Abstract: A machine-learning method for semiconductor process optimization may include inputting semiconductor-related parameters into each of first neural network models and outputting, based on the semiconductor-related parameters, a predicted figure of merit of a semiconductor device as a first output value from each of the first neural network models. After a semiconductor manufacturing process is performed with a semiconductor manufacturing parameter, electrical measurement parameter values may be measured using one or more measuring devices. The semiconductor-related parameters may include electrical measurement parameter values measured on one or more semiconductor devices. The method may also utilize a feedback loop between an output and an input of the first neural network models so that the electrical measurement parameter values can be updated based on an output value of the first neural network models. A second neural network model may also be used. A computing device and a system are also disclosed.

Abstract: An artificial bladder is provided, including: a main body which includes an inlet port, an outlet port, an inner wall that forms a first reservoir portion configured to store urine between the inlet port and the outlet port and that is expandable and contractible. An outer wall forms a second reservoir portion configured to surround at least a partial region of the inner wall. A sensor is attached to the inner wall, has a surface having a wrinkled structure, and is provided so that, when the volume of the first reservoir portion increases, the wrinkled structure stretches out and resistance of the sensor changes. A control unit is provided to discharge the urine in the first reservoir portion through the outlet port according to a result detected by the sensor.
