Methods and apparatus for implementing variable, e.g., tunable, 3 terminal capacitance devices are described. In various embodiments vertical control pillars spaced apart from one another extend in a well having an opposite polarity than the polarity of the control pillars. The control pillars are arranged in a line that extends parallel to but between a deep trench gate and a well pickup. By varying the voltage applied to the control pillars the size of the depletion zone around the pillars can be varied resulting in a change in capacitance between the trench gate and pickup terminal connected to the well pickup. The generally vertical nature of the control pillars facilities control over a wide range of voltages while allowing for manufacturing using common semiconductor manufacturing steps making the device easy to implement on a chip with other semiconductor devices.
