The positioning element can move the light-output element in three-dimensional space or adjust an emitting angle from an axis of the light-output element. Therefore, an optical measurement and an electrical measurement can be implemented at the same time in the silicon photonic wafer test. | 2021-02-25 |
20210055341 | DEVICES AND METHODS FOR SURGE PROTECTION DEVICE MONITORING - Example devices and methods for compensating for monitoring a surge protection device are provided. In some embodiments, a device is configured to couple to a surge protection device. The device comprises a processor that is capable of sending a DC current signal. A serial data interface is electrically connected to the processor and includes at least one shift register. The device also comprises a multiplexer coupled to the serial data interface. The serial data interface is operable to direct the DC current through the multiplexer. The device also comprises an analog to digital converter (optionally embedded within the processor) that is operable to output a digital signal corresponding to a voltage induced by the DC current signal. Returned DC signals represent surge protection device's health and a multitude of other surge module information. | 2021-02-25 |
20210055342 | HEAT SPREADERS FOR USE IN SEMICONDUCTOR DEVICE TESTING, SUCH AS BURN-IN TESTING - Heat spreaders for use in semiconductor device testing, such as burn-in testing, are disclosed herein. In one embodiment, a heat spreader is configured to be coupled to a burn-in testing board including a plurality of sockets. The heat spreader includes (i) a frame having a plurality of apertures, and (ii) a plurality of heat sinks movably positioned within corresponding ones of the apertures. When the heat spreader is coupled to the burn-in testing board, the heat sinks are configured to extend into corresponding ones of the sockets to thermally contact semiconductor devices positioned within the sockets. The heat spreader can promote a uniform temperature gradient across the burn-in board during testing of the semiconductor devices. | 2021-02-25 |

20210055344 | WAFER INSPECTION METHOD AND WAFER PROBING SYSTEM - A wafer inspection method, wherein a motorized chuck stage is controlled by a control rod to be displaced between an upper position and a lower position along Z-axis direction, to change a relative position of a wafer on the motorized chuck stage relative to a probe. The control rod is movable between an upper and an lower limit positions. The wafer inspection method includes: determining a position of the control rod based on a measurement signal; determining a first moving direction and a moving distance of the control rod based on a change of the measurement signal; generating a control signal based on the moving distance of the control rod; controlling the motorized chuck stage to be displaced along a second moving direction opposite to the first moving direction; and controlling an objective lens module to keep focusing on the wafer when the motorized chuck stage is on the move. | 2021-02-25 |
