Abstract: For sensing pH of a fluid, a heating apparatus of a semiconductor die controls a temperature of the fluid to a first temperature. A first voltage of a gate of a floating gate transistor of the semiconductor die is measured while the temperature of the fluid is at the first temperature. Also, the heating apparatus controls the temperature of the fluid to a second temperature that is different than the first temperature. A second voltage of the gate is measured while the temperature of the fluid is at the second temperature. The pH of the fluid is determined based on the first and second voltages, the first temperature and the second temperature.

Abstract: In a frictionless handoff of audio content playing, a client device listens for ultrasonic audio. The client hears a playing of a modified audio content by another client device, which includes audio content and an ultrasonic audio quick response (QR) code overlaid on the audio content. The ultrasonic audio QR code includes location information corresponding to a location in the audio content. The client device extracts the ultrasonic audio QR code from the modified audio content. After determining that the playing of the modified audio content has stopped, the client device receives a command to resume playing of the audio content on the client device. In, response to the command, the client device retrieves location information in a last extracted ultrasonic audio QR code and plays the audio content starting at a location in the audio content corresponding to the location information in the last extracted ultrasonic audio QR code.

Abstract: Curing of a passivation layer applied to the surface of a ferroelectric integrated circuit so as to enhance the polarization characteristics of the ferroelectric structures. A passivation layer, such as a polyimide, is applied to the surface of the ferroelectric integrated circuit after fabrication of the active devices. The passivation layer is cured by exposure to a high temperature, below the Curie temperature of the ferroelectric material, for a short duration such as on the order of ten minutes. Variable frequency microwave energy may be used to effect such curing. The cured passivation layer attains a tensile stress state, and as a result imparts a compressive stress upon the underlying ferroelectric material. Polarization may be further enhanced by polarizing the ferroelectric material prior to the cure process.

The wafer moves under the droplet-on-demand sites in a first direction to form the first photoresist sublayer. A portion of the solvents in the first photoresist sublayer is removed. A second photoresist sublayer is formed on the first photoresist sublayer using the droplet-on-demand sites while the wafer is at a second temperature to attain less than 10 percent thickness non-uniformity in the combined first and second photoresist sublayers. The wafer moves under the droplet-on-demand sites in a second direction for the second photoresist sublayer, opposite from the first direction.
