Mutech microsystems microAligner is a compact high value UV mask aligner designed for microfabrication applications.
It allows for easy fabrication of multilayer devices on a multitude of photoresists, with excellent exposure quality.
The easy to use, 7 inch touchscreen based control allows the user to align using the calibrated digital microscope and the X-Y-R micrometer based alignment stage.
The fully electronic wafer pressure and gap control allows for easy alignment and very high repeatability of the exposure conditions between processes.
microAligner is ideal for the fabrication of high level systems for research applications.
Main applications range from microfluidics, optics and biotechnology to microelectronic devices.
It provides the user with fast multilayer device fabrication capabilities thanks to its high resolution and high accuracy alignment.
We are also offering a dual microscope version of our mask aligner for rapid aligning of big photomasks.
With this option the operator has access to two video feeds on the screen in real time while aligning, allowing the user to easily align two fiducial marks at once, simplifying the alignment process.
A LED source allows for instant turn-on, excellent homogeneity, low divergence and very long life.
With the 100mm diameter UV aperture, you can expose up to 4" wafers with 5" photomasks.
The microAligner footprint is only 350x490 mm and weighs less than 20kg.
The wafer stage is electronically controlled with real time pressure sensing, allowing for excellent repeatability.
The digital microscope includes a 590nm coaxial yellow illumination and it is used from the screen.
We have managed to keep the prices low allowing you to have a better lab on a tight budget.
The μAligner is primarily controlled from its 7 inch capacitive touchscreen.
From here the user has access to all the controls of the machine, the microscope controls and video feed, exposure parameters, wafer stage controls and mask vacuum.You have access to a real time wafer Z position and wafer pressure signals to allow for maximum repeatability.
The wafer Z position is controlled with a big 60 mm rotary encoder for maximum control. The user controls the wafer alignment to the mask using the X-Y-R stage with the mechanical micrometers.
The microscope can be freely moved by the user around the photomask to look for alignment marks.
Our direct laser lithography system, the microLaser, allows the user to fabricate its own optical masks, offering an increased versatility.
The microAligner system, as a complementary tool of the microLaser, offers the possibility to work with 365 nm sensitive photoresists and high accuracy alignment capabilities to obtain high aspect ratio structures and a high throughput on the lithography process.
These possibilities make the microAligner and microLaser package the ultimate solution for the fast fabrication and development of multilayered device applications including biomedical, microfluidics and microelectronic devices.
