  • Publication number: 20170263762
    Abstract: Provided are a low-cost semiconductor device manufacturing method and a semiconductor device made using the method. The method includes forming multiple body regions in a semiconductor substrate, forming multiple gate insulating layers and multiple gate electrodes in the body region; implementing a blanket ion implantation in an entire surface of the substrate to form a low concentration doping region (LDD region) in the body region without a mask, forming a spacer at a side wall of the gate electrode, and implementing a high concentration ion implantation to form a high concentration source region and a high concentration drain region around the LDD region. According to the examples, devices have favorable electrical characteristics and at the same time, manufacturing costs are reduced. Since, when forming high concentration source region and drain regions, tilt and rotation co-implants are applied, an LDD masking step is potentially omitted.

  • Publication number: 20170263727
    Abstract: A lateral bipolar transistor includes trench emitter and trench collector regions to form ultra-narrow emitter regions, thereby improving emitter efficiency. The same trench process is used to form the emitter/collector trenches as well as the trench isolation structures so that no additional processing steps are needed to form the trench emitter and collector. In embodiments of the present invention, the trench emitter and trench collector regions may be formed using ion implantation into trenches formed in a semiconductor layer. In other embodiments, the trench emitter and trench collector regions may be formed by out-diffusion of dopants from heavily doped polysilicon filled trenches.
