List of common concepts and definitions for Photodiodes.
Opto-die refers to the semiconductor chips used in optoelectronic devices, which are components that convert electrical signals into light or vice versa. These chips are the heart of devices such as LEDs, laser diodes, photodiodes, and other light-emitting or light-sensitive components.
Epitaxial wafers, commonly referred to as epi wafers, are semiconductor wafers onto which a thin layer of semiconductor material has been deposited in a crystalline phase. This process builds up layers of material or epi structures with precise control over the impurities and the thickness of the layers, which is essential for fabricating optoelectronic or photonic semiconductor devices.
Fully processed wafers are semiconductor wafers that have undergone all the necessary fabrication steps to become functional semiconductor devices. These include doping, etching, deposition of various materials, and the application of photolithographic patterns.
Marktech Optoelectronics distinguishes itself through its ability to provide highly customized solutions across the spectrum of semiconductor materials and optoelectronic components. By offering opto-die, epi wafers, and fully processed wafers tailored to specific needs, Marktech caters to a broad client base, including industries where precision, reliability, and innovation are critical. Their expertise in both standard and custom designs allows for flexibility and creativity in addressing complex engineering challenges.
The success of any optoelectronic component or assembly is predicated on the quality of the chip. Marktech’s vast emitter chips range from deep UV at 275nm to SWIR (Short Wavelength Infrared) at 3000nm. In the blue, green, or white range, Marktech features CREE LED-manufactured LED chips. CREE LED delivers superior price/performance for high-intensity LEDs in low- and high-power applications. Marktech, as a solutions provider for CREE LED, offers materials and customized packaging options, including TO-metal-can packaging with customized optics and COB (Chip On Board) arrays.
In addition to materials on the emission side, Marktech offers a wide variety of detector chips. These include Silicon types ranging from 365nm to 1100nm and InGaAs types ranging from 600nm to 2600nm.
Although Marktech offers one of the largest selections and range of emitters and detectors in the industry, the ever-increasing technology advancements and applications often require a custom solution to be developed.
Marktech provides custom material solutions for both the visible and infrared spectrums in emission and detection.
Current standard “visible” emitter sizes range from 170um x 170um to 1930um x 1930um and from ~450nm to 730nm. Marktech’s tight binning can provide uniform color and output characteristics to optimize the application and match photodetectors, providing process-controlled, uniform product solutions.
Marktech’s standard “infrared” die is available in a variety of footprints, from small 280um x 280um energy-efficient types to large 1066um x 1066um high-power types used in various illumination applications. The standard wavelength range is from ~730nm to 980nm. These chips exhibit some of the highest power output commercially available on the market. Material types include GaAs and GaAlAs.
Point Source Emitters – 570nm to 880nm
Marktech’s Point Source Emitter die is a unique LED chip that produces a well-defined light pattern similar to a “point.” Combined with high-quality grade glass lenses, these chips produce an extremely narrow, near-parallel radiation pattern. This unobstructed, radiated beam pattern is made possible by creating a unique, defined active area and relocating the topside electrode. By eliminating the “dark spot” typically associated with the center of conventional LEDs, the point source LED yields superior results in critical sensing applications. Still, it can also be used in visible devices such as range finder scopes.
Marktech currently offers these chips with aperture sizes ranging from 10um in diameter to 300um. The die can be customized to meet your specific application.
Marktech LED display chips utilize monolithic technology to create multi-segmented chips, enabling the creation of numbers, letters, and symbols. Each segment can be individually addressable and operate at drive currents less than 5mA, making them ideally suitable for portable optical instruments, range finders, and applications that require long battery life and small emission areas.
Marktech standard detector materials are available in either Si or InGaAs types. The P and N epitaxial layers of the wafer materials can be optimized for specific customer specifications and desired characteristics, including Minimum Reflection, Low Dark Current, Minimum Series Resistance, Low Capacitance, Fast Response, High Gain/Sensitivity, Low Cross Talk, and more. Current sizes for Silicon type die range from 0.2mm active area to 15.0mm active area. Current standard sizes for Indium Gallium Arsenide type detector die range from 0.1mm diameter active area to 3.0mm diameter active area. The detectors can be packaged in various packages, from metal cans and standard 3mm and 5mm plastic packages to surface mounts or virtually any custom package assembly.
