A heat dissipating device includes a chamber body, a heat sink, a pipe, a first capillary structure and N vapor channels. The chamber body has an evaporation chamber and a compensation chamber, wherein the evaporation chamber has a vapor outlet and the compensation chamber has a liquid inlet. The heat sink is disposed on an outer wall of a first side of the chamber body and at least covers the compensation chamber. The pipe is installed within the heat sink, wherein a first end of the pipe is connected to the vapor outlet and a second end of the pipe is connected to the liquid inlet. The first capillary structure is formed in the evaporation chamber. The N vapor channels are formed in the first capillary structure. The N vapor channels and the compensation chamber are isolated by the first capillary structure.

A stress compensation for use in packaging, and a method of forming, is provided. The stress compensation layer is placed on an opposing side of a substrate from an integrated circuit die. The stress compensation layer is designed to counteract at least some of the stress exerted structures on the die side of the substrate, such as stresses exerted by a molding compound that at least partially encapsulates the first integrated circuit die. A package may also be electrically coupled to the substrate.

A film coating system for coating an object includes a working station and an isolating device. The object is disposed on the working station, and the isolating device is utilized to isolate the object. The isolating device includes a body generating a first power, a first working fluid, a second working fluid, a first guiding portion and a second guiding portion. The first guiding portion guides the first working fluid to pass through the body, thereby forming a first working region to coat the object thereon. The second guiding portion guides the second working fluid excited by the first power of the body to pass through the body, thereby forming a second working region to separate the first working region from the object.

A plasma deposition apparatus is provided. The plasma deposition apparatus comprises a chamber. A pedestal is placed in the chamber. A plasma generator is placed in the chamber and over the pedestal. The plasma generator comprises a plasma jet for plasma thin film deposition having a discharge direction angle θ1 larger than 0° and less than 90° between a normal direction of the pedestal and the discharge direction of the plasma jet. A gas-extracting pipe extends into the chamber and over the pedestal. The gas-extracting pipe provides a pumping path for particles and side-products having a pumping direction angle θ2 larger than 0° and less than 90° between the normal direction of the pedestal and the pumping direction of the gas-extracting pipe. The chamber is kept at an ambient atmospheric pressure.
