    • Embodiments of the present disclosure provide an air duct assembly for a rotor of an electric machine and associated rotor and electric machine. The air duct assembly comprises a base plate arranged between core laminations of the rotor and comprising ventilation holes axially aligned with inlet channels of the rotor respectively; and a plurality of airflow guides axially protruding from a radial outer portion of an end surface of the base plate relative to the ventilation hole, the plurality of airflow guides comprising a plurality of first guiding members extending radially; and a plurality of second guiding members arranged between the first guiding member and the ventilation holes and radially spaced apart from the first guiding member by a predetermined distance. With the gap between the first guiding members and the second guiding members, the airflow guided by the air duct assembly is significantly improved so that heat can be taken away more effectively, and thus the cooling effect is improved. Furthermore, by replacing a whole stripe as used in conventional solutions with a two-member design according to embodiments of the present disclosure, the material for making the airflow guides, such as copper, can be significantly reduced, so that an improved cooling effect can be obtained at low cost.

    • Phase change memory (PCM) device structures are described, in which the phase change material is seamless, thereby obviating void issues that are associated with decreased device performance. Such PCM device structures can be readily formed by a trench technique in which phase change material is conformally deposited on trench side wall and bottom surfaces, followed by removal of the phase change material from the bottom surface, deposition of a dielectric passivation layer and thereafter oxide and/or nitride material, followed by CMP to remove dielectric and oxide/nitride material, and expose top surfaces of the phase change material. A top electrode then is formed in contact with the exposed top surfaces of the phase change material to provide a top electrode/PCM device structure including the seamless PCM material.
    • 描述了相变存储器(PCM)器件结构,其中相变材料是无缝的,从而消除与降低的器件性能相关联的空隙问题。 这样的PCM器件结构可以通过沟槽技术容易地形成,其中相变材料共形沉积在沟槽侧壁和底表面上,随后从底表面去除相变材料,然后沉积介电钝化层,然后氧化物 和/或氮化物材料,随后用CMP去除电介质和氧化物/氮化物材料,并暴露相变材料的顶表面。 然后,顶部电极形成为与相变材料的暴露的顶表面接触,以提供包括无缝PCM材料的顶部电极/ PCM装置结构。
