Introduction

Micromanipulators from Imina Technologies find useful in a myriad of applications that require precision and deftness at micro and nanoscale. There are several cases in the optical microscopy field that get benefited from Imina Technologies miBot nanomanipulators.

Imina Technologies miBot Nanomanipulators

The miBot, an ultra compact mobile robot, is capable of manipulating and investigating anything from MEMS, semiconductors, nanoparticles to biological cells. This virtually untethered solution pushes the frontiers of research works to the next level by radically simplifying experiments in microscopes.

The free-to-move miBot provides nanometer-scale resolution of positioning with unmatched freedom of movement along four axes.

Key features of the most-versatile nanomanipulator as follows:

  • Ultra compact design
  • Nanometer-scale resolution of positioning
  • No coupling movements (natural axes)
  • Centimeter traveling range
  • Electro-mechanical tool holder
  • Compatible with different microscopes such as light, SEM, FIB

Optical Microscopy Applications of the miBot

The range of travel of the miBot micromanipulator is several centimetres with a nanometric resolution, making it a suitable replacement for imprecise manual handling used in optical microscopy. It allows lab engineers and researchers to position quickly without manipulating single cells or stressing electrical probes on microelectronics components.

Semi-Automatic Wafer Probing

The probing operation may be sometimes repeated several times on various dies during wafer testing for failure analysis and IC development. This process can be accelerated without moving the probers on the next die’s pads by using a positioning stage for wafer movement with the probers held fixed. The miBase has an option of the 2 degree of freedom positioning stage with a motion range of 13x13 mm.

Fiber Optic Positioning

Optical fibers serve as light conducting components in different types of sensors for the measurement of various physical properties of environments and specimens. Precisely positioning the optical fibers is an essential requirement in several optoelectronics research and development applications to improve photon collection or localized illumination on photovoltaic materials or light emitting or nanostructures. This challenging process can be done easily by utilizing the miBot as a nanometer precision optical fiber positioner.

This figure shows the positioning of an optical fiber using a miBot over an LED, which has an electrical contact with two other miBots. The spectral characteristics of the LED can be measured by this configuration by changing the electrical potential applied on the LED. It is possible to quickly accommodate samples modifications, for instance different shape or smaller/larger size, by taking advantage of the freedom of movement of the miBots or by coarsely repositioning them by hand.

LED Testing

It is easier to perform testing on even the smallest electronic components with the help of two miBot micromanipulators. This application involves the supply of required potential for lighting a micro LED.

An electrical probe is placed on the miBot arm. One of the LED electrical pads is supplied by the first miBot micromanipulator to a ground potential. After the positioning of the first miBot, the second miBot micromanipulator is utilized to supply a 5 V potential to the diode’s second pad.
