Abstract:
A bio-fluid sensor is formed by depositing polyimide on a glass substrate. Gold and platinum are deposited on the polyimide and patterned to form fluid sensing electrodes, signal traces, and a temperature sensor. The fluid sensor is then fixed to a flexible tape and peeled off of the glass substrate.

An integrated circuit (IC) package includes a die pad and an IC die secured on the die pad. The IC die had outer edges aligned with outer edges of the die pad. An encapsulating material body surrounds the die pad and IC die. Leads extend outwardly from the encapsulating material body and are coupled to the IC die. Each lead has an upper surface coplanar with an upper surface of the IC die. The die pad has a lower surface exposed through the encapsulating material body, and has a thickness greater than a thickness of each of the plurality of leads.

Each mask image may be in a corresponding different mask sector. The method may also include performing a series of exposures with the rotatably alignable photolithography mask at different rotational alignments with respect to the semiconductor wafer so that the different mask images produce at least one working semiconductor wafer sector, and at least one non-working semiconductor wafer sector.
Abstract:
A miniature oxygen sensor makes use of paramagnetic properties of oxygen gas to provide a fast response time, low power consumption, improved accuracy and sensitivity, and superior durability. The miniature oxygen sensor disclosed maintains a sample of ambient air within a micro-channel formed in a semiconductor substrate. O2 molecules segregate in response to an applied magnetic field, thereby establishing a measureable Hall voltage. Oxygen present in the sample of ambient air can be deduced from a change in Hall voltage with variation in the applied magnetic field. The magnetic field can be applied either by an external magnet or by a thin film magnet integrated into a gas sensing cavity within the micro-channel. A differential sensor further includes a reference element containing an unmagnetized control sample. The miniature oxygen sensor is suitable for use as a real-time air quality monitor in consumer products such as smart phones.

Abstract:
A semiconductor die includes a chemical sensor, a digital to analog converter, and microcontroller formed therein. The chemical sensor detects the presence of a chemical and outputs an analog signal to the digital to analog converter. The analog to digital converter converts the analog signal to a digital signal. The analog to digital converter outputs the digital signal to the microcontroller. Microcontroller calculates a value of the concentration of the selected chemical.
Abstract:
A universal electrochemical micro-sensor can be used either as a biosensor or an environmental sensor. Because of its small size and flexibility, the micro-sensor is suitable for continuous use to monitor fluids within a live subject, or as an environmental monitor. The micro-sensor can be formed on a reusable glass carrier substrate. A flexible polymer backing, together with a set of electrodes, forms a reservoir that contains an electrolytic fluid chemical reagent. During fabrication, the glass carrier substrate protects the fluid chemical reagent from degradation. A conductive micromesh further contains the reagent while allowing partial exposure to the ambient biological or atmospheric environment. The micromesh density can be altered to accommodate fluid reagents having different viscosities. Flexibility is achieved by attaching a thick polymer tape and peeling away the micro-sensor from the glass carrier substrate. The final structure is thereby transferred to the polymer tape, providing a flexible product.
