  • Patent number: 11551938
    Abstract: Tin oxide films are used as spacers and hardmasks in semiconductor device manufacturing. In one method, tin oxide layer (e.g., spacer footing) needs to be selectively etched in a presence of an exposed silicon-containing layer, such as SiOC, SiON, SiONC, amorphous silicon, SiC, or SiN. In order to reduce damage to the silicon-containing layer the process involves passivating the silicon-containing layer towards a tin oxide etch chemistry, etching the tin oxide, and repeating passivation and etch in an alternating fashion. For example, passivation and etch can be each performed between 2-50 times. In one implementation, passivation is performed by treating the substrate with an oxygen-containing reactant, activated in a plasma, and the tin oxide etching is performed by a chlorine-based chemistry, such as using a mixture of Cl2 and BCl3.

  • Patent number: 11482015
    Abstract: A method for recognizing a parking space for a vehicle and a parking assistance system are disclosed. An obstacle is identified from successive image frames captured when the vehicle is moving and a first boundary for the obstacle is generated by a Convolutional Neural Network (CNN) algorithm based on a position of the obstacle shown in each of the successive image frames. Distances between the moving vehicle and the obstacle are detected by ultrasonic sensors. A second boundary for the obstacle is generated by a distance modification module based on the distances between the vehicle and the obstacle. A periphery of the obstacle is defined by a periphery definition module. In view of the periphery of the obstacle, a parking space is thus recognized by a parking space recognition module. The parking process can be changed to a self-drive mode, and remotely controlled by a mobile device.

  • Publication number: 20220335331
    Abstract: A method for behavior vectorization of information de-identification, through which data concerning browsing traces, link paths, trigger events, clicks, and operation behaviors of network users on the Internet are selected by a server, a client device, or an edge device for performing a conversion/integration process. Then, the integrated data are converted into a vector. The vector represents the profile of the usage behavior of the network users. Moreover, because vectors can be quickly grouped and classified to find similar groups, it can quickly identify the network users. The server uses the supervised learning method as the base method, and uses pre-defined network behaviors for training. Also, the semi-supervised learning method or the unsupervised learning method can be employed to modify undefined network behaviors to better conform to the profile description of the network users.

  • Patent number: 11477420
    Abstract: The disclosure provides an illumination system and a projection device applying the illumination system. The illumination system includes a laser light source, a wavelength conversion module, and a spot region modulation module configured to shift a transmission path of a laser beam. When the wavelength conversion module rotates, the spot region modulation module moves, in a first period of time, the laser beam in a wavelength conversion region of the wavelength conversion module along a first shift path, so that the laser beam forms a first spot region in an irradiation region in the wavelength conversion region. The spot region modulation module causes, in a second period of time, the laser beam to form a second spot region in an irradiation region in a non-conversion region of the wavelength conversion module. A size of the first spot region is greater than a size of the second spot region.
