  • Patent number: 11948954
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.

  • Patent number: 10147470
    Abstract: A semiconductor memory device includes a charge storage element, a read transistor, and a write transistor. The charge storage element is for preserving a first data voltage. The read transistor has a first terminal coupled to the charge storage element, a second terminal coupled to a read bit line, and a control terminal coupled to a read word line. The write transistor has a first terminal coupled to the first terminal of the read transistor, a second terminal coupled to a write bit line, and a control terminal coupled to a write word line. The semiconductor memory device is able to perform a read operation and a write operation to the charge storage element simultaneously through the read transistor and the write transistor.

  • Publication number: 20050097483
    Abstract: Disclosed are a verifier and method for dimension rule check. By checking all basic units in a database and the basic units related to the bulk according to predefined spacing rules, a warning set within the database can be distinguished from those basic units checked by spacing rules. The warning set can specify where or what may be ignored by the spacing rules and should be concerned to refine the spacing rules.
