摘要:
A sample with improved effect of backside positioning, fabrication method and analysis method thereof are disclosed in the present invention. The present invention has formed the arc-shaped convex structure with a certain arc at the back surface of the substrate, so that the value of the numerical aperture of the conventional lens in the positioning analysis is increased. That is that using a conventional lens of the EMMI may also obtain a better positioning analysis result of the back side of the chip. In addition, depending on the different thicknesses of the substrate, convex structures with different arcs are formed. Therefore, only one lens is used to perform a positioning analysis for different samples, so as to greatly reduce the cost of analysis.

The present invention discloses a preparation method of plan-view TEM sample used in an integrated circuit analysis. The method comprises the steps of: providing a carrying slice, and fixing a chip containing a targeted structure sample and the carrying slice on a sample holder in a horizontal direction, and putting them in a process chamber of a FIB apparatus; cutting off a piece of chip structure containing a target structure sample by adopting a FIB; and welding the piece of chip structure on the flat and clean side of the carrying slice by using a nano-manipulator; after being taken out from the process chamber of the FIB apparatus, the carrying slice welded with the chip structure is adjusted to vertical direction, and is put in the process chamber of the FIB apparatus again; transferring and welding the chip structure on the TEM copper grid by using the nano-manipulator; and removing one layer or multiple layers above the preset target layer from the surface layer of the chip by using the FIB to obtain the desired plan-view TEM sample.

An electronic device includes a housing. A motherboard is arranged in a first end of the housing. A hard disk drive area is arranged at a second end of the housing. A cooling module is arranged at the housing between the motherboard and the hard disk drive area. The cooling module includes a chassis and a semiconductor chilling plate received in the chassis. An outside airflow flows through the hard disk drive area, and then flows through the semiconductor chilling plate to be cooled. The cooled airflow is driven to flow through the motherboard.

Plant viral vectors have great potential in rapid production of proteins, but no simple. Here a geminivirus-based system for high-yield and rapid production of oligomeric protein complexes, including virus-like particle (VLP) vaccines and monoclonal antibodies (mAbs) is described. In particular, a single vector that contains two non-competing replicons for transient expression in Nicotiana benthamiana leaves is described. The correct assembly of these subunit proteins into functional oligomeric structures (VLPs or full-size mAb) is also described. This system advances plant transient expression technology by eliminating the need for non-competing viruses, and thus, enhances the realistic commercial application of this technology for producing multiple-subunit protein complexes.

A Direct Current/Direct Current (DC/DC) converter for acquiring stabilized low voltage and a telephone power supply circuit based on the DC/DC converter are provided by the present invention. The DC/DC converter includes a power level circuit (1), which receives a dynamic voltage input from an outside circuit; a tank circuit (2), which uses energy-storage elements to store the electric energy outputted from the power level circuit and outputs the electric energy to a load; and a feedback control circuit (3), which receives the voltage from the output and feeds it back to the input of the tank circuit so as to control the connection and disconnection of the input of the tank circuit and further to control output voltage of the tank circuit. By the technical solution of the present invention, which uses the energy-storage inductance to store energy, limits the output, and acquires a stabilized low voltage from a wider range output voltage by using a feedback circuit, the power consumption is reduced, and the impact on the telephone is reduced at the time of picking up and/or hanging up the telephone.
