摘要:
The invention relates to an SOI substrate which is provided with a recess that cuts through the silicon layer and the SiO2 layer (O). An upper part of said recess (V) which is located in the range of the silicon layer (S) has cylindrical shape with a horizontal first cross-section. A lower part of the recess (V) which is located in the range of the SiO2 layer (O), compared with the upper part of the recess (V), is bulged to such an extent that it has a cylindrical shape with a horizontal second cross-section that is larger than the first cross-section. A cylinder (Z) of an insulating material is provided in the recess (V). The horizontal cross-section of said cylinder corresponds to the first cross-section and the lower part thereof is located in the lower part of the recess (V). The dent laterally surrounds the lower part of the cylinder (Z). A conducting structure (L) is located in the dent and adjoins the silicon layer (S) and the silicon substrate (1) so that the channel zone of the MOS transistors is electrically connected to the silicon substrate.

A dynamic random access memory includes memory cells arranged in rows and columns on the substrate and a plurality of connecting pillars, each associated with a memory cell. A bit line extends above the main area of the substrate and connects to each memory cell of a column. A first word line connects a first set of alternate memory cells of a row by a first subset of the plurality of connecting pillars. The first word line includes first parts arranged offset relative to the first subset of connecting pillars. A strip-shaped second part extends above the main area and adjoins the first parts of the first word line. A second word line connects to a second set of alternate memory cells of the row by a second subset of the connecting pillars. The second word line includes first parts arranged between mutually adjacent first word lines and offset from the second subset of the connecting pillars. Both the first and second word lines thus overlap but do not cover the connecting pillars. A strip-shaped second part extends above the main area in the first direction and adjoins the first parts of the second word line. The second part is above the first word line and the bit line.

The memory cells each have a capacitor and a transistor. A storage node of the capacitor is arranged in a first depression formed in a substrate. A gate electrode of the transistor is arranged in a second depression at a first lateral surface of the second depression. The second depression is spaced apart from the first depression. An upper source/drain region of the transistor adjoins the storage node and the second depression. A lower source/drain region of the transistor is formed deeper in the substrate than the upper source/drain region and it adjoins the second depression.

A memory cell has a vertical MOS transistor which contains a first electrically insulated gate electrode and a second gate electrode. The second gate electrode is partially disposed in a trench whose sidewall is adjoined by the MOS transistor. The first gate electrode is disposed outside the trench and has a tip at an edge of the trench. The tip enables programming with a reduced current flow. The memory cell can be fabricated by self-aligning fabrication with an area requirement of six F2.

摘要:
A fin field-effect transistor has a substrate and a fin structure above the substrate, as well as a drain region and a source region outside the fin structure above the substrate. The fin structure serves as a channel between the source region and the drain region. The source and drain regions are formed once a gate has been produced.
