Abstract: A method is provided for forming a metal gate using a gate last process. A trench is formed on a substrate. The profile of the trench is modified to provide a first width at the aperture of the trench and a second width at the bottom of the trench. The profile may be formed by including tapered sidewalls. A metal gate may be formed in the trench having a modified profile. Also provided is a semiconductor device including a gate structure having a larger width at the top of the gate than the bottom of the gate.

Abstract: A method of forming a semiconductor device includes providing a semiconductor substrate; forming a gate stack on the semiconductor substrate; forming a gate spacer adjacent to a sidewall of the gate stack; thinning the gate spacer; and forming a secondary gate spacer on a sidewall of the gate spacer after the step of thinning the gate spacer.

Abstract: A radioactive material for inhibiting cancer and a preparation method thereof are disclosed. The radioactive material for inhibiting cancer is M-SOCTA-Z and M is a radioactive nuclide such as 188Re or 99mT while Z is protein or peptides having amino acid with NH or NH2 group. The preparation method of the radioactive material for inhibiting cancer includes steps of: reacting SOCTA with protein or peptide. Ester (—COOR) in SOCTA reacts with amines (—NH, —NH2) in protein or peptide to form peptide bond. Thus SOCTA-protein or SOCTA-peptide complex is produced. Then these SOCTA-protein complex reacts with radioactive nuclide M so as to generate M-SOCTA-protein or M-SOCTA-peptide. In an embodiment of the present invention, monoclonal antibody Herceptin is applied to bind with SOCTA and in combination with radiation-based therapy, effects of cancer treatment (such as breast cancer) are enhanced.

Abstract: A method of forming an integrated circuit structure includes providing a semiconductor substrate; forming patterned features over the semiconductor substrate, wherein gaps are formed between the patterned features; filling the gaps with a first filling material, wherein the first filling material has a first top surface higher than top surfaces of the patterned features; and performing a first planarization to lower the top surface of the first filling material, until the top surfaces of the patterned features are exposed. The method further includes depositing a second filling material, wherein the second filling material has a second top surface higher than the top surfaces of the patterned features; and performing a second planarization to lower the top surface of the second filling material, until the top surfaces of the patterned features are exposed.

Abstract: The present invention is to invent a novel method for testing the radiochemical purity of Tc-99m-TRODAT-1 through a high performance liquid chromatography on a widely available C-18 column.

Abstract: A caster structure including a seat body, a linking member, a caster seat and a lower bearing cover. The linking member is integrally formed with an upper bearing cover. The seat body is formed with a differential fixing hole and the top of the linking member is formed with a fixing section. The shape of the cross-section of the fixing section is an internal tangential circle of the differential fixing hole. When the fixing section is passed through the fixing hole and compressed and fixedly riveted, the fixing section will form a differential section complementary to the fixing hole. Accordingly, the linking member is firmly connected with the seat body without rotation.

Abstract: The controller is a logical network which, when interfaced with a mechanical system or an electromechanical system, will cause the output variable of the system to closely follow any command signal received. It comprises shift registers, memory banks, accumulators, arithmetic units and preferably no software. Universal Controller keeps the error between the output of the model and the output of the control system small, regardless of the transfer function of the controlled system by adjusting a number of gains in its internal feedback loop in accordance with that error. It therefore can be applied to an arbitrary electromechanical system without prior knowledge of its transfer function.

Abstract: The Controller is a logical network which, when interfaced with a mechanical system or an electromechanical system, will cause the output variable of the system to closely follow any command signal received. It comprises shift registers, memory banks, accumulators, arithmetic units and preferably no software. The device works in two stages. In the first stage it identifies the unit-impulse response of the system piece-by-piece while using the accumulated information to control the system at the same time. In the second stage it continually readjusts the stored information at each clock pulse by comparing the observed output signal and the command signal, while generating the required control variable based on the updated information. Its operation incorporates a learning process which emulates a simple form of human intelligence.
