Abstract: A media docking device includes an input circuit, an output circuit and a processing circuit. The input circuit is electrically connected to a media source device for receiving media data. The output circuit is electrically connected to a media play device. The processing circuit is electrically connected to the input circuit and the output circuit. The processing circuit determines if a verification procedure is passed. If the verification procedure is passed, the processing circuit transfers the media data to the media play device. If the verification procedure is not passed, the processing circuit limits a transmission of the media data, such that the media data will not be completely played by the media play device.

Abstract: A media docking device includes an input module, an output module and a processing module. The input module is electrically connected to a media source device for receiving media data. The output module is electrically connected to a media play device. The processing module determines if an instruction is received from the media source device or a remote device. If the instruction is not received, the processing module transfers the media data to the output module to transmit to the media play device. If the instruction is received, the processing module limits a transmission of the media data according to the instruction, such that the media data will not be completely played by the media play device.

Abstract: A method includes rotating a wafer, dispensing a liquid from a center of the wafer to a peripheral edge of the wafer to control a temperature of the wafer, and etching an etch layer of the wafer with an etchant during or after dispensing the liquid. The liquid is dispensed through a nozzle.

Abstract: Embodiments of the present disclosure relates to a wet bench processing including an in-situ pre-treatment prior to performing the first set of wet bench operations. The pre-treatment may include a pre-clean operation and/or a pre-heat operation. The pre-treatment may be performed in one of the existing ONB tanks without requiring adding new tanks to an existing wet bench tool. The pre-clean operation removes particles from a batch of wafers to avoid or reduce cross-contamination and defect issues, thus improving the yield rate of the wet bench process. The pre-heat operation provides better control and stabilize the temperature in the CHB tank to stabilize the process, such as to stabilize an etch rate.

Abstract: A method of forming a semiconductor device includes soaking a batch of wafers in a first cleaning liquid, replacing the first cleaning liquid with a second cleaning liquid, soaking the batch of wafers in the second cleaning liquid, and soaking the batch of wafers in an etchant. The first cleaning liquid has a first temperature. The second cleaning liquid has a second temperature. The etchant has a third temperature. The second temperature is between the first temperature and the third temperature.

Abstract: A method for etching an etch layer formed on a front side of a wafer and a wafer etching apparatus are provided. The wafer etching apparatus includes a first flow channel, a temperature-regulating module, and a second flow channel. The first flow channel is configured to carry a preheated/precooled liquid for controlling a temperature of a wafer. The temperature-regulating module is coupled to the first flow channel. The temperature-regulating module is configured to control a temperature of the liquid in the first flow channel. The second flow channel is configured to carry an etchant for etching an etch layer formed on a front side of the wafer. The method includes: controlling the temperature of the wafer by using the preheated/precooled liquid; and etching the etch layer with the etchant.

Abstract: A method of cleaning a substrate such as semiconductor substrate for IC fabrication is described that includes cleaning the semiconductor substrate with a first mixture of ozone and one of an acid and a base, followed by a second mixture of ozone and the other one of the acid and the base. The cleaning mixtures may further include de-ionized water. In an embodiment, the mixture is sprayed onto a heated substrate surface. The acid may be HF; the base may be NH4OH.
