Ultra-precision engineering: from physics to manufacturing

Ultra-precision engineering: from physics to manufacturing.

Sir Christopher Wren is widely acknowledged as a key individual in the formation of the Royal Society, a society initially advocated ‘for the promotion of physicomathematical experimental learning’. Many people would not be surprised to learn that England’s most famous architect was a driving force behind the Royal Society. But most people would not know that Wren was at that time an astronomer...

Advances in Ultra Precision Manufacturing

In the past many qualified technologies have been established for the manufacture of optical, precision and micro parts as well as precision structured surfaces. In this field mechanical machining processes, like diamond machining, play a dominant role. Novel mechanical manufacturing processes, further development of ultra precision machine tools and the precision machining of challenging mater...

Atomic Step Formation on Sapphire Surface in Ultra-precision Manufacturing

Surfaces with controlled atomic step structures as substrates are highly relevant to desirable performances of materials grown on them, such as light emitting diode (LED) epitaxial layers, nanotubes and nanoribbons. However, very limited attention has been paid to the step formation in manufacturing process. In the present work, investigations have been conducted into this step formation mechan...

Ultra-Precision Metal Additive Manufacturing for Thermal Management of Microelectronics

Thermal management of microelectronic devices is an ongoing technological challenge that directly affects device-level and system-level performance and reliability [1]. The fundamental process of electron transport in a transistor device results in dissipation of heat. This causes temperature rise, which in turn limits device performance. For most semiconductor devices, performance goes down wi...
