  • Patent number: 9177796
    Abstract: The embodiments herein provides methods for forming a PVD silicon oxide or silicon rich oxide, or PVD SiN or silicon rich SiN, or SiC or silicon rich SiC, or combination of the preceding including a variation which includes controlled doping of hydrogen into the compounds heretofore referred to as SiOxNyCz:Hw, where w, x, y, and z can vary in concentration from 0% to 100%, is produced as a hardmask with optical properties that are substantially matched to the photo-resists at the exposure wavelength. Thus making the hardmask optically planarized with respect to the photo-resist. This allows for multiple sequences of litho and etches in the hardmask while the photo-resist maintains essentially no optical topography or reflectivity variations.

  • Patent number: 9162930
    Abstract: The present invention generally relates to a doped aluminum nitride hardmask and a method of making a doped aluminum nitride hardmask. By adding a small amount of dopant, such as oxygen, when forming the aluminum nitride hardmask, the wet etch rate of the hardmask can be significantly reduced. Additionally, due to the presence of the dopant, the grain size of the hardmask is reduced compared to a non-doped aluminum nitride hardmask. The reduced grain size leads to smoother features in the hardmask which leads to more precise etching of the underlying layer when utilizing the hardmask.

  • Publication number: 20150278524
    Abstract: Firmware updates at an information handling system flash memory device, such as provisioning information stored on a USB device, are securely performed by using a buffer memory and a secured code. An application running on a CPU generates a firmware update and a security code, such as a ciphered hash code based on the firmware update, stores the firmware update and security code in a buffer, and informs a management processor of the update. The management processor analyzes the firmware update to authorize copying of the update from the buffer to the flash memory device. For instance, the management processor creates the security code from the firmware update and compares the created code with the security code stored in the buffer to validate the firmware update.

  • Patent number: 9092424
    Abstract: Described is a technology for understanding entities of a webpage, e.g., to label the entities on the webpage. An iterative and bidirectional framework processes a webpage, including a text understanding component (e.g., extended Semi-CRF model) that provides text segmentation features to a structure understanding component (e.g., extended HCRF model). The structure understanding component uses the text segmentation features and visual layout features of the webpage to identify a structure (e.g., labeled block). The text understanding component in turn uses the labeled block to further understand the text. The process continues iteratively until a similarity criterion is met, at which time the entities may be labeled. Also described is the use of multiple mentions of a set of text in the webpage to help in labeling an entity.
