Drying thermo-sensitive materials involves a unique process where heat is applied to materials inside a vacuum chamber. This method is advantageous because it allows for drying at lower temperatures, reducing the risk of thermal degradation of sensitive materials. The absence of atmospheric pressure in the vacuum also speeds up the drying process and prevents oxidation, making it an efficient and controlled way to remove moisture. This technique is widely used in various industries, including pharmaceuticals, biotechnology, and manufacturing, where preserving the integrity of materials during the drying process is crucial.

Nanofabricated devices are generally made in batches on wafers and need to be separated or packaged before use. This separation can be achieved through wet or dry dicing. In a wet dicing operation, a precision, high-speed, diamond impregnated blade is used to mill narrow grooves between the devices either partially or completely through the wafer. During this process, water is circulated over the cutting surface to cool the blade and prevent the liberation of dangerous particulates into the air. Materials which would be damaged by water are diced using a dry process known as scribing. Scribing utilises a diamond tipped stylus which is drawn across the wafer surface creating lines of high-stress which are later broken over precision fulcrum.

Wire bonding is the part of the fabrication that allows an electrical component to communicate with the outside world. A thin electrically conductive wire – typically gold, aluminium, copper or silver – is used to allow electricity to flow from contacts on the component to, or from, its packaging. There are two commonly used types of wire bonding – wedge and ball. Which one is more suitable depends on the substrate, the contact material, the bonding material, and a number of other physical factors. Bonders can be manual or automated, and some can feature pattern recognition software to help speed the bonding process up.

Fiber Optic Assembly & Adhesion refers to the precise alignment, bonding, and integration of optical fiber components within various systems. This technique ensures optimal signal transmission, mechanical stability, and long-term reliability in optical communication and sensing applications. It involves advanced positioning, adhesive curing, and automated processes to achieve micrometer-level accuracy in fiber connections. Commonly used in telecommunications, photonics packaging, and high-precision optical systems, this method enhances performance by minimising insertion loss and maintaining structural integrity.

Bonding a wafer to another wafer is a step commonly used when packaging components in an micro or nanoelectrical device. It can help a form new functions in a device, or can ensure mechanical and hermetic encapsulation of devices and electronics. The result is irreversible. Common bonding methods include using heat or with an adhesive for thermally sensitive samples.
