Abstract:
PURPOSE: A semiconductor inspection device is provided to improve inspection speed by transmitting data of an algorithm pattern generator to a signal generator at high speed. CONSTITUTION: A semiconductor inspection device(100) comprises an algorithm pattern generator(120), an accelerator(130), a signal generator(140), and pin electronics(150). The algorithm pattern generator generates pattern data at first clock speed. The accelerator outputs the pattern data generated in the semiconductor inspection device at second clock speed quicker than the first clock speed. The signal generator adds timing information to the pattern data and outputs it. The pin electronics changes a signal outputted from the signal generator into a signal which is applied to a under test semiconductor device and outputs it.

PURPOSE: An RF performance inspection apparatus and an inspection method thereof are provided to shorten the RF performance inspection time. CONSTITUTION: An RF signal generator(20) generates the RF signal. An RF signal analyzer(30) analyzes the RF signal. A controller(10) sets the inspection pattern for the RF performance inspection on an object to be inspected. A plurality of monitoring signals is generated in batch based on the set inspection pattern.
Abstract:
A method and a system of multiple degree-of-freedom dynamic approximation are provided to reduce an error rate due to a noise by using an integration equation. A system of multiple degree-of-freedom dynamic approximation includes a fdriving controller(210), a detector(220), and an estimator(230). When a driving command for an object to be controlled is inputted, the driving controller provides a driving force to the object. The detector detects a driving position of the object due to the driving force from the driving controller, and a driving speed corresponding to the driving position. The estimator estimates properties of the object by using the driving force from the driving controller, and the driving position and the driving speed, which are detected from the detector.
