Abstract: A semiconductor package includes a circuit substrate, a die, a frame structure, and a heat sink lid. The die is disposed on the circuit substrate and electrically connected with the circuit substrate. The die includes two first dies disposed side by side and separate from each other with a gap between two facing sidewalls of the two first dies. The frame structure is disposed on the circuit substrate and surrounding the die. The heat sink lid is disposed on the die and the frame structure. The head sink lid has a slit that penetrates through the heat sink lid in a thickness direction and exposes the gap between the two facing sidewalls of the two first dies.

Abstract: A device includes a first die, an interconnect structure, a RDL layer, a guard structure and an underfill layer. The interconnect structure is electrically connected to the first die. The RDL layer is disposed in a dielectric layer. The guard structure is disposed in the dielectric layer to define a connector region, wherein the guard structure and the interconnect structure are disposed on opposite sides of the die. The underfill layer surrounds the interconnect structure, the first die and the guard structure, wherein the underfill layer is kept outside of the connector region by the guard structure.

Abstract: A flexible clean energy power generation device with high power efficiency, which is a multi-film structure, includes an internal conductive support layer and an ion transport layer. The internal conductive support layer is formed by coating a conductive material onto a hydrophilic substrate; the ion transport layer is formed by coating a polyelectrolyte onto an outer side of the internal conductive support layer. After a solution is dropped on the device, the solution produces a capillary pressure difference by capillary action and evaporation phenomena to drive water molecules and counterions of the solution to move from a wet side to a dry side, thus producing a potential difference. Without an external pressure, the device uses a layered two-dimensional conductive material together with a polyelectrolyte, realizing a self-electrokinetic power generation with high energy output and long-life by capillary action and evaporation phenomena with using pure aqueous solution or other electrolyte solutions.

Abstract: A flexible long-lasting clean energy power generation device with spontaneous moisture absorption is a multi-layer film structure including a hydrophilic support substrate, a conductive layer and a moisture absorbent layer. The conductive layer is coated on an outer side of the hydrophilic support substrate and has a first section and a second section, and the moisture absorbent layer is coated on the first section of the conductive layer, so that the flexible long-lasting clean energy power generation device is formed into an asymmetrical structure. The moisture absorbent layer captures moisture from the ambient environmental humidity, and the moisture forms a capillary pressure difference by a capillary action and an evaporation, so that water molecules and ions move from the wet area of the moisture absorbent layer to the dry area of the second section to form an electric potential difference.

Abstract: A method for detecting the zeta potentials of nanopores and nanoparticles mainly uses an electrokinetic mechanism with a force balance exerted on particles in a nanopore and a current sensing technology to measure the zeta potential of the nanopore accurately, and then uses the measured zeta potential of the pore to further measure the zeta potential of the electrically charged nanoparticle passing through the pore. This method does not need to analyze the detailed spectrum of the current blockage signals and purchase expensive standard item particles, so that this method has high accuracy and less limitation than the conventional method and achieves the effects of simplifying the measurement process and lowering the measurement cost significantly. For soft nanoparticles, this method can sense the zeta potential of particles more accurately to improve the value of the method of this invention.
