Abstract: The present invention relates to bipolar junction transistors (BJTS). The collector region of each BJT is located in a semiconductor substrate surface and adjacent to a first shallow trench isolation (STI) region. A second STI region is provided, which extends between the first STI region and the collection region and undercuts a portion of the active base region with an undercut angle of not more than about 90°. For example, the second STI region may a substantially triangular cross-section with an undercut angle of less than about 90°, or a substantially rectangular cross-section with an undercut angle of about 90°. Such a second STI region can be fabricated using a porous surface section formed in an upper surface of the collector region.

Abstract: The present invention pertains to an apparatus for evaluating the signal strength from the pH sensor to determine whether the sensor is hydrated sufficiently to accurately measure pH. This is accomplished by utilizing circuitry that periodically sends a low voltage signal to a suitable pH sensor and then receiving the resulting waveforms which are analyzed by a processing receiver. The electrical connection between a suitable pH sensor and hydration monitoring circuitry is generally hard wired. In one embodiment, a processing receiver is coupled with the hydration monitoring circuitry as a single apparatus. In a second embodiment, the processing receiver can be independent and located remote from the hydration monitoring circuitry. In this embodiment, the hydration monitoring circuitry and the processing receiver are electrically connected using either hard wired techniques or wireless technology. In addition, the processing receiver can include data recording capability.

Abstract: The present invention is a system for monitoring a patient's breath chemistry comprising a plurality of components, including a self-condensing pH sensor distally mounted on a catheter, a transmitter with hydration sensing circuitry for the pH sensor, and processing receiver/data recorder. A specially designed self-condensing pH sensor is located on the distal end of a tubular catheter which is designed to be inserted into the patient's airway. Monitoring of a patient's breath pH is accomplished by using the miniaturized self-condensing pH sensor, providing for real-time monitoring of patient airway pH values. The self-condensing pH sensor comprises a multi-tubular design with the catheter tubular member housing a silver chloride reference element, an ion conducting path, and an antimony sensor element isolated within an inner tubular member that is co-linearly or coaxially configured with the outer catheter tubular member.
