摘要： The present disclosure relates to a power transmitter, a resonance-type contactless power supply and a control method. The inverter circuit is controlled to provide a high-frequency AC current with a voltage strength parameter so that a current strength parameter (e.g. a peak value or an effective value of the current) of the AC current flowing through a transmitting coil and that through a receiving coil have a predetermined relationship. Thus, an equivalent load impedance is adjusted so that the system efficiency is optimized.

摘要： The present disclosure relates to a method for manufacturing a CM OS structure. Shallow trench isolation is formed in a semiconductor substrate. A first region is defined for a first MOSFET and a second MOSFET of a first type and a second region is defined for a third MOSFET and a fourth MOSFET of a second type, by shallow trench isolation. First to fourth Gates sacks are formed on the semiconductor substrate, each of which includes a gate conductor and a gate dielectric and the gate dielectric is disposed between the gate conductor and the semiconductor substrate. The first and second gate stacks are formed in the first region, and the third and fourth gate stacks are formed in the second region. The gate dielectrics of the first and third gate stacks have a first thickness, and the gate dielectrics of the second and fourth gate stacks have a second thickness larger than the first thickness. Some masks are commonly used in various steps in this process so that the number of the masks is reduced.
