  • Patent number: 12218160
    Abstract: A pixel sensor may include a layer stack to reduce and/or block the effects of plasma and etching on a photodiode and/or other lower-level layers. The layer stack may include a first oxide layer, a layer having a band gap that is approximately less than 8.8 electron-Volts (eV), and a second oxide layer. The layer stack may reduce and/or prevent the penetration and absorption of ultraviolet photons resulting from the plasma and etching processes, which may otherwise cause the formation of electron-hole pairs in the substrate in which the photodiode is included.

  • Publication number: 20250022938
    Abstract: One aspect of the present disclosure pertains to a method of forming a semiconductor structure. The method includes forming an active region over a substrate, forming a dummy gate layer over the active region, forming a hard mask layer over the dummy gate layer, forming a patterned photoresist over the hard mask layer, and performing an etching process to the hard mask layer and the dummy gate layer using the patterned photoresist, thereby forming patterned hard mask structures and patterned dummy gate structures. The patterned hard mask structures are formed with an uneven profile having a protruding portion. The protruding portion of each of the patterned hard mask structures has a first width, wherein each of the patterned dummy gate structures has a second width, and the first width is greater than the second width.

  • Patent number: 11834867
    Abstract: An anti-theft lock includes an engaging member arranged on a chassis, a latch module including a connecting member and a latch coupled to the connecting member, a fixing module coupled to the connecting member, a magnetic module arranged on the top cover and used to cooperate with the fixing module to control movement of the connecting member, and an unlocking mechanism including magnetic members. The connecting member is movably arranged on a top cover. The latch is engaged with or separated from the engaging member through movement of the connecting member. The magnetic members are attracted to or repelled from the magnetic module so that the magnetic module fixes or loosens the connecting member. When the connecting member can move, the latch is disengaged from and separated from the engaging member.

  • Patent number: 9177146
    Abstract: A database of known graphical user interface layouts is generated using samples of known executable files. An executable file having an unknown function is obtained; it is executed within a safe environment and its graphical user interface is identified. Layout analysis enumerates all of the windows within the interface and extracts the position values of each window and the dimension values of each window to form a set of layout information. If the layout database contains this layout information set then it is determined that the layout information is of the same type of software corresponding to the type of software contained within the database (or of the type of software to which the layout information is matched within the database). A match may occur if all the windows match, if only some percentage of the windows match, or if the windows do not match exactly but the dimensions of the corresponding window in the database are within a certain percentage.
