the lifetime (LT) of any access token issued for use in activating debugging privileges within the communication device. The security processor authenticates an issued access token and securely delivers appropriate debug authorization information to the device controller. The security processor uses its secure, internal timer to count down the lifetime and update the remaining lifetime of the issued access token during the processing of each command by the security processor. In addition to securely managing the issuance of the access token and it's remaining lifetime, the updating process reduces any impact on the normal communications within the device. The method overcomes the issue of the communication device not having a secure internal clock.
    • 一种用于在诸如机顶盒或其他多媒体处理设备的通信设备内安全地管理调试过程的方法,设备和系统。 例如,通信设备内的安全处理器(SP)管理为在激活通信设备内的调试权限而被使用的任何访问令牌的寿命(LT)。 安全处理器对发出的访问令牌进行身份验证,并将安全的传递适当的调试授权信息提供给设备控制器。 安全处理器使用其安全的内部定时器来计数生命周期,并且在安全处理器处理每个命令期间更新发出的访问令牌的剩余生命周期。 除了安全地管理访问令牌的发行和剩余的生命周期外,更新过程减少了对设备内正常通信的任何影响。 该方法克服了没有安全内​​部时钟的通信设备的问题。

    • A partially completed semiconductor integrated circuit device. The device has a semiconductor substrate and a dielectric layer overlying the semiconductor substrate. The device has a gate structure including edges and a substantially pure silicon dioxide mask structure overlying the gate structure. A thickness ranging from about 400 to about 600 Angstroms of the substantially pure silicon dioxide mask structure is included. The device has a dielectric layer forming sidewall spacers on the edges of the gate structure to protect the gate structure including the edges and an exposed portion of the pure silicon dioxide mask structure overlying the gate structure. The device has an epitaxially grown fill material (e.g., silicon/germanium, silicon carbide) in an etched source region and an etched drain region. Preferably, the etched source region and the etched drain region are coupled to the gate structure. The device has a strained channel region between the filled source region and the filled drain region from at least the fill material formed in the etched source region and the etched drain region.
    • 部分完成的半导体集成电路器件。 该器件具有覆盖半导体衬底的半导体衬底和电介质层。 该器件具有包括边缘的栅极结构和覆盖栅极结构的基本上纯的二氧化硅掩模结构。 包括约400至约600埃基本上纯的二氧化硅掩模结构的厚度。 器件具有在栅极结构的边缘上形成侧壁间隔物的电介质层,以保护包括边缘的栅极结构和覆盖栅极结构的纯二氧化硅掩模结构的暴露部分。 该器件在蚀刻的源极区域和蚀刻的漏极区域中具有外延生长的填充材料(例如,硅/锗,碳化硅)。 优选地,蚀刻的源极区域和蚀刻的漏极区域耦合到栅极结构。 该装置在填充的源区和填充的漏极区之间具有至少从形成在蚀刻的源极区和蚀刻的漏极区中的填充材料的应变通道区。
