Abstract:
The invention relates to a field effect transistor structure, an associated semiconductor storage cell, and a corresponding production method. A diode-doping area (4) within a semiconductor substrate (1) is embodied with a field effect transistor structure (S/D, 3, K) while an electrically conducting diode-connecting layer (5) connects a control layer (3) of the field effect transistor structure to the diode-doping area (4) so as to create a diode (D), whereby excess charge carriers (L) in the semiconductor substrate (1) can be eliminated such that an undesired body effect is prevented.
Abstract:
The invention relates to an integrated strip conductor arrangement (12) consisting of several strip conductors (LB1 - LB3) crossing over each other at two overcrossing sections (20, 24), thereby ensuring an even flow of current in all three strip conductors, even at high frequencies.
Abstract:
According to the invention, a trench capacitor is formed inside a trench (30) that is arranged inside a substrate (20). The trench (30) is filled with a conductive trench filling (50) that serves as an inner capacitor electrode. An epitaxial layer (75) is grown on the lateral wall of the trench (30) on the substrate (20). A buried contact (60) is arranged between the conductive trench filling (50) with the second intermediate layer (65) and the epitaxially grown layer (75). A dopant out-diffusion (80), which is formed while leading out from the buried contact (60), is arranged inside the epitaxially grown layer (75). The epitaxially grown layer (75) enables the dopant out-diffusion (80) to be further removed from a selection transistor (10) located next to the trench whereby permitting the prevention of short channel effects in the selection transistor (10).
Abstract:
A memory cell (400) comprises trench filled with conductive material; selection transistor; connection (6) connecting the conductive material to selection transistor, the connection including vertical insulation collar; and lateral insulation collar of trench (5). The vertical insulation collar is connected to lateral insulation collar. The lateral insulation collar is configured laterally with respect to vertical insulation collar. Independent claims are also included for: (a) a semiconductor component with at least one memory cell, comprising a trench filler with a conductive material; a selection transistor; a connection; and a lateral insulation collar; and (b) manufacture of lateral insulation collar for a memory cell, comprising fabricating a bottle trench and filling the trench near the vertical wall; subsequently filling an upper, curved region of the trench with an insulator; and anisotropically etching the upper region of the trench to penetrate through the insulator.
Abstract:
An explanation is given of an integrated interconnect arrangement having a plurality of interconnects that cross over one another at two crossover sections. By virtue of this measure, it is possible to achieve a uniform current flow in all three interconnects even at very high frequencies.
Abstract:
Gate stacks (GS1-4) are applied to a gate dielectric (11) over the semiconductor substrate (10). A sidewall oxide (17) is formed on the gate stacks. A mask (12) is applied to the semiconductor structure, and is then structured. A contact doping (13) is implanted and self-adjusts to the sidewall oxide of the gate stack (GS1, GS2), in regions not covered by the mask
