  • Patent number: 11171035
    Abstract: Techniques of fabricating shallow trench isolation structures that reduce or minimize the number of trench cones during the formation of shallow trenches. The disclosed techniques introduce separate etch steps for etching shallow trenches with small feature dimensions and for etching shallow trenches with large feature dimensions. As an example, the disclosed techniques involve etching a first shallow trench in a first region of a substrate with a first etching parameter, and etching a second shallow trench in a second region of a substrate with a second etching parameter different from the first etching parameter. Among other things, the etching parameter may include an etching selectivity ratio of silicon to an etch retardant that contributes to cone formations. Because of the separate etch steps, the disclosed techniques allow the sidewall slopes between the first and second shallow trenches to be within a few degrees of deviation.

  • Patent number: 11166399
    Abstract: An electronic module with an integrated electromagnetic shield using surface mount shield wall components has been disclosed. Each surface mount shield wall component provides side shielding of the circuitry within the overmolded electronic module and provides an exposed conductive shield wall section to which a top conductive shield can be applied. By including the shield structure as part of the overmolded electronic module, the need for a separate shield and separate process steps for installing the separate shield can be eliminated. Each surface mount shield wall component comprises a non-conductive portion that provides stability during a reflow soldering process, but at least a sacrificial portion of the non-conductive portion can be removed to reduce the amount of area occupied by the overmoldable shield structure.

  • Patent number: 11152393
    Abstract: A semiconductor device using an SOI (Silicon On Insulator) substrate, capable of preventing malfunction of MISFETs (Metal Insulator Semiconductor Field Effect Transistor) and thus improving the reliability of the semiconductor device. Moreover, the parasitic resistance of the MISFETs is reduced, and the performance of the semiconductor device is improved. An epitaxial layer formed on an SOI layer above an SOI substrate is formed to have a large width so as to cover the ends of the upper surface of an isolation region adjacent to the SOI layer. By virtue of this, contact plugs of which formation positions are misaligned are prevented from being connected to a semiconductor substrate below the SOI layer. Moreover, by forming the epitaxial layer at a large width, the ends of the SOI layer therebelow are prevented from being silicided. As a result, increase in the parasitic resistance of MISFETs is prevented.
