  • Publication number: 20240134410
    Abstract: The present disclosure discloses a memory access interface device. A clock generation circuit generates reference signals. A transmitter transmits an output command and address signal to a memory device according to the reference signals. A signal training circuit executes a training process in a training mode that includes steps outlined below. A training signal is generated such that the training signal is transmitted as the output command and address signal. The training signal and the data signal generated by the memory device are compared to generate a comparison result indicating whether the data signal matches the training signal. The comparison result is stored. The clock generation circuit is controlled to modify a phase of at least one of the reference signals to be one of a plurality of under-test phases to execute a new loop of the training process until all the under-test phases are trained.

  • Publication number: 20240136226
    Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.
