A magnetic switch assembly for hearing devices designed for remote activation by the user is highly miniaturized with a self-contained latching mechanism. The switch is activated and deactivated by the user via a hand-held magnet placed in proximity to the hearing device. The switch assembly includes a miniature reed switch and a miniature latching magnet affixed directly to one of the reeds or the associated lead wire. Direct attachment minimizes the air gap between the latching magnet and a reed thus enabling latching with only an extremely small magnet. The latching magnet produces a magnetic field of adequate strength to hold the reeds together in electrical contact after the air gap between the reeds is closed by the user's placement of the external hand-held magnet in proximity thereto. But the latching magnet's field is of inadequate strength for unaided closure of the air gap between the reeds. Consequently, once the reeds are closed the latching magnet prevents separation thereof until the reeds are exposed to an external magnetic field of opposite polarity and sufficient strength to overcome the field produced by the latching magnet.

The present invention is directed to a method of forming an FeRAM integrated circuit, which includes performing a capacitor stack etch to define the FeRAM capacitor. The method comprises etching a PZT ferroelectric layer with a high temperature BCl3 etch which provides substantial selectivity with respect to the hard mask. Alternatively, the PZT ferroelectric layer is etch using a low temperature fluorine component etch chemistry such as CHF3 to provide a non-vertical PZT sidewall profile. Such a profile prevents conductive material associated with a subsequent bottom electrode layer etch from depositing on the PZT sidewall, thereby preventing leakage or a “shorting out” of the resulting FeRAM capacitor.

Gaps between circumferentially and radially spaced diffusers at their exits are eliminated. With this arrangement, uniform flow distribution of the fuel / air, velocity and temperature is provided at the catalyst inlet.

A complementary source follower circuit has an N-channel type transistor and a P-channel transistor. The threshold voltage of each transistor is independently controlled by a back bias voltage control circuit so that the input voltage and the output voltage relationship can be made linear without the use of an additional circuit such as a level shifting circuit. Also, power consumption can be reduced when the circuit is in standby mode by using the back bias voltage control circuit to achieve non-linearity. A back bias voltage control circuit can also be used to control the threshold voltage of a transistor in series with a resistance load to reduce power usage.
