  • Patent number: 12159787
    Abstract: In a pattern formation method, a photoresist layer is formed over a substrate by combining a first precursor and a second precursor in a vapor state to form a photoresist material. The first precursor is an organometallic having a formula MaRbXc, where M is one or more selected from the group consisting of Sn, Bi, Sb, In, and Te, R is an alkyl group that is substituted by different EDG and/or EWG, X is a halide or sulfonate group, and 1?a?2, b?1, c?1, and b+c?4. The second precursor is water, an amine, a borane, and/or a phosphine. The photoresist material is deposited over the substrate, and selectively exposed to actinic radiation to form a latent pattern, and the latent pattern is developed by applying a developer to the selectively exposed photoresist layer to form a pattern.

  • Patent number: 11726747
    Abstract: In some embodiments, a method for generating a random bit is provided. The method includes generating a first random bit by providing a random number generator (RNG) signal to a magnetoresistive random-access memory (MRAM) cell. The RNG signal has a probability of about 0.5 to switch the resistive state of the MRAM cell from a first resistive state corresponding to a first data state to a second resistive state corresponding to a second data sate. The first random bit is then read from the MRAM cell.
