  • Patent number: 8815676
    Abstract: Methods of forming vertical nonvolatile memory devices may include forming an electrically insulating layer, which includes a composite of a sacrificial layer sandwiched between first and second mold layers. An opening extends through the electrically insulating layer and exposes inner sidewalls of the first and second mold layers and the sacrificial layer. A sidewall of the opening may be lined with an electrically insulating protective layer and a first semiconductor layer may be formed on an inner sidewall of the electrically insulating protective layer within the opening. At least a portion of the sacrificial layer may then be selectively etched from between the first and second mold layers to thereby define a lateral recess therein, which exposes an outer sidewall of the electrically insulating protective layer.

  • Patent number: 8637959
    Abstract: The invention discloses a vertical parasitic PNP transistor in a BiCMOS process and manufacturing method of the same, wherein an active region is isolated by STIs. The transistor includes a collector region, a base region, an emitter region, pseudo buried layers, and N-type polysilicon. The pseudo buried layers, formed at the bottom of the STIs located on both sides of the collector region, extend laterally into the active region and contact with the collector region, whose electrodes are picked up through making deep-hole contacts in the STIs. The N-type polysilicon is formed on the base region and contacts with it, whose electrodes are picked up through making metal contacts on the N-type polysilicon. The transistors can be used as output devices in high-speed and high-gain circuits, efficiently reducing the transistors area, diminishing the collector resistance, and improving the transistors performance. The method can reduce the cost without additional technological conditions.
