Abstract: Doping techniques for fin-like field effect transistors (FinFETs) are disclosed herein. An exemplary method includes forming a fin structure, forming a doped amorphous layer over a portion of the fin structure, and performing a knock-on implantation process to drive a dopant from the doped amorphous layer into the portion of the fin structure, thereby forming a doped feature. The doped amorphous layer includes a non-crystalline form of a material. In some implementations, the knock-on implantation process crystallizes at least a portion of the doped amorphous layer, such that the portion of the doped amorphous layer becomes a part of the fin structure. In some implementations, the doped amorphous layer includes amorphous silicon, and the knock-on implantation process crystallizes a portion of the doped amorphous silicon layer.

Abstract: A VOC removal system removes VOCs from an exhaust fluid of a semiconductor process. The VOC removal system measures current VOC removal parameters and passes them to an analysis model trained with a machine learning process. The analysis model predicts a future VOC removal efficiency based on the current VOC removal parameters. The analysis model generates adjustment parameters based on the current VOC removal parameters and the predicted future VOC removal efficiency. A control system adjusts the VOC removal system based on the adjustment parameters.

Abstract: This application discloses a slot antenna and a terminal. The slot antenna includes a ground plane, an open slot disposed on the ground plane, a slot feeder, and a resonant circuit. The resonant circuit effectively excites a current on a surface of the ground plane, so that the ground plane becomes a primary radiator, and the antenna is a secondary radiator. Therefore, a volume of the antenna can be reduced without affecting radiation efficiency of the antenna.

Abstract: In a Vehicular Ad Hoc Network (VANET) a hybrid method combines SDMA (Space Division Multiple Access) and dynamic TDMA (Time Division Multiple Access) that divides the roadway into regions (whose size is larger than the SDMA unit) where each region is allocated a pool of radio channels based on SDMA and may contain a limited number of vehicles. Vehicles within the same region compete for and access the channels using dynamic TDMA. A channel allocation scheme that maps the pool of channels to the regions such that when a vehicle acquires multiple channels (time slots) in a region, the intervals among the channels are as uniform as possible, thus minimizing the waiting time of the messages to be broadcast by the vehicle, which is critical for safety related applications. This solution is referred to as R-SDMA (Region based SDMA).
