Extended length trench resistor and capacitor.

摘要

A resistive element (10) and method for constructing the same is provided which includes a trench (12) formed in an underlying layer (14). A resistive layer (26) is formed within trench (12) and separated therefrom by an insulating layer (24). Tabs (30,32) may be formed at the ends (44,46) of resistive layer (26). An insulating region (38) may be formed in either void area (27) or (36). A capacitance may also be realized where the underlying layer (14) is a conductor thereby enclosing a dielectric (insulating layer (24)) between itself and resistive layer (26).
