摘要:
A touch operation method applied to an electronic device having a curved screen, where the curved screen includes a side edge of the electronic device. After detecting that the side edge is touched, the electronic device determines a target region, where the target region is a contact region of a user on the side edge in a holding mode. The electronic device prompts a location of the target region. After detecting a touch operation performed by the user on the target region, the electronic device performs a corresponding response operation for the touch operation.

A SiGe HBT has an inverted heterojunction structure, where the emitter layer is formed prior to the base layer and the collector layer. The frequency performance of the SiGe HBT is significantly improved through a better thermal process budget for the base profile, essential for higher cut-off frequency (fT) and a minimal collector-base area for a reduced parasitic capacitance, essential for higher maximum oscillation frequency (fmax). This inverted heterojunction structure can be fabricated by using ALE processes to form an emitter on a preformed epitaxial silicide, a base over the emitter and a collector over the base.

A metal silicide thin film and ultra-shallow junctions and methods of making are disclosed. In the present disclosure, by using a metal and semiconductor dopant mixture as a target, a mixture film is formed on a semiconductor substrate using a physical vapor deposition (PVD) process. The mixture film is removed afterwards by wet etching, which is followed by annealing to form metal silicide thin film and ultra-shallow junctions. Because the metal and semiconductor dopant mixture is used as a target to deposit the mixture film, and the mixture film is removed by wet etching before annealing, self-limiting, ultra-thin, and uniform metal silicide film and ultra-shallow junctions are formed concurrently in semiconductor field-effect transistor fabrication processes, which are suitable for field-effect transistors at the 14 nm, 11 nm, or even further technology node.

The present disclosure is related to semiconductor technologies and discloses a semiconductor device and its method of making. In the present disclosure, a transistor's source and drain are led out by concurrently formed metal-semiconductor compound contact regions at the source and drain and metal-semiconductor compounds in vias formed at positions corresponding to the source and drain. Because the metal-semiconductor compound has relatively low resistivity, the resistance of the metal-semiconductor compounds in the vias can be minimized. Also, because the material used to fill the vias and the material forming the source/drain contact regions are both metal-semiconductor compound, contact resistance between the material filling the vias and the metal-semiconductor compound source/drain contact regions can be minimized. Furthermore, because the material filling the vias is metal-semiconductor compound, the conducting material in the vias and dielectric material in the insulator layer can form good interface and have good adhesion properties, and the conducting material would not cause structural damage in the dielectric material. Thus, there is no need to form a barrier layer between the insulator layer and the material filling the vias.
