  • Publication number: 20240128216
    Abstract: A bonding structure that may be used to form 3D-IC devices is formed using first oblong bonding pads on a first substrate and second oblong bonding pads one a second substrate. The first and second oblong bonding pads are laid crosswise, and the bond is formed. Viewed in a first cross-section, the first bonding pad is wider than the second bonding pad. Viewed in a second cross-section at a right angle to the first, the second bonding pad is wider than the first bonding pad. Making the bonding pads oblong and angling them relative to one another reduces variations in bonding area due to shifts in alignment between the first substrate and the second substrate. The oblong shape in a suitable orientation may also be used to reduce capacitive coupling between one of the bonding pads and nearby wires.

  • Publication number: 20220230291
    Abstract: A method for detecting defects in products revealed by images of the products inputs images of the flaw-free products into an autoencoder for model training to obtain reconstructed images. The images are further processed to obtain target images. A group of testing errors are obtained by comparing the reconstructed images and the target images. An error threshold is selected from the group of the testing errors according to a specified rule. A to-be-analyzed image is inputted for obtaining a candidate be-analyzed reconstructed image, a candidate be-analyzed target image, and a potential be-analyzed error between the candidate be-analyzed reconstructed image and the candidate be-analyzed target image. A result of the to-be-analyzed image confirms defects existing or defects not existing according to the potential be-analyzed error and the error threshold. A defect detection apparatus, an electronic device, and a non-transitory computer-readable storage medium applying the method are also disclosed.

  • Publication number: 20220207707
    Abstract: A method for detecting defects in products from images thereof and an electronic device applying the method inputs a defect image repair data set into an autoencoder to train the autoencoder, and generates a reconstructed image, calculates a reference error value between the sample image and the reconstructed image by a preset error function, and set a threshold value based on the reference error value. The electronic device inputs an image possibly revealing a defect into the autoencoder and generates the reconstructed image corresponding to the image to be detected, and uses the preset error function to calculate the reconstruction error between the image and the reconstructed image, thereby determining whether the image being analyzed does reveal defects. When the reconstruction error is greater than the threshold value, a determination is made that a defect is revealed.

  • Patent number: 10955744
    Abstract: A method of determining a parameter of a pattern transfer process and device manufacturing methods are disclosed. In one arrangement, a method includes obtaining a detected representation of radiation redirected by a structure. The structure is a structure formed by applying a pattern processing to a pattern transferred to an earlier formed structure by a pattern transfer process. The pattern processing is such as to remove one or more selected regions in a horizontal plane of the earlier formed structure to form a pattern in the horizontal plane. The pattern is defined by a unit cell that is mirror symmetric with respect to an axis of mirror symmetry. An asymmetry in the detected representation is determined. The determined asymmetry in the detected representation is used to determine a parameter of the pattern transfer process.
