Thermal Modeling of Heat Transfer within Copper Heated Roller of Laminated Object Manufacturing Apparatus: Accumulated Heat, 2D Axisymmetric Transient and Stationary Heat Conduction Models

Laminated Object Manufacturing (LOM) is an efficient rapid prototyping technology (RPT), a suitable technique with many applications. However, its application for wood product prototyping (WPP), especially in micro-thin wood objects, namely different types of wood veneers, the thermal heat effect emanating from LOM heat sources, challenge the quality of the final 3D wood products.

Monolithic Fabrication of Film Bulk Acoustic Resonators above Integrated Circuit by Adhesive- Bonding-Based Film Transfer

An integration process for the fabrication of thin film bulk acoustic wave resonator (FBAR) above the CMOS IC is proposed. An adhesive-bonding-based film transfer technique is utilized to transfer high resistivity Si film onto a CMOS chip. Benzocyclobutene (BCB) is used as an adhesive film. It is a heat resistive polymer and processes of temperature up to 300 C are allowed on it. The CMOS is protected by BCB and thus is not damaged by plasma and chemical treatments.
