Abstract: In an embodiment, a package includes an integrated circuit device attached to a substrate; an encapsulant disposed over the substrate and laterally around the integrated circuit device, wherein a top surface of the encapsulant is coplanar with the top surface of the integrated circuit device; and a heat dissipation structure disposed over the integrated circuit device and the encapsulant, wherein the heat dissipation structure includes a spreading layer disposed over the encapsulant and the integrated circuit device, wherein the spreading layer includes a plurality of islands, wherein at least a portion of the islands are arranged as lines extending in a first direction in a plan view; a plurality of pillars disposed over the islands of the spreading layer; and nanostructures disposed over the pillars.

Abstract: A fluid compressing system includes: a rotary compressor including a housing defining an oil chamber and an oil-releasing port in fluid communication with the oil chamber; a discharging pipeline connected to the housing for passage of a high pressurized fluid therethrough; an oil-adjusting tank connected to the discharging pipeline and the oil-releasing port for receiving lubricant oil from the oil chamber so as to alleviate oil swirling in the oil chamber; an oil filter connected to the discharging pipeline for separating the lubricant oil from the high pressurized fluid; and a first capillary connected to the oil filter and the housing for recycling filtered lubricant oil from the oil filter into the oil chamber.
