  • Publication number: 20240379418
    Abstract: A disclosed method of fabricating a semiconductor structure includes forming a first conductive pattern over a substrate, with the first conductive pattern including a first conductive line and a second conductive line. A barrier layer may be conformally formed over the first conductive line and the second conductive line of the first conductive pattern. An insulating layer may be formed over the barrier layer. The insulating layer may be patterned to form openings between conductive lines of the first conductive pattern a second conductive pattern may be formed in the openings. The second conductive pattern may include a third conductive line is physically separated from the first conductive pattern by the barrier layer. The presence of the barrier layer reduces the risk of a short circuit forming between the first and second conductive patterns. In this sense, the second conductive pattern may be self-aligned relative to the first conductive pattern.

  • Publication number: 20240373646
    Abstract: A planar insulating spacer layer can be formed over a substrate, and a combination of a semiconducting material layer, a thin film transistor (TFT) gate dielectric layer, and a gate electrode can be formed over the planar insulating spacer layer. A dielectric matrix layer is formed thereabove. A source-side via cavity and a drain-side via cavity can be formed through the dielectric matrix layer over end portions of the semiconducting material layer. Mechanical stress can be generated between the end portions of the semiconducting material layer by changing a lattice constant of end portions of the semiconducting material layer. The mechanical stress can enhance the mobility of charge carriers in a channel portion of the semiconducting material layer.

  • Publication number: 20240337951
    Abstract: In a method of manufacturing a photo mask for lithography, circuit pattern data are acquired. A pattern density, which is a total pattern area per predetermined area, is calculated from the circuit pattern data. Dummy pattern data for areas having pattern density less than a threshold density are generated. Mask drawing data is generated from the circuit pattern data and the dummy pattern data. By using an electron beam from an electron beam lithography apparatus, patterns are drawn according to the mask drawing data on a resist layer formed on a mask blank substrate. The drawn resist layer is developed using a developing solution. Dummy patterns included in the dummy pattern data are not printed as a photo mask pattern when the resist layer is exposed with the electron beam and is developed.

  • Publication number: 20240145533
    Abstract: A high voltage transistor may include a stepped dielectric layer between a field plate structure and a channel region of the high voltage transistor in a substrate. The stepped dielectric layer may increase the breakdown voltage of the high voltage transistor by reducing the electric field strength near the drain region of the high voltage transistor. In particular, a portion of the stepped dielectric layer near the drain region includes a thickness that is greater relative to a thickness of another portion of the stepped dielectric layer near the gate structure. The increased thickness near the drain region provides increased electric field suppression near the drain region (which operates at high voltages). In this way, the stepped dielectric layer enables the high voltage transistor described herein to achieve higher breakdown voltages without increasing the distance between the gate structure and the drain region of a high voltage transistor.
