  • Patent number: 9910091
    Abstract: A method for auto-calibrating a semiconductor component tester is provided. The semiconductor component tester includes a wafer tester or a package IC tester. Firstly, an initial tester setting value and an initial board setting value are acquired through a calibration board. Then, the test record of the semiconductor component corresponding to each test time and the tester parameter and the board parameter for testing the semiconductor component are recoded. If the semiconductor component fails the test, the semiconductor component is tested again according to the previously-passed tester parameter and the previously-passed board parameter, or the semiconductor component is tested again after the tester parameter and the board parameter are adjusted. The method is capable of correcting the improper test result from the improper tester parameter.

  • Patent number: 5984784
    Abstract: A game apparatus with fast-access keys that can help the player to gain instant access to selected games is provided. The provision of the fast-access keys allows more friendliness and popularity to the game apparatus. The game apparatus includes a storage unit containing a plurality of game programs; a triggering device associated with a number of fast-access keys; and a control device coupled between the triggering device and the storage unit. Each key and key combination of the fast-access keys on the triggering device corresponds to a certain one of the game programs stored in the storage unit. The pressing of each key and key combination can cause the generation of a corresponding trigger signal which is transferred to the control device. In response to the trigger signal, the control device generates and transfers a start signal to the storage unit so as to retrieve a corresponding game program from the storage unit.
