    Abstract: The present application is related to system and method for analyzing confidential data. Firstly, a first key is used to obtain a first analysis authorization for proceeding a first analysis responsive to an operational model in an encrypted cloud space with a connection of a network. Then, the result of the first analysis is verified. While the verifying of the operational model is pass, a second key is used to obtain a second analysis authorization for proceeding a second analysis responsive to an operational model without the connection of the network. Thereby, the cloud technique for analyzing data can be applied for analyzing confidential data.

  • Patent number: 11114538
    Abstract: A microelectronic transistor may be fabricated having an airgap spacer formed as a gate sidewall spacer, such that the airgap spacer is positioned between a gate electrode and a source contact and/or a drain contact of the microelectronic transistor. As the dielectric constant of gaseous substances is significantly lower than that of a solid or a semi-solid dielectric material, the airgap spacer may result in minimal capacitive coupling between the gate electrode and the source contact and/or the drain contact, which may reduce circuit delay of the microelectronic transistor.

  • Patent number: 10991290
    Abstract: Control methods of a channel setting module applied to a display panel are provided. The display panel has gate lines, source lines, and pixels. The pixels are arranged in matrix. The pixels disposed at the same row are electrically connected to the same gate line, and the pixels disposed at the same column are electrically connected to the same source line. The adoption of the channel setting module reduces the control signals required by the source lines. The channel setting module includes operational amplifiers and de-mux switches, and the control methods dynamically determine conduction states of the de-mux switches. The voltage outputs of the operational amplifiers are selectively outputted to the source lines, depending on conduction statuses of the de-mux switches. By applying the control methods, the interference between the source lines are reduced, and the instantaneous overshoots/undershoots of floating channels are depressed.

  • Patent number: 10923574
    Abstract: Techniques are disclosed for forming a transistor with one or more additional spacers, or inner-gate spacers, as referred to herein. The additional spacers may be formed between the gate and original spacers to reduce the parasitic coupling between the gate and the source/drain, for example. In some cases, the additional spacers may include air gaps and/or dielectric material (e.g., low-k dielectric material). In some cases, the gate may include a lower portion, a middle portion, and an upper portion. In some such cases, the lower and upper portions of the gate may be wider between the original spacers than the middle portion of the gate, which may be as a result of the additional spacers being located between the middle portion of the gate and the original spacers. In some such cases, the gate may approximate an I-shape, C-shape, -shape, ?-shape, L-shape, or ?-shape, for example.
