Abstract: Embodiments provide a method of performing a carrier switch for a device wafer, attaching a second wafer and removing a first wafer. A buffer layer is deposited over the device wafer, buffer layer reducing the topography of the surface of the device wafer. After the carrier switch a film-on-wire layer is removed from the buffer layer and then the buffer layer is at least in part removed.

Abstract: A flexible tube includes a first connecting portion and a second connecting section. The second connecting section and the first connecting section are integrally connected to each other. The first connecting section has a first end surface, and the second connecting section has a second end surface, wherein there is an acute angle between the first end surface and the second end surface.

Abstract: A leak check is performed on a semiconductor wafer processing tool that includes a process chamber and process gas lines, and a semiconductor wafer is processed using the semiconductor wafer processing tool if the leak check passes. Each gas line includes a mass flow controller (MFC) and normally closed valves including an upstream and downstream valves upstream and downstream of the MFC. Leak checking includes: leak checking up to the downstream valves of the gas lines with the upstream valves closed and the downstream valves of the gas lines closed; and leak checking up to the upstream valve of each the process gas line with the upstream valves of the of the process gas lines closed and with the downstream valve of the of the process gas line being leak checked open and the downstream valve of every other process gas line closed.

Abstract: A bonding tool includes a gas supply line that may extend directly between valves associated with one or more gas supply tanks and a processing chamber such that gas supply line is uninterrupted without any intervening valves or other types of structures that might otherwise cause a pressure buildup in the gas supply line between the processing chamber and the valves associated with the one or more gas supply tanks. The pressure in the gas supply line may be maintained at or near the pressure in the processing chamber so that gas provided to the processing chamber through the gas supply line does not cause a pressure imbalance in the processing chamber, which might otherwise cause early or premature contact between semiconductor substrates that are to be bonded in the processing chamber.

Abstract: A first polymer layer is formed across a package region and a test region. A first metal pattern is formed in the package region and a first test pattern is simultaneously formed in the test region. The first metal pattern has an upper portion located on the first polymer layer and a lower portion penetrating through the first polymer layer, and the first test pattern is located on the first polymer layer and has a first opening exposing the first polymer layer. A second polymer layer is formed on the first metal pattern in the package region and a second test pattern is simultaneously formed on the first test pattern in the test region. The second polymer layer has a second opening exposing the upper portion of the first metal pattern, and the second test pattern has a third opening greater than the first opening of the first test pattern.

Abstract: Provided is a use of a regulator of ITPRIPL1 in the preparation of a drug that regulates immune responses or resists tumors, the regulator being used to increase or decrease the expression or function of the ITPRIPL1 gene or protein in an organism. Also provided is a pharmaceutical composition, which comprises the regulator used in the use. Also provided are an isolated ITPRIPL1 recombinant protein and an antibody that recognizes and binds to the ITPRIPL1. On the basis of the principle that an ITPRIPL1 protein binds to CD3? and NRP2 receptors to regulate the functions of different immune cells, and then participates in the regulation of immune responses and a process of immune evasion of a tumor, it is confirmed that a regulator of ITPRIPL1 may be used to prepare a drug or a pharmaceutical composition, and may be applied to suppress tumors, autoimmune disease, transplant rejection, allergies and infections and other diseases.

Abstract: Methods for forming patterned multi-layer stacks including a metal-containing layer are provided herein. Methods involve using silicon-containing non-metal materials in a multi-layer stack including one sacrificial layer to be later removed and replaced with metal while maintaining etch contrast to pattern the multi-layer stack and selectively remove the sacrificial layer prior to depositing metal. Methods involve using silicon oxycarbide in lieu of silicon nitride, and a sacrificial non-metal material in lieu of a metal-containing layer, to fabricate the multi-layer stack, pattern the multi-layer stack, selectively remove the sacrificial non-metal material to leave spaces in the stack, and deposit metal-containing material into the spaces. Sacrificial non-metal materials include silicon nitride and doped polysilicon, such as boron-doped silicon.

Abstract: A virtual reality (VR) system supports improved interactive control processes/services. These interactive control processes/services include detecting movement of a controller associated with a virtual reality (VR) environment, determining an angle of rotation based on the movement, determining a magnitude of force associated with the movement, determining a path in the VR environment that corresponds to the angle of rotation and the magnitude of force, and projecting the path in the VR environment.

Abstract: The present disclosure is directed towards having a user interface that displays a number of cards or windows. A user can implement a command where the user interface will automatically change the position of the displayed cards to show regions of interest which are the parts of the cards that a user may have interested in. The user interest can be determined in accordance with user preference information. Optionally, cards which do not have regions of interest are removed from a display area and such cards are replaced with new cards that do have regions of interest.
