摘要:
Methods and systems for improved matching of on-chip capacitors may comprise a semiconductor die with an on-chip capacitor comprising one or more metal layers. The on-chip capacitor may comprise interdigitated electrically coupled metal fingers. The electrically coupled metal fingers may be arranged symmetrically in the semiconductor die to compensate for non-uniformities in the one or more metal layers. The metal fingers may be arranged with radial symmetry. Metal fingers in a first metal layer may be electrically coupled to metal fingers in a second metal layer. An orientation of metal fingers may be alternated when coupling metal fingers in a plurality of metal layers. The metal fingers may be coupled at the center or the outer edge of the on-chip capacitor. The on-chip capacitor may be configured in a plurality of symmetric sections wherein a boundary between each of the plurality of sections is configured in a zig-zag pattern.

A semiconductor device (2) includes a semiconductor substrate (12) having a surface (13) formed with a first recessed region (20). A first dielectric material (60) is deposited in the first recessed region and formed with a second recessed region (76), and a second dielectric material (100) is grown over the first dielectric material to seal the second recessed region.

摘要:
A method of making a semiconductor device (10) having a low permittivity region (24) includes forming a first layer (30/42) over a surface of a trench (20), and etching through an opening (70) in the first layer that is smaller than a width (W2) of the trench to remove a first material (38) from the trench. A second material (44) is deposited to plug the opening to seal an air pocket (40) in the trench. The low permittivity region features air pockets with a high volume because the small size of the opening allows the second material to plug the trench without accumulating significantly in the trench.
