It is concluded that, in evaluating the effectiveness of thermal vias in heat loss, simulation can yield results close to observed values by considering the substrate a compound material with a uniform thermal and conductivity coefficient determined by the ratio of thermal via cross section area to substrate area. A thermal via area ratio of 10% is satisfactory both from the standpoint of manufacturing and for effectiveness in decreasing thermal resistance. Also, in the model considered the heat transfer coefficient of the heat sink can be determined by using their speeds and comparison with observed results.<<ETX>>","PeriodicalId":127257,"journal":{"name":"[1991 Proceedings] Eleventh IEEE/CHMT International Electronics Manufacturing Technology Symposium","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134236642","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}

Although HDMI multichip module fabrication equipment and techniques are somewhat related to semiconductor fabrication, there are significant differences which are due to the size of finished parts and to the materials used in the fabrication of MCMs. Past its initial learning curve, minimized costs for second level interconnection are expected from the HDMI technology, because of its optimized geometries compared to other potential second level interconnect technologies. The recently completed pilot facility is to provide data in preparation for the construction of other future large facilities capable of producing parts in large volume, at low cost, for the commercial market. It is pointed out that in order to compete in the world market and to keep a leading edge over competitors, older labor intensive techniques of operating semiconductor plants must be replaced by aggressive automatization.<<ETX>>","PeriodicalId":127257,"journal":{"name":"[1991 Proceedings] Eleventh IEEE/CHMT International Electronics Manufacturing Technology Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129273915","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}

One type of approach being tried in the industry is interconnecting stacked dies by routing their metal lines to the edge of the die and then strapping the appropriate lines from each die together. An approach being pursued by the Center for Microelectronics Research (CMR) at the University of South Florida is the creation of silicon interconnect vias for communication through the active chip or wafer. Vias of 1 to 2 mil diameters have been successfully created by laser ablation of silicon. Studies are currently in progress to determine the effect such via creation has on nearby active devices. A test vehicle containing transistors and capacitors of various geometries is being employed for the purpose of measuring any detriment that the laser drilling has when vias are created. Data are presented on whether any changes have been measured in various parameters, such as subthreshold voltages and current leakage. Scanning electron micrographs are shown, and progress to date on the methodology employed for metallizing the side walls of the vias is discussed.<<ETX>>","PeriodicalId":127257,"journal":{"name":"[1991 Proceedings] Eleventh IEEE/CHMT International Electronics Manufacturing Technology Symposium","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117217099","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}

It was decided to use the IBM multi-layer ceramic (MLC) technology for the carrier substrate because of proven reliability, volume manufacturing capacity, multi-chip capability, wiring flexibility, and performance. Second, it was decided to use a specially designed surface-mount technology (SMT) interconnection to the card instead of the industry standard SMT or pin in hole because of I/O density, cost, and performance. The SMT interconnection was refined through theoretical and empirical investigation along with the low cost, high manufacturability requirement. The result was a high melting point Sn/Pb ball placed in a 0.50\" grid array attached to the substrate and card using eutectic solder. Design concepts to aid in manufacturing are discussed together with the manufacturing/process design, and a typical example of this packaging technology is presented.<<ETX>>","PeriodicalId":127257,"journal":{"name":"[1991 Proceedings] Eleventh IEEE/CHMT International Electronics Manufacturing Technology Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116271565","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 design process presented here uses Monte Carlo analysis along with stochastic approximation to optimize the cost per satisfactory circuit. A relationship is established between the electrical requirements and the manufacturing tolerance of interconnects. Manufacturability signature profiles are presented for various interconnect configurations such as microstrip and buried microstrip.

The algorithm consists of two major processing phases. At the first phase, pre-processing is performed to eliminate noise and to reduce the number of potential candidates of dimple defects. At the second phase, four pattern features are defined based on the consideration of scale-, position-, and orientation-invariant. A fuzzy membership function is utilized to cope with the wide range of shape variations of the dimple defects. A decision-making mechanism is based on the value of the membership function which describes the pattern's closeness to a dimple. The attractive features of the system include the fact that the algorithm is distortion-invariant.
