Abstract: A two-phase immersion-type heat dissipation structure having skived fin with high porosity is provided. The two-phase immersion-type heat dissipation structure having skived fin with high porosity includes a porous heat dissipation structure having a total porosity that is equal to or greater than 5%. The porous heat dissipation structure includes a porous substrate and a plurality of porous and skived fins. The porous substrate has a first surface and a second surface that face away from each other. The second surface of the porous substrate is configured to be in contact with a heating element that is immersed in a two-phase coolant. The plurality of porous and skived fins are integrally formed on the first surface of the porous substrate by skiving. A first porosity of the plurality of porous and skived fins is greater than a second porosity of the porous substrate.

Abstract: In a method of manufacturing a semiconductor device, a fin structure is formed by patterning a semiconductor layer, and an annealing operation is performed on the fin structure. In the patterning of the semiconductor layer, a damaged area is formed on a sidewall of the fin structure, and the annealing operation eliminates the damaged area.

Abstract: The application relates to a method for developing the agitation system of a scale-up polymerization vessel. A simulated prediction model is obtained by use of a small polymerization vessel and by integrating Taguchi experimental design method with artificial intelligence (AI) neural network. Accordingly, vessel parameters for the agitation system of a scale-up polymerization vessel can be rapidly and accurately predicted based on simulation qualities thereof, further facilitating a construction of the agitation system of a scale-up polymerization vessel.

Abstract: An adjustable structure for the footrest ring of a chair includes a footrest ring, a sleeve, a nut, an adjusting rod and two retaining rings. The sleeve is received in a through hole of a fixed base of the footrest ring, having a wall cut with an oblique groove. The nut is secured in an insert hole of the fixed base of the footrest ring. The adjusting rod has one end screwed in the nut and another end extending out of the fixed base. The two retaining rings are respectively engaged in the engage groove at an upper and a lower outer wall of the sleeve. Thus, the footrest ring can conveniently be adjusted in height and stably positioned on the support tube of a chair.

Abstract: A semiconductor structure fabricating method includes the following steps. Firstly, a silicon substrate is provided. The silicon substrate has a first surface and a second surface. In addition, a first semiconductor structure is formed on the first surface of the silicon substrate. Then, the second surface of the silicon substrate is textured as a rough surface. Then, a first electrode layer is formed on the rough surface.

Abstract: A transmission mechanism for a scanner includes a frame having a plurality of holes with different sizes and a series of gears mated with each other through different numbers of teeth. Due to different locations of where the transmission mechanism are mounted, the frame is able to be adapted to different type of motors.
