Patent number: 10763338Abstract: The present disclosure describes a silicide formation process which employs the formation of an amorphous layer in the SiGe S/D region via an application of a substrate bias voltage during a metal deposition process. For example, the method includes a substrate with a gate structure disposed thereon and a source/drain region adjacent to the gate structure. A dielectric is formed over the gate structure and the source-drain region. A contact opening is formed in the dielectric to expose a portion of the gate structure and a portion of the source/drain region. An amorphous layer is formed in the exposed portion of the source/drain region with a thickness and a composition which is based on an adjustable bias voltage applied to the substrate. Further, an anneal is performed to form a silicide on the source/drain region.Type: GrantFiled: August 30, 2017Date of Patent: September 1, 2020Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chia-Yang Wu, Shiu-Ko Jang-Jian, Ting-Chun Wang, Chuan-Pu Liu

Patent number: 10685122Abstract: A computer-implemented method for protecting a kernel for secure boot of an operating system includes preparing a kernel component with a signature for a secure boot. A processing unit modifies a machine owner key (MOK) file to include a trusted certificate. The MOK is separate from the kernel file. The processing unit validates the kernel component using a modified Grub file, a modified Shim file, and the MOK, and executes a secure boot using the validated kernel component. The kernel is unchanged by the secure boot process. The kernel component that is protected may be either a program executable (PE) file or a non-PE file.Type: GrantFiled: November 14, 2017Date of Patent: June 16, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Pu Liu, Timothy V.
