Abstract: Methods and semiconductor devices are provided. A method includes determining a location of a polyimide opening (PIO) corresponding to an under-bump metallization (UBM) feature in a die. The die includes a substrate and an interconnect structure over the substrate. The method also includes determining a location of a stacked via structure in the interconnect structure based on the location of the PIO. The method further includes forming, in the interconnect structure, the stacked via structure comprising at most three stacked contact vias at the location of the PIO.

Abstract: A memory device, includes a memory array for storing a plurality of vector data each of which has an MSB vector and a LSB vector. The memory array includes a plurality of memory units each of which has a first bit and a second bit. The first bit is used to store the MSB vector of each vector data, the second bit is used to store the LSB vector of each vector data. A bit line corresponding to each vector data executes one time of bit-line-setup, and reads the MSB vector and the LSB vector of each vector data according to the bit line. The threshold voltage distribution of each memory unit is divided into N states, where N is a positive integer and N is less than 2 to the power of 2, and the effective bit number stored by each memory unit is less than 2.

Abstract: An antenna structure capable of transmitting a WiGig band for a head-mounted wireless transmission display device including a display screen and an overhead device is disclosed. The antenna structure includes at least two body portions, each of the body portions having at least a signal transceiving end, the body portions are respectively arranged at left and right sides of the display screen, and signal transceiving ends of the body portions are extended outward from the left and right sides of the display screen respectively.

Abstract: In some embodiments, an image sensor is provided. The image sensor includes a photodetector disposed in a semiconductor substrate. A wave guide filter having a substantially planar upper surface is disposed over the photodetector. The wave guide filter includes a light filter disposed in a light filter grid structure. The light filter includes a first material that is translucent and has a first refractive index. The light filter grid structure includes a second material that is translucent and has a second refractive index less than the first refractive index.

Abstract: A battery pack for an information handling system includes a battery cell configured to provide current to the information handling system, and a battery management unit including an output to the information handling system. The output provides a maximum continuous current (MCC) indication and a peak power (PP) indication. The battery management unit determines an amount of current that the battery cell provides to the information handling system and determines an optimum MCC value that the battery cell can provide to the information handling system. The battery management unit further provides a first value on the PP indication, the first value being greater than the optimum MCC value, sums the amount of current provided to the information handling system that is in excess of the optimum MCC value, determines that the sum is greater than a threshold, and provides a second value on the PP indication, the second value being less than the optimum MCC value.

Abstract: Pharmaceutical compositions comprising a CpG oligonucleotide, a buffer agent, and one or more salts having a total salt concentration of about 80-130 mM. A majority population of the CpG oligonucleotides in the composition is in dimeric form. Also provided herein are uses of the pharmaceutical compositions for modulating immune responses in subjects in need of the treatment, for example, cancer patient.
