    摘要: A semiconductor device having memory cells. Each of the memory cells has a word gate formed over a semiconductor substrate with a first gate insulating layer interposed, an impurity layer, and first and second control gates in the shape of sidewalls. The first and second control gates adjacent to each other with the impurity layer interposed are connected to a common contact section. The common contact section includes a first contact conductive layer, a second contact conductive layer, and a pad-shaped third contact conductive layer. The third contact conductive layer is formed over the first and second contact conductive layers.

    摘要: A method of manufacturing a semiconductor device that has a high-breakdown-voltage transistor, a low-voltage driving transistor and a MONOS type memory transistor includes a step of forming a stack film that includes at least an oxide silicon layer and a nitride silicon layer over a high-breakdown-voltage transistor forming region where the high-breakdown-voltage transistor is formed, a low-voltage driving transistor forming region where the low-voltage driving transistor is formed and a MONOS type memory transistor forming region where the MONOS type memory transistor is formed in a semiconductor layer, a step of removing the stack film formed in a first gate insulating layer forming region of the high-breakdown-voltage transistor and a step of forming a first gate insulating layer in the high-breakdown-voltage transistor forming region by thermal oxidation. The method also includes a step of removing the stack film formed in the low-voltage driving transistor forming region, a step of forming a second gate insulating layer in the low-voltage driving transistor forming region, a step of forming gate electrodes in the high-breakdown-voltage transistor forming region, the low-voltage driving transistor forming region and the MONOS type memory transistor forming region and a step of forming source/drain regions in the high-breakdown-voltage transistor forming region, the low-voltage driving transistor forming region and the MONOS type memory transistor forming region.

    摘要: A semiconductor device of the present invention includes memory cells. Each of the memory cells includes a word gate formed over a semiconductor substrate with a second gate insulating layer interposed therebetween, an impurity layer, and first and second control gates in the shape of sidewalls. The first and second control gates adjacent to the impurity layer interposed therebetween is connected with a common contact section. The common contact section includes a contact conductive layer, a stopper insulating layer, and a cap insulating layer. The contact conductive layer is continuous with the first and second control gates. The cap insulating layer is formed at least over the stopper insulating layer.
