Patent number: 8647991Abstract: A method for forming a dual damascene opening includes the following steps. Firstly, a first hard mask layer with a trench pattern is formed over a material layer. Then, a dielectric layer is formed over the first hard mask layer and filled into an opening of the trench pattern. Then, a second hard mask layer with a via opening pattern is formed over the first hard mask layer and the dielectric layer. Then, a first etching process is performed, so that a via opening is at least formed in the dielectric layer. After the second hard mask layer is removed, a second etching process is performed. Consequently, a trench opening is formed in the material layer and the via opening is further extended into the material layer, wherein the via opening is located within the trench opening.Type: GrantFiled: July 30, 2012Date of Patent: February 11, 2014Assignee: United Microelectronics Corp.Inventors: Yu-Heng Liu, Seng-Wah Liau

Patent number: 8578477Abstract: The integrity of a computer may be checked by issuing a command to read data from a hardware component of the computer and retrieving the data from a data transfer buffer. The command may be sent to a secure driver that places the central processing unit (CPU) of the computer in system management mode to trigger execution of a system management interrupt (SMI) handler. The SMI handler may read the data from the hardware component, encrypt the data, and place the encrypted data in the data transfer buffer. A system integrity check application program may read the encrypted data to determine presence of malicious code based on the data. For example, the application program may infer presence of malicious code when the encrypted data does not conform to a particular encryption algorithm or when the data does not appear in the data transfer buffer.Type: GrantFiled: March 28, 2007Date of Patent: November 5, 2013Assignee: Trend Micro IncorporatedInventors: Yichin Lin, Peng-Yuan Yueh, Yu-Heng Liu
