A thermosetting oligomer or thermosetting polymer is provided. The thermosetting oligomer or thermosetting polymer contains repeating units, each of which has at least one thermosetting functional group in the side chain and is represented by Formula 1: where repeating units include X1, A1, and Y1 subunits, sidechain units include linking unit L and thermosetting functional group Z, and n is an integer from 1 to 4. The thermosetting oligomer or thermosetting polymer has a low coefficient of thermal expansion and high or no glass transition temperature, stiffness, processability, heat resistance and mechanical properties. The thermosetting oligomer or thermosetting polymer is highly soluble, wettable and dimensionally stable and is suitable for use in films, prepregs and printed circuit boards. Further provided are a thermosetting resin composition including the thermosetting oligomer or thermosetting polymer and a printed circuit board using the composition.

Provided is a signal generation device used for an information input method using an ultrasonic signal. Contact electrodes which are formed in a flexible printed circuit board to be in contact with an ultrasonic wave generation unit and reference signal generation units are disposed in a row, so that a length of the flexible printed circuit board can be reduced. Accordingly, in comparison with a signal generation module in the related art, a length of the signal generation module can be reduced, so that the signal generation device can be miniaturized. In addition, in order to maintain the contact between contact electrodes of the flexible printed circuit board and the ultrasonic wave generation unit, the contact electrodes which are in contact with the ultrasonic wave generation unit and the flexible printed circuit board are surrounded by a contact maintaining member which is constructed with a cylindrical elastic member.

A novel multi-functional linear siloxane compound, a siloxane polymer prepared from the siloxane compound, and a process for forming a dielectric film by using the siloxane polymer. The linear siloxane polymer has enhanced mechanical properties (e.g., modulus), superior thermal stability, a low carbon content and a low hygroscopicity and is prepared by the homopolymerization of the linear siloxane compound or the copolymerization of the linear siloxane compound with another monomer. A dielectric film can be produced by heat-curing a coating solution containing the siloxane polymer which is highly reactive. The siloxane polymer prepared from the siloxane compound not only has satisfactory mechanical properties, thermal stability and crack resistance, but also exhibits a low hygroscopicity and excellent compatibility with pore-forming materials, which leads to a low dielectric constant. Furthermore, the siloxane polymer retains a relatively low carbon content but a high SiO2 content, resulting in its improved applicability to semiconductor devices. Therefore, the siloxane polymer is advantageously used as a material for dielectric films of semiconductor devices.

The present invention includes a class-E power amplifier, comprising a driver stage (DS) including a first power amplifier with transistors, to which an input signal is inputted; a main stage (MS), including a second power amplifier with transistors, whose input is connected to the output of the DS; and a first LC resonator whose one end is connected to the output of the DS and the other end to the ground as an AC equivalent circuit and a second LC resonator whose one end is connected to the input of the MS and the other end to the ground as an AC equivalent circuit. In accordance with the present invention, as the voltage stress is reduced on the CMOS class-E power amplifier, the application of the high power supply voltage may be allowed and therefore the load impedance may be high while the same efficiency is maintained.
