Overview
This paper introduces a 3D additive micromanufacturing strategy (termed ‘micro-masonry’) for the flexible fabrication of microelectromechanical system (MEMS) structures and devices. This approach involves transfer printing-based assembly of micro/nanoscale materials in conjunction with rapid thermal annealing-enabled material bonding techniques.

What is micro-masonry?
Micro-masonry is a 3D additive micromanufacturing strategy for creating MEMS structures using transfer printing techniques.
How are micro objects prepared for transfer printing?
Micro objects are prepared on donor substrates and suspended on patterned photo resist supporters.
What role does the elastomeric microtip stamp play?
The stamp aligns with the ink, applies preload to form adhesive contact, and retrieves the ink for transfer.
What are the main advantages of this method?
This method allows for flexible fabrication and precise assembly of micro/nanoscale devices.
What materials are used in this study?
Silicon and gold are used as inks for the micro objects in the transfer printing process.
