Abstract: An inkjet head unit capable of performing high-resolution pixel printing on a large-size substrate and a substrate treatment apparatus including the inkjet head unit are provided. The substrate treatment apparatus includes: a processing unit supporting and moving a substrate; an inkjet head unit performing pixel printing on the substrate; and a gantry unit moving the inkjet head unit over the substrate, wherein the inkjet head unit includes head packs, which include a plurality of nozzles ejecting a substrate treatment liquid onto the substrate, and a head base, in which the head packs are installed and the head packs are disposed in a single row in the head base.

Abstract: Proposed are an inkjet head unit capable of forming high-resolution pixels on a substrate and inkjet printing equipment including the same. An inkjet head unit of inkjet printing equipment according to one embodiment includes a head pack including a plurality of ejection heads configured to eject ink of the same color to a substrate; and a head base on which a plurality of head packs are installed to be repeatedly coaxially arranged in color order.

Abstract: The present invention relates to a trench cross-section reference line setting device, comprising: a trench reference line setting body unit (100) for setting a trench cross-section reference line, wherein the trench reference line setting body unit (100) has a sensor unit (10) at the center thereof, two horizontal units (20) orthogonal to each other on the upper surface thereof, and three laser light source units (30) and a grid photographing unit (110?), respectively, on the side surfaces thereof; a reference line setting tripod unit (200) rotatably coupled to the trench reference line setting body unit (100) and having a posture adjusting unit (230) and a height adjusting unit (250); and a trench stratum analysis server (300) for receiving a fault image photographed by the grid photographing unit (110?) of the trench reference line setting body unit (100) and creating a stratum map of a trench cross-section structure.

Abstract: Provided are a device and a system on chip. A device may include: a plurality of functional blocks comprising a slave block, a first master block, and second master block, wherein the first master block and second master block are configured to selectively access the slave block; a system bus configured to connect the plurality of functional blocks; an access information generator configured to store access setting information received from outside and, based on the access setting information, output access control information; and an access controller configured to, in response to the access control information, determine whether to permit an access from the first master block to the slave block.

Abstract: A method of operating a memory management unit includes accessing a translation lookaside buffer (TLB), translating a page number of a virtual address into a frame number of a physical address when there is a match for the page number of the virtual address in the TLB, executing a miss process when there is no match for the page number of the virtual address in the TLB. The miss process includes accessing a page table translation (PTT) cache, checking whether access information of a k-th level page table corresponding to a k-th page number that will be accessed in the virtual address is in the PTT cache, acquiring a base address of a physical page using the access information, and determining the frame number of physical address corresponding to the page number of the virtual address using a page offset in the physical page.
