We have developed novel low-transmission-loss multilayer materials suitable for PWBs applied to high GHz bands. The laminates made with new resins have good dielectric properties and show the same level of low dissipation factor as the PTFE laminate. Moreover, they have high Tg, low moisture absorption, and good heat resistance suited for the lead-free soldering process.","PeriodicalId":412754,"journal":{"name":"Polytronic 2007 - 6th International Conference on Polymers and Adhesives in Microelectronics and Photonics","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128983905","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}

For the SAB with nano-adhesion layer, although in tensile tests fractures occur at the bonded interfaces, the bonding strength is sufficient to withstand diced by 500times500 mum2 small pieces, and no annealing voids raised by post-annealing from 200 to 600degC. For SPAB, short O2 reactive ion etching (RIE) plasma pretreatment time for 10 s and followed by N2 radicals for 60 s can mitigate void formation very much during post-annealing between 200~700degC, moreover, under this pretreatment process, wafer bonding strength equivalent to bulk-silicon is achieved at room temperature without requiring annealing.","PeriodicalId":412754,"journal":{"name":"Polytronic 2007 - 6th International Conference on Polymers and Adhesives in Microelectronics and Photonics","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132557671","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}

However, the size reduction was traditionally confined to lateral dimensions, until recently in the 21st century, the real estate in the Z-direction has been severely compromised, therefore, THIN has become the buzz word encompassing thin die, thin dielectric, thin passives, thin core and ultimately leading to thin packages. This paper overviews the trends from thick to thin electronic products, materials, processes, and manufacturing of the thick and thin packages with embedded passive components such as resistors, capacitors, inductors, and lately the Actives. Flexible organics with embedded IC and thin film passive materials and substrates that can perform at frequencies in the range 2-110 GHz has been established with liquid crystal polymers . A roadmap for the realization of highly integrated RPID tags with wireless sensors and thin film batteries on ULTIMATE low-cost synthetic material such as photocopy papers has been addressed. To this regard, special attention is given to miniaturization of antennas and on specific techniques for ultra-high-efficiency (95%) RFID's. Examples of paper-based conductive Ink-Jet printed circuits as well as copper circuitary by etching have been investigated as a means for further cost reduction including ultra-thin printed batteries and power-scavenging devices, as well as to miniaturized sensors (temperature, chemical, pressure) that would enable long-range ubiquitous sensing.

This study describes a process for copper micro patterning in parylene-C thin film that combines the hot-embossing and electroplating techniques. The process begins with the deposition of a parylene film on a silicon wafer by a vapor deposition polymerization method. To improve the adhesion of a parylene-C onto a silicon, a silicon wafer was treated using SF6 plasma for 2 min, and spin-coated with an adhesion promoter before parylene deposition. Then, the surfaces of parylene-C films were embossed and subsequently treated by O2 plasma at 2 min to improve the adhesion between the parylene and the Cu/Ta seed layer. Finally, micro-scale gap-filled copper lines with the aspect ratio of 2.5 were electroplated, and the back side of electroplated metal is planarized to the level of the top of the parylene-C layer by a chemical mechanical planarization (CMP) process.","PeriodicalId":412754,"journal":{"name":"Polytronic 2007 - 6th International Conference on Polymers and Adhesives in Microelectronics and Photonics","volume":"217 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116489102","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}

This method utilizes capillary force generated by two different liquid of TEGDMA (triethyleneglycol dimethacrylate) and 42Sn-58Bi solder as adhesives. TEGDMA with an additional thermal initiator is liquid at room temperature and hardens by heat. 42Sn-58Bi solder is solid at room temperature and melts at 138 degC. Since TEGDMA and 42Sn-58Bi solder are selectively utilized as adhesives by setting the process temperature at room temperature for TEGDMA and 150 degC for 42Sn-58Bi solder, the sequential self-assembly of different components can be realized. The feasibility of the proposed process and alignment accuracy are experimentally and theoretically examined using 1 mm square silicon chips as test components. The first component assembly on a substrate is carried out at room temperature using TEGDMA, and the second component assembly on the assembled component is carried out at 150 degC using 42Sn-58Bi solder. Both assembly steps are carried out in EG (Ethylene Glycol) solvent with an additional sulfuric acid. It was confirmed that the first and the second assembly were successfully done at room temperature and at 150 degC, and alignment accuracy of the first and the second assembly were 33 mum and a few mum, respectively.","PeriodicalId":412754,"journal":{"name":"Polytronic 2007 - 6th International Conference on Polymers and Adhesives in Microelectronics and Photonics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125943241","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}
