Abstract: To mitigate undesirable outcomes due to crosstalk in an ambient light sensor reading resulting from light emission from an electronic display, statistics may be gathered to determine and compensate for the crosstalk. For example, the ambient light sensor may detect ambient light levels while the electronic display is temporarily paused to reduce or eliminate crosstalk between the light produced by the electronic display and the ambient light sensor. However, the ambient light sensor may retain charge from a previous light emission, creating back-emission crosstalk. The ratio of back-emission to front-emission (e.g., present light emission) may not be linear, and the degree of nonlinearity may vary with pixel value, color component, display brightness, temperature, and so on. As the ambient light sensor is affected by back-emission, compensation for the nonlinearity between the front-emission and the back-emission may be obtained to estimate the crosstalk induced on the ambient light sensor.

Abstract: An instrumented substrate may provide a metrology platform for monitoring extreme ultraviolet (EUV) radiation in an image plane of a EUV lithography tool. The instrumented substrate may include in-band dosage sensors. The in-band dosage sensors may generate dosage measurements corresponding to the illumination which is in-band. The instrumented substrate may also include out-of-band dosage sensors and in-band scattered dosage sensors. The instrumented substrate may be housed within a front opening unified pod (FOUP) of a system.

Abstract: A readout circuit for an amplitude modulating sensor includes a first and second wavelength light source; an optical coupler coupled to receive a first light signal from the first wavelength light source and a second light signal from the second wavelength light source; a frequency selector that allows for the first light signal to pass to the amplitude modulating sensor; and a detector system coupled to the optical coupler to receive the first light signal and the second light signal after the first light signal is modulated by the amplitude modulating sensor and independently detect the two signals. The detector system generates electronic signals representing the modulated first light signal and the second light signal and removes a common mode signal of the modulated first light signal and the second light signal, removing common mode noise or attenuation in the modulated first light signal.

Abstract: A scanning microscope includes: a photodetector that detects light from a sample; a sampling circuit that samples an output signal of the photodetector; and a processor. The processor performs an operation including at least integration on a plurality of items of sampling data sampled by the sampling circuit, determines whether a result of the operation is noise or a signal, and generates pixel data based on a result of the operation and a result of the determination.

Abstract: In a signal processing circuit, an input terminal is configured to receive an analog signal output from an avalanche photodiode operating in Geiger mode. A comparison circuit outputs a signal based on a component exceeding a threshold among components a signal input to the comparison circuit. The adjustment circuit includes an AC coupling unit, a level shifter unit, and a reference value adjustment unit. The AC coupling unit establishes AC coupling between the input terminal and the comparison circuit. The level shifter unit adjusts the voltage of the signal input to the comparison circuit to a value lower than a reverse bias voltage applied to the avalanche photodiode. The reference value adjustment unit adjusts the reference value of the signal input to the comparison circuit.

Abstract: Methods and corresponding systems and apparatuses for time-aligning a first set of measurement samples captured by a first sensor to a second set of measurement samples captured by a second sensor. Each sensor captures samples at regular intervals corresponding to a respective sampling period. The sensors directly or indirectly measure at least one reference signal. Each reference signal includes a reference marker followed by a sequence of alignment pulses. In the case of multiple reference signals, the sequence of alignment pulses can differ, but the reference marker can be identical. In some implementations, time-alignment involves assigning a timestamp to a first alignment pulse in the first set of measurement samples, relative to the reference marker in the first set of measurement samples and assigning a second timestamp to a second alignment pulse in the second set of measurement samples, relative to the reference marker in the second set of measurement samples.
