  • Patent number: 10199412
    Abstract: This disclosure describes optoelectronic modules that include an image sensor having at least two regions separated optically from one another by a wall. The wall can include a bridge portion that extends over the image sensor and further can include a cured adhesive portion, part of which is disposed between a lower surface of the bridge portion and an upper surface of the image sensor. Various techniques are described for fabricating the modules so as to help prevent the adhesive from contaminating sensitive regions of the image sensor. The wall can be substantially light-tight so as to prevent undesired optical cross-talk, for example, between a light emitter located to one side of the wall and a light sensitive region of the image sensor located to the other side of the wall.

  • Patent number: 10134895
    Abstract: The presence of a facet or a void in an epitaxially grown crystal indicates that crystal growth has been interrupted by defects or by certain material boundaries. Faceting can be suppressed during epitaxial growth of silicon compounds that form source and drain regions of strained silicon transistors. It has been observed that faceting can occur when epitaxial layers of certain silicon compounds are grown adjacent to an oxide boundary, but faceting does not occur when the epitaxial layer is grown adjacent to a silicon boundary or adjacent to a nitride boundary. Because epitaxial growth of silicon compounds is often necessary in the vicinity of isolation trenches that are filled with oxide, techniques for suppression of faceting in these areas are of particular interest. One such technique, presented herein, is to line the isolation trenches with SiN to provide a barrier between the oxide and the region in which epitaxial growth is intended.

  • Patent number: 9997602
    Abstract: A semiconductor device includes transistor cells and enhancement cells. Each transistor cell includes a body zone that forms a first pn junction with a drift structure. The transistor cells may form, in the body zones, inversion channels when a first control signal exceeds a first threshold. The inversion channels form part of a connection between the drift structure and a first load electrode. A delay unit generates a second control signal which trailing edge is delayed with respect to a trailing edge of the first control signal. The enhancement cells form inversion layers in the drift structure when the second control signal falls below a second threshold lower than the first threshold. The inversion layers are effective as minority charge carrier emitters.

  • Patent number: 9935124
    Abstract: Split memory cells can be provided within an alternating stack of insulating layers and word lines. At least one lower-select-gate-level electrically conductive layers and/or at least one upper-select-level electrically conductive layers without a split memory cell configuration can be provided by limiting the levels of separator insulator structures within the levels of the word lines. At least one etch stop layer can be formed above at least one lower-select-gate-level spacer material layer. An alternating stack of insulating layers and spacer material layers is formed over the at least one etch stop layer. Separator insulator structures are formed through the alternating stack employing the etch stop layer as a stopping structure. Upper-select-level spacer material layers can be subsequently formed. The spacer material layers and the select level material layers are formed as, or replaced with, electrically conductive layers.

  • Patent number: 9935123
    Abstract: An alternating stack of sacrificial material layers and insulating layers is formed over a substrate. Replacement of sacrificial material layers with electrically conductive layers can be performed employing a subset of openings. A predominant subset of the openings is employed to form memory stack structures therein. A minor subset of the openings is employed as access openings for introducing an etchant to remove the sacrificial material layers to form lateral recesses and to provide a reactant for depositing electrically conductive layers in the lateral recesses. By distributing the access openings across the entirety of the openings and eliminating the need to employ backside trenches for replacement of the sacrificial material layers, the size and lateral extent of backside trenches can be reduced to a level sufficient to accommodate only backside contact via structures.
