Description

[0001] The present invention relates to the field of semiconductor testing technologies, and in particular, to a method, system, device, equipment and medium for testing a single bare die of Mono flash. Background Art

[0002] Single-board flash memory (Mono flash) is a high-density flash memory architecture that integrates multiple independent dies. It achieves large-capacity storage by stacking or arranging multiple bare dies on a single packaging substrate. In the semiconductor manufacturing process, a bare die refers to an independent chip unit that has been cut from a silicon wafer (wafer) and is not yet packaged. The testing and failure analysis (FA) of bare dies are important links to ensure the reliability of chips: on the one hand, electrical testing needs to be performed on the original bare dies after wafer cutting to screen qualified units; on the other hand, for the failed packaged chips, de-encapsulation treatment is required to expose the bare die and locate the failed die and the failure type of the failed die.

[0003] However, the current industry's testing solutions for single bare dies have significant limitations: firstly, traditional test circuit boards usually only support a limited type of test items (such as basic function verification), and it is difficult to cover test requirements with high signal quality requirements and measurement accuracy requirements (such as ICC power consumption test, Erase test, Program test, etc.); secondly, the test hardware (such as probe cards, fixtures) is bound to specific models or generations of Nand Flash chips, resulting in poor compatibility and inability to adapt to diverse chip designs; thirdly, the test process relies on manual replacement of hardware and reconfiguration of parameters, with low efficiency and prone to introducing operation errors. These problems seriously restrict the flexibility and generality of the testing link in the Mono flash manufacturing process. Summary of the Invention

The Mono flash single bare die test system includes an ATE computer 10, an ATE test head 20, a test fixture 30, a connection line 40, a loading platform 50, and a probe card 60.

[0036] The ATE computer 10 is connected to the ATE test head 20, and the test fixture 30 is loaded on the ATE test head 20; both ends of the connection line 40 are respectively connected to the test fixture 30 and the probe card 60.

The Mono flash single bare die test system is used to execute the Mono flash single bare die test method provided by the embodiment of the present invention.

[0037] Specifically, referring to Figure 1 , an embodiment of the present invention provides a Mono flash single bare die test method. As Figure 1 shown, the method includes the following steps:

[0038] S1, determine the test program corresponding to the die to be tested, and load the test program into the ATE computer.

[0039] In specific implementation, the embodiment of the present invention can implement various types of tests on the die to be tested, and can implement Open short test, Leakage test, Reset test, ReadTemp test, ReadFlash ID test, Read UID test, ScanFBB test, Erase test, Program test, ICC current test, etc.

[0040] A corresponding test program is pre-written for each test. Each die to be tested corresponds to a test program based on its test items. The test program can be one or more, and the present invention does not specifically limit this.

[0041] In the present invention, the test program required for the die to be tested is loaded into the ATE computer.

[0042] In some embodiments, the above step "determine the test program corresponding to the die to be tested" specifically includes: obtaining the type of the die to be tested; based on the type of the die to be tested, determining the test program corresponding to the die to be tested.

[0043] In specific implementation, a corresponding relationship between the type of the chip and the test program is established in advance. After that, after determining the type of the chip, the test program corresponding to the die to be tested is determined based on the type of the chip and the corresponding relationship.

[0044] Understandably, the type of the chip can be determined by user input or based on the identification information of the chip. The present invention does not specifically limit this.

[0045] S2. Determine the needle card corresponding to the die to be tested, place the die to be tested on the loading platform, and connect the die to be tested with the needle card.

In the embodiments of the present invention, determine the needle card corresponding to the die to be tested, place the die to be tested on the loading platform, and connect the die to be tested with the needle card.

[0047] Connect the die to be tested with the needle card. The specific implementation method is as follows: Align the pins of the needle card with the PADs of the die to be tested; adjust the distance between the pins of the needle card and the die to be tested so that the pins of the needle card tightly contact the PADs of the die to be tested.

[0048] Specifically, the needle card is placed on a liftable lifting device, and by adjusting the height of the lifting device, the pins of the needle card tightly contact the PADs of the die to be tested.

[0049] In some embodiments, the above step of "determine the needle card corresponding to the die to be tested" specifically includes: obtaining the type of the die to be tested; based on the type of the die to be tested, determine the needle card corresponding to the die to be tested.

[0050] In specific implementation, a corresponding relationship between the type of the chip and the needle card is established in advance. After that, after determining the type of the chip, based on the type of the chip and the corresponding relationship, determine the needle card corresponding to the die to be tested.

[0051] Understandably, the type of the chip can be determined by user input or based on the identification information of the chip. The present invention does not specifically limit this.

[0052] S3. Install a test fixture on the ATE test head and connect the needle card with the test fixture.

[0053] In specific implementation, load the test fixture onto the ATE test head so that the test fixture is electrically connected to the ATE test head.

[0057] When replacing and testing different types of dies under test, load the corresponding test program in the ATE computer and replace the corresponding needle card for testing. It can be seen that the embodiments of the present invention are universal, capable of performing various different types of tests on different types of dies under test, with high efficiency and wide applicability.

[0058] It should be noted that the replacement of the needle card can be carried out manually or automatically. The present invention does not limit this.

The ATE test fixture realizes the connection between the test machine resources and the bare die through the connecting wires and the probe card. According to the chip characteristics, the corresponding ATE test program is written on the ATE computer. The test program controls the input and output of the ATE test machine resources, and the ATE test machine resources are connected to the bare die, so as to realize the control of the driving and comparison of the bare die signals and achieve the purpose of testing.
