Abstract: A semiconductor device structure is provided. The semiconductor device structure includes a substrate and a first dielectric layer over the substrate. The semiconductor device structure also includes a first metal gate stack and a second metal gate stack over the substrate and the first dielectric layer. The semiconductor device structure further includes a second dielectric layer beside the first metal gate stack and an insulating structure over the substrate. A portion of the insulating structure is between the first metal gate stack and the second metal gate stack. The insulating structure penetrates into the second dielectric layer.

Abstract: A method includes loading a wafer over a wafer chuck in a process chamber; performing a deposition process on the loaded wafer; supplying a fluid medium to a fluid guiding structure in the wafer chuck from a fluid inlet port on the wafer chuck, the fluid guiding structure comprising a plurality of arc-shaped channels fluidly communicated with each other; guiding the fluid medium from a first one of the arc-shaped channels of the fluid guiding structure to a second one of the arc-shaped channels of the fluid guiding structure. The second one of the arc-shaped channels of the fluid guiding structure is concentric with the first one of the arc-shaped channels of the fluid guiding structure from a top view.

Abstract: A system includes a mobile unit, road and procedure pieces, and a controller on the mobile unit that includes an optical sensor, a storage storing instructions and identification lookup tables, and a processor connected to the optical sensor and the storage. The optical sensor scans recognition patterns on the procedure pieces and identification patterns on the road pieces to correspondingly obtain recognition and identification codes. The processor controls the mobile unit to perform actions based on a collection of instructions generated according to the recognition codes and the instruction lookup table and based on entries of coordinate information obtained according to the identification codes and the identification lookup table.

Abstract: A memory management method and a storage controller are provided. The memory management method includes: dividing a plurality of word lines of a first block into a plurality of word line groups and recording a characteristic value for each of the word line groups; accumulating the characteristic values of a second word line group and a third word line group when reading a first word line group, wherein the second word line group and the third word line group are directly adjacent to the first word line group; and reading the second word line group via a first optimal read voltage group when the characteristic value of the second word line group is greater than a first threshold, wherein the first optimal read voltage group is different from a default read voltage group corresponding to the second word line group.

Abstract: A cosmetic case mirror assembly positioning device includes a mirror frame holder having two spaced lugs raised from one side of an elongate base plate fastened to the top cover of a cosmetic case on the inside, and a mirror frame having two lugs respectively pivoted to either lug on the mirror frame holder and two toothed supports respectively and releasably meshed with the toothed top edge of either lug on the mirror frame holder, and a mirror inserted into a channel on the mirror frame and locked in place by latch pins.
