Abstract: A method for forming a semiconductor device structure is provided. The method includes forming a first source/drain structure and a second source/drain structure over and in a substrate. The method includes forming a first gate stack, a second gate stack, a third gate stack, and a fourth gate stack over the substrate. Each of the first gate stack or the second gate stack is wider than each of the third gate stack or the fourth gate stack. The method includes forming a first contact structure and a second contact structure over the first source/drain structure and the second source/drain structure respectively. A first average width of the first contact structure is substantially equal to a second average width of the second contact structure.

Abstract: A semiconductor package including a first semiconductor die, a second semiconductor die, a first insulating encapsulation, a dielectric layer structure, a conductor structure and a second insulating encapsulation is provided. The first semiconductor die includes a first semiconductor substrate and a through silicon via (TSV) extending from a first side to a second side of the semiconductor substrate. The second semiconductor die is disposed on the first side of the semiconductor substrate. The first insulating encapsulation on the second semiconductor die encapsulates the first semiconductor die. A terminal of the TSV is coplanar with a surface of the first insulating encapsulation. The dielectric layer structure covers the first semiconductor die and the first insulating encapsulation. The conductor structure extends through the dielectric layer structure and contacts with the through silicon via.

Abstract: A supported metallocene catalyst includes a carrier and a metallocene component. The carrier includes an inorganic oxide particle and an alkyl aluminoxane material. The inorganic oxide particle includes at least one inorganic oxide compound selected from the group consisting of an oxide of Group 3A and an oxide of Group 4A. The alkyl aluminoxane material includes an alkyl aluminoxane compound and an alkyl aluminum compound that is present in amount ranging from greater than 0.01 wt % to less than 14 wt % base on 100 wt % of the alkyl aluminoxane material. The metallocene component is supported on the carrier, and includes one of a metallocene compound containing a metal from Group 3B, a metallocene compound containing a metal from Group 4B, and a combination thereof. A method for preparing the supported metallocene catalyst and a method for preparing polyolefin using the supported metallocene catalyst are also disclosed.

Abstract: A hybrid cloud file system enabling a cloud storage volume with a cache storage utilizing local storage media is provided. Files in the hybrid cloud file system are substantially uploaded and stored into a cloud storage server and presented as no difference as storing in a local storage volume. Portion of the local storage media may be allocated as a cache storage storing files to be accessed locally for accelerate data fetching and processing. Besides uploading, fetching and deleting, deduplication mechanism before uploading and prefetch mechanism during/before data fetch are also provided in the present disclosure.

Abstract: The present disclosure includes a detection method for files infected by malware, especially ransomware, and an anti-malware system implemented with the method during file transmission, especially for backup or synchronization. Applying the detection method in the present disclosure before file transmission may prevent infection spreading by replace uninfected files with infected files. In one embodiment, the method includes: creating files as “baits” for being accessed by ransomware; and detecting whether files being to be transmitted due to updates including the “baits”. The present disclosure also includes file recovery method while finding malware infection by the detection method of in the present disclosure.
