Study on the CMP Pad Life with Its Mechanical Properties Pei-Lum Tsoa , Zhe-Hao Huang, Sheng-Wei Chou and Cheng-Yi Shihb Department of Power Mechanical Engineering, National Tsing Hua University, Hsinchu, Taiwan, R.
In this paper, we investigated the physical properties of the CMP pad such as compressibility, thickness, and surface roughness.
From the observed non-uniformity of pad properties, the reason could be due to the non-uniformity in pad conditioning.
Therefore, it is necessary to change the conditioning strategy to improve the uniformity of pad properties.
The pad surface roughness and thickness may influence the material removal rate directly, and the uniformity of both the roughness and thickness are significant factors of CMP with-in wafer uniformity. 2.

The main objective is to evaluate how the addition of recycled glass in different percentages affects the properties of the concrete, in order to identify the optimal mixture that maximizes strength without compromising durability.
Experimental tests are carried out using concrete specimens with different concentrations of recycled glass and their mechanical properties such as compressive and flexural strength will be evaluated.
The workability of concrete with crushed recycled glass can be affected by a variety of factors, including the size and shape of the glass particles, the proportion of water in the mix, and the mixing conditions.
In conclusion, the results of this research demonstrate that the addition of crushed recycled glass to concrete can be a viable and sustainable alternative to improve its mechanical properties.
