  • Publication number: 20190355731
    Abstract: In some embodiments, a method for forming a semiconductor device is provided. The method includes forming a pad stack over a semiconductor substrate, where the pad stack includes a lower pad layer and an upper pad layer. An isolation structure having a pair of isolation segments separated in a first direction by the pad stack is formed in the semiconductor substrate. The upper pad is removed to form an opening, where the isolation segments respectively have opposing sidewalls in the opening that slant at a first angle. A first etch is performed that partially removes the lower pad layer and isolation segments in the opening so the opposing sidewalls slant at a second angle greater than the first angle. A second etch is performed to round the opposing sidewalls and remove the lower pad layer from the opening. A floating gate is formed in the opening.

  • Publication number: 20190229123
    Abstract: A semiconductor device includes a non-volatile memory and a logic circuit. The non-volatile memory includes a stacked structure comprising a first insulating layer, a floating gate, a second insulating layer, a control gate and a third insulating layer stacked in this order from a substrate; an erase gate line; and a word line. The logic circuit includes a field effect transistor comprising a gate electrode. The word line includes a protrusion, and a height of the protrusion from the substrate is higher than a height of the erase gate line from the substrate. The word line and the gate electrode are formed of polysilicon.

  • Publication number: 20190157281
    Abstract: A semiconductor device includes a non-volatile memory. The non-volatile memory includes a first dielectric layer disposed on a substrate, a floating gate disposed on the dielectric layer, a control gate, a second dielectric layer disposed between the floating gate and the control gate, sidewall spacers disposed on opposing sides of a stacked structure including the floating gate, the second dielectric layer and the control gate, and an erase gate and a select gate disposed on sides of the stacked structure, respectively. An upper surface of the erase gate and one of the sidewall spacers in contact with the erase gate form an angle ?1 at a contact point of the upper surface of the erase gate and the one of the sidewall spacers, where 90°<?1<115° measured from the upper surface of the erase gate.
