Different process applications may need different requirements for the application performance of materials. For example, the temporary bonding adhesive may be bonded with different surface of device wafer like gold layer, silicon and glass, which may also show different adhesive property. What needs to be emphasized is that the bonding wafers are easily peeling off with lower bonding strength, which may lead to low yield. And the bonding wafers with higher bonding strength may difficult to be released and cleaned. Therefore, the bonding strength of temporary bonding adhesive applied to different substrates should be considered as a crucial factor for application. There are several methods to release the wafers when de-bonding such as thermal sliding, mechanical peeling, solvent release and laser irradiation. In this paper, UV laser release systems with release layer and adhesive layer was focused. We studied several adhesive materials (both Adhesive B and Adhesive C were modified by Adhesive A) which showed different shearing strength with different substrates such as gold, silicon and glass. The shearing strength was studied by thrust force shearing force tester (DAGE 4000, USA). The chip with the size of 1mm ×1 mm was bonded on the substrates by the same pressure. The study showed that Adhesive C has higher shearing strength on different substrate. In addition, thermal stability was investigated by thermal gravimetric analyzer (TGA/DSC 2, Germany).","PeriodicalId":186840,"journal":{"name":"2018 IEEE International Conference on Integrated Circuits, Technologies and Applications (ICTA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128405172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key element of DNN is to explore the real time hardware implementation. However, it requires a complete knowledge of hardware where the DNN is going to be implemented. The computational complexity and resource consumption of DNN is increasing by the time. Convolutional Neural Network (CNN) is the popular architecture of DNN especially for image classification. One requires an efficient implementation strategy of CNN to incorporate more computations in real time. Field Programmable Gate Array (FPGA) is considered to be the energy efficient choice for CNN as compared to Graphical Processing Units (GPUs). In this paper, new idea is explored and implemented for basic Processing Element (PE) of CNN. FPGA has limited built-in multiplier accumulator (MAC) units. In this work, MAC units are replaced by Wallace Tree based Multiplier which belongs to the family of log time array multipliers.
