Abstract: An integrated circuit device includes a gate stack disposed over a substrate. A first L-shaped spacer is disposed along a first sidewall of the gate stack and a second L-shaped spacer is disposed along a second sidewall of the gate stack. The first L-shaped spacer and the second L-shaped spacer include silicon and carbon. A first source/drain epitaxy region and a second source/drain epitaxy region are disposed over the substrate. The gate stack is disposed between the first source/drain epitaxy region and the second source/drain epitaxy region. An interlevel dielectric (ILD) layer disposed over the substrate. The ILD layer is disposed between the first source/drain epitaxy region and a portion of the first L-shaped spacer disposed along the first sidewall of the gate stack and between the second source/drain epitaxy region and a portion of the second L-shaped spacer disposed along the second sidewall of the gate stack.

Abstract: A method for preparing a bifunctional film, including: (a) drying a first polymer solution to form a film to form an anti-adhesion layer, and (b) drying a second polymer solution over the anti-adhesion layer to form a film to form an attachment layer. The first polymer solution includes a first hydrophobic solution and a first hydrophilic solution, and in the first polymer solution, the weight ratio of the solute of the first hydrophobic solution to the solute of the first hydrophilic solution is 1:0.01-1. Moreover, the second polymer solution is composed of a second hydrophilic solution.

Abstract: A minimally invasive surgical device includes a main body, a buffer assembly and a cutter bit. The main body includes an inner tube and an outer tube, wherein the inner tube is disposed in the outer tube. An end of the buffer assembly is connected to the inner tube. The cutter bit is connected to another end of the buffer assembly, wherein the cutter bit has a cutting portion. When the cutting portion is in contact with an object, the buffer assembly is adapted to enable the cutter bit to move relatively to the inner tube to decrease a cutting force between the cutting portion and the object, and is adapted to enable the cutting portion to be tilted with a surface of the object.

Abstract: An implanting device is used for implanting a membrane in a biological tissue. The implanting device includes a sleeve, a membrane storage element, an injection element and a bubble generating element. The membrane storage element is fixed at the sleeve. The injection element is inserted in the sleeve and the membrane storage element, and includes a capturing end and connecting end. The capturing end is for capturing the membrane and has a hole. The bubble generating element is connected to the connecting end, and is for providing a gas that is then outputted via the hole. By the rotation of the injection element, the capturing end extends straight out of the membrane storage element or retracts straight into the membrane storage element.

Abstract: A cartilage repair implant, an auxiliary surgical tool kit and a cartilage repair system are provided. The cartilage repair implant includes a body and a plurality of pins. The body is a porous structure and is configured to carry cartilage repair material. The pins are fixed to the body for being inserted into a patient's bone. The auxiliary surgical tool kit includes a positioning sleeve and a click tool. The positioning sleeve has a through passage. A first alignment structure is disposed on the sidewall of the through passage. The click tool includes an outer tube and a push rod. A second alignment structure mutually aligned with the first alignment structure is disposed on the outer wall of the outer tube. The outer tube is configured to pass through the through passage. The push rod is slidably disposed in the outer tube. One end of the outer tube has a shaping blade for slicing a to-be-implanted region on an affected area of the patient.
