Abstract: A method of promoting adhesion between a dielectric layer of a semiconductor device and a metal fill deposited within a trench in the dielectric layer, including performing an ion implantation process wherein an ion beam formed of an ionized dopant species is directed into the trench at an acute angle relative to a top surface of the dielectric layer to form an implantation layer in a sidewall of the trench, and depositing a metal fill in the trench atop an underlying bottom metal layer, wherein the metal fill adheres to the sidewall.

Abstract: The present invention provides a wireless communication method of an electronic device, wherein the electronic device includes a first radio and a second radio, a maximum bandwidth or a maximum. NSS supported by the first radio is different from a maximum bandwidth or a maximum NSS supported by the second radio. The wireless communication method includes the step of: using the first radio to communicate with another electronic device; determining if parameters of the electronic device satisfy a condition; and in response to the parameters of the electronic device satisfying the condition, enabling the second radio and using the second radio to communicate with the another electronic device, and disabling the first radio.

Abstract: A read/write method includes: applying a read command to a memory device, the read command pointing to address information, reading to-be-read data from a storage cell corresponding to the address information to which the read command points, and if an error occurs in the to-be-read data, storing the address information to which the read command points in a preset storage space. The read/write operation is not performed on the address information stored in the preset storage space when the user executes the read or write operation on the memory device, which avoids a data error or data loss and greatly improves the reliability and prolongs the service life of the memory device.

Abstract: The embodiments provide a method for reading and writing and a memory device. The method includes: applying a read command to the memory device, the read command pointing to address information; reading data to be read out from a memory cell corresponding to the address information pointed to by the read command; and storing the address information pointed to by the read command into a preset memory space if an error occurs in the data to be read out, and backing up the address information stored in the preset memory space into a non-volatile memory cell according to a preset rule.

Abstract: A double-talk state detection method includes: calculating an energy ratio between a first energy of an error signal in each sub-band of M sub-bands and a second energy of a filtered signal in the same sub-band as the error signal, thereby obtaining M energy ratios, where the error signal is a difference between an input signal collected by a microphone and the filtered signal, the filtered signal is a signal obtained after performing filtering process on a reference signal, and M is a positive integer; performing a first smoothing processing on the M energy ratios to obtain M first energy smoothing ratios, and performing a second smoothing processing on the M first energy smoothing ratios to obtain M second energy smoothing ratios; performing double-talk state detection based on the M first energy smoothing ratios and the M second energy smoothing ratios to determine a state of the input signal.
