A sound source device and a signal receiver are disposed at first and second ports of a target object, respectively. A sound of a specific frequency of the sound source device is introduced into the target object to generate a resonant sound wave. A computer simulates a signal generated when the resonant sound wave is received by the signal receiver and regarding the signal as reference information. The reference information comprises first data having characteristics of the resonant sound wave, and data having features of an imaginary defect formed on the target object. The features of the imaginary defect correspond to the characteristics of the resonant sound wave. When the target object has a real defect, the sound of the specific frequency of the sound source device is introduced into the target object. Features of the real defect are derived by comparing the first data with the second data.

A transfer method for expanding pitches of devices includes: providing a first substrate with micro devices having the pitches being a predetermined value in a first direction and a second direction; transferring the micro devices to a first roller by contacting it with the micro devices, wherein a pitch of contact line portions on the first roller is N times of the predetermined value; transferring the micro devices on the first roller to a second substrate; rotating the second substrate by 90 degrees; transferring the micro devices to a second roller by rolling the second roller to contact the micro devices; and then transferring the micro devices to a third substrate to expand the pitch of the micro devices in both the first and the second directions. The portions in contact with the micro devices all have adhesive layers with different adhesion operation windows.

A reaction device for chemical vapor deposition is disclosed. The reaction device includes a chamber, a susceptor, an inlet pipe unit and an outlet pipe. The susceptor is disposed within the chamber. The inlet pipe unit includes a plurality of feeding openings horizontally facing the peripheral area of the susceptor to input at least one reaction gas into the chamber. The at least one reaction gas is guided to move from the peripheral area of the susceptor and along a surface of the susceptor to reach the center of the susceptor. The outlet pipe includes a discharge opening whose position is corresponding to the center of the susceptor so as to discharge the reaction gas flowing to the center of the susceptor out of the chamber.
