  • Patent number: 11282754
    Abstract: A die shift correction method for use by a maskless exposure machine is applied to a die bonded to a substrate. The substrate has plural contact holes. The die has plural contact points each intended to be subjected to a light exposure in order to form a conductive contact portion connected to the corresponding contact hole. The correction method includes: obtaining the state information of the die by a first pre-scanning means, wherein the state information includes shape and location information; comparing the state information of the die against a reference state, and calculating compensation values with which to correct the reference state and thereby bring the reference state into conformity to the state information of the die; and calculating a compensation section for the light exposure according to the compensation values in order for each conductive contact portion to have an exposure pattern formed at the corresponding contact hole.

  • Patent number: 10459341
    Abstract: Embodiments of the present disclosure generally provide a digital lithography system that can process both large area substrates as well as semiconductor device substrates, such as wafers. Both the large area substrates and the semiconductor device substrates can be processed in the same system simultaneously. Additionally, the system can accommodate different levels of exposure for forming the features over the substrates. For example, the system can accommodate very precise feature patterning as well as less precise feature patterning. The different exposures can occur in the same chamber simultaneously. Thus, the system is capable of processing both semiconductor device substrates and large area substrates simultaneously while also accommodating very precise feature patterning simultaneous with less precise feature patterning.

  • Patent number: 8599541
    Abstract: An electronic apparatus includes a casing, a cap, and an access module. An accommodation space of the casing is used for accommodating a data storage apparatus, and the access module is disposed inside the accommodation space. The casing is formed with an opening at a position corresponding to an access unit, so that an external card is inserted in or pulled out through the opening. A terminal of the access module is pivoted on the casing. The cap is used for covering and thus sealing the accommodation space, so that the access module is arranged between the data storage apparatus and the cap. Thereby, the space is saved, and the access module and the data storage apparatus can be detached or assembled conveniently.
