摘要:
A semiconductor device includes: a substrate, a semiconductor layer including an oxide semiconductor disposed on the substrate, a barrier layer disposed on the semiconductor layer and an insulating layer disposed on the barrier layer. The semiconductor layer includes an oxide semiconductor, and the barrier layer includes a material having a lower standard electrode potential than a semiconductor material of the oxide semiconductor, a lower electron affinity than the semiconductor material of the oxide semiconductor, or a larger band gap than the semiconductor material of the oxide semiconductor. The insulating layer includes at least one of a silicon-based oxide or a silicon-based nitride, and the insulating layer includes a portion which contacts with an upper surface of the barrier layer.
摘要:
An oxide semiconductor includes a first material including at least one selected from the group consisting of zinc (Zn) and tin (Sn), and a second material, where a value acquired by subtracting an electronegativity difference value between the second material and oxygen (O) from the electronegativity difference value between the first material and oxygen (O) is less than about 1.3.

Disclosed is a method and an apparatus for optimally processing N sort queries in a multi-range scan, including: allocating a buffer based on a first number of extracted records included in the queries; extracting first data related to first attributes in a first list included in the queries and storing the extracted first data in the buffer; extracting second data related to the first attributes that are not extracted in the first list included in the queries; and updating the buffer so as to satisfy the queries by comparing the data stored in the buffer with the second data, wherein the queries are N sort queries in a multi-range scan for at least one record sorted based on the first attributes and second attributes.
摘要:
A method of detecting weight of laundry contained in a washing machine. A calibration mode is provided that is performed separately from a washing mode such that a detection error of the weight of laundry, which occurs due to external environment factors, is calibrated when the weight of laundry is detected using a motor. The calibration mode is provided to find the weight detection offset data of the washing machine based on external environment factors, and to store the weight detection offset data found. When the weight of laundry is detected in a next washing mode, the weight of laundry is calibrated by use of the weight detection offset data of the washing machine, so that the weight of laundry accommodated in the washing machine is precisely detected.
