Abstract: An interactive system with movement sensing capability, comprising: an inertial sensing unit disposed on a movable object so as to sense a movement of the movable object and generate a corresponding signal; a control unit connected to the inertial sensing unit so as to transmit the signal; and a multi-media unit receiving the signal so as to display a corresponding first image and a second image interacted with the first image.

Abstract: A method for determining properties or a thin film includes the steps of: providing a piezoelectric substrate; providing a slanted finger interdigital transducer unit that includes a transmitter port and a receiver port on the piezoelectric substrate; forming the thin film on the piezoelectric substrate between the transmitter port and the receiver port; applying an input signal to the transmitter port; and measuring a phase difference, which corresponds to the input signal, from the receiver port. Accordingly, properties of the thin film are determined based on the measured phase difference. An apparatus for realizing the method is also disclosed.

Abstract: The present invention relates to a method for forming an ultra thin oxide layer by using an ozonated water, which comprises the steps of dissolving an ozone-containing gas in deionized water to form an ozonated water, and immersing a silicon wafer in the ozonated water to from an ultra thin oxide layer on the wafer. The method according to the present invention can substitute for the conventional high temperature process for growing an ultra thin oxide layer and form an ultra thin oxide layer in high density and high uniformity by taking the advantages of time-saving, energy-saving but without conducting at an elevated temperature.
