Radiation Controlled Devices TRIZ Cases

Asymmetrical microlenses align optical axes with photodiodes to resolve non-uniform light distribution caused by varying incident angles.

A photosensitive capacitor pixel uses a coaxial conductive layer and dielectric to generate image signals via the photoelectric effect.

Lateral edge termination structures in silicon carbide avalanche photodiodes isolate the active detection region from peripheral charge generation.

Through-oxide vias link image sensor and digital signal processing dies via selective etching, reducing bond pad area and manufacturing complexity.

High-resistance substrates manage charge carrier depletion to reduce after pulsing and improve quantum yield in avalanche radiation detectors.

Multilayer band gap transition reduces current flow resistance and prevents Schottky layer peeling during wire bonding for reliable multi-wavelength detection.

Frontside and backside photodetector pairs reduce pixel-to-pixel color crosstalk caused by grid distortions during wafer thinning.

A TDI image sensor uses a segmented charge transport layer with separate gates to move electrical charges between photo-sensitive elements.

Pulsed light annealing crystallizes the buffer layer below 350°C, preventing thermal damage to the underlying CMOS substrate.

An energy conversion layer shifts blue photons to longer wavelengths, resolving spectral mismatch and boosting detection capability for high-energy light.

Vertical electrodes transfer charge through substrate zones, reducing crosstalk and image distortion in compact global shutter pixels.

A split-gate pixel architecture uses conditional reset and multi-bit sampling to convert photodetector signals efficiently.

Separating data and scan lines into distinct metal layers reduces line capacitance by 48%, improving TFT array yield and image quality.

A stacked image sensor uses a nested color filter array to direct mixed light spectra toward the photoelectric device.

Isolation structures suppress crosstalk and temperature-dependent signal variations in imaging devices.

Segmented pixel regions with insulating and metal barriers suppress secondary photon penetration, enhancing sensitivity while minimizing crosstalk noise.

Dividing the first electronic region into multiple segments increases charge accumulation capacity, allowing higher source-drain voltage without saturation.
