23-822: MOSIS (Metal Oxide Semiconductor Implementation Service) is multi-project wafer service that provides metal–oxide–semiconductor (MOS) chip design tools and related services that enable universities, government agencies, research institutes and businesses to prototype chips efficiently and cost-effectively. Operated by the University of Southern California's Information Sciences Institute (ISI) , MOSIS combines customers' orders onto shared multi-project wafers that speed production and reduce costs compared with underutilized single-project wafers. Customers are able to debug and adjust designs, or to commission small-volume runs, without making major production investments. Fabrication costs are also shared by combining multiple designs from

46-426: A chip integration. Selecting the right service platform at the prototyping phase ensures gradual scaling up production via MPW services taking into account the rules of the selected service. MPC/MPW arrangements have also been applied to microelectromechanical systems (MEMS), integrated photonics like silicon photonics fabrication, flexible electronics, microfluidics and even chiplets . A refinement of MPW

69-481: A lower cost. Annually, more than 700 research teams from companies and 100 academic institutions around the world access CMC's services and turn more than 400 designs into prototypes through its global network of manufacturers. This support enables 400 industrial collaborations and 1,000 trained HQP to join industry each year, and these relationships assist in the translation of academic research into outcomes—publications, patents, and commercialization. Muse Semiconductor

92-434: A single package to create a complex component such as a computer processor. Each chiplet in a computer processor provides only a portion of the processor's total functionality. A set of chiplets can be implemented in a mix-and-match " Lego -like" assembly. This provides several advantages over a traditional system on chip ( SoC ) which is monolithic as it comprises a single silicon die: Multiple chiplets working together in

115-454: A single customer onto one " mask set," or wafer template. According to MOSIS, the service has delivered more than 60,000 integrated circuit designs. Funded by DARPA, MOSIS was created in 1981 by ISI's Danny Cohen , an Internet pioneer who also developed Voice over Internet Protocol and Video over Internet Protocol. It was based on the revolutionary VLSI design methodology of Carver Mead and Lynn Conway , who pioneered and/or popularized

138-407: A single integrated circuit may be called a multi-chip module , hybrid IC , 2.5D IC , or an advanced package . Chiplets may be connected with standards such as UCIe , bunch of wires (BoW), AIB, OpenHBI, and OIF XSR. Chiplets not designed by the same company must be designed with interoperability in mind. The term was coined by University of California, Berkeley professor John Wawrzynek as

161-522: Is a combination of several designs and this combined chip is then repeated all over the wafer during the manufacturing. MPC arrangement produces typically roughly equal number of chip designs per wafer. With the MPW arrangement, different chip designs are aggregated on a wafer, with perhaps a different number of designs/projects per wafer. This is made possible with novel mask making and exposure systems in photolithography during IC manufacturing. MPW builds upon

184-524: Is a not-for-profit organization in Canada accelerating research and innovation in advanced technologies. Founded in 1984, CMC lowers barriers to designing, manufacturing, and testing prototypes in microelectronics, photonics, quantum, MEMS, and packaging. CMC technology platforms such as the ESP (Electronic Sensor Platform) jumpstart R&D projects, enabling engineers and scientists to achieve results sooner and at

207-421: Is multi-layer mask (MLM) arrangement, where a limited number of masks (e.g. 4) are changed during manufacturing at exposure phase. The rest of the masks are the same from the chip to chip on the whole wafer. MLM approach is well suited for several specific cases: Typically MLM approach is used for one wafer batch (consisting of several wafers depending on the fabrication line) and for one customer. By using MLM it

230-404: Is possible to get larger devices (even up to wafer size) or larger number of dies and wafers up to few batches typically. MLM is a smooth continuation from MPW production volumes upwards and therefore this may support also small/mid size volume production. Not all foundries support MLM arrangements. Due to the complexity of the technologies available and the need to run MPC/MPWs smoothly, following

253-418: Is targeted globally additionally to universities also for research institutes, small possibly start up phase companies and specifically as a first step to convert and test transition from FPGA to an integrated circuit. Chiplet A chiplet is a tiny integrated circuit ( IC ) that contains a well-defined subset of functionality. It is designed to be combined with other chiplets on an interposer in

276-702: The cases the quality of the manufacturing process is guaranteed by the measurement results of process control monitor(s) (PCM) or similar. MPC approach was one of the first hardware service platforms in semiconductor industry, and the more flexible MPW arrangement is continuing to be part of well established microelectronics manufacturing and foundry model not limited to silicon IC manufacturing but spreading into other semiconductor production areas for cost effective prototyping, development and research. Many MPC/MPW arrangements were first nationwide activities, but were expanded international, global co-operative activities based on emerging foundry technologies: CMC Microsystems

299-641: The fabrication process at foundries. The completed chips (packaged or bare dies) are returned to customers. The first international silicon IC MPC service NORCHIP was established among four nordic countries ( Denmark , Finland , Norway and Sweden ) 1981 delivering first chips 1982. It was funded by Nordic Industrial Fund and R&D financing organisations from each participating country. Targets were training and to enhance cooperation between research and industry specifically in areas of analog and digital signal processing and power management Integration. Parallel with NORCHIP organised by same nordic countries there

322-659: The older MPC procedures and enables more effective support for different phases and needs of manufacturing volumes of different designs/projects. MPW arrangement support education, research of new circuit architectures and structures, prototyping and even small volume production. Worldwide, several MPW services are available from companies, semiconductor foundries and from government-supported institutions. Originally both MPC and MPW arrangements were introduced for integrated circuit (IC) education and research; some MPC/MPW services/gateways are aimed for non-commercial use only. Currently MPC/MPW services are effectively used for system on

345-538: The rules, timing of the designs and use of suggested design tools are critical for leveraging the benefits of MPC/MPW services. However every service provider has its own practicalities including design data, die sizes, design rules, device models, design tools used, ready IP blocks available and timing etc. Turn around times and cost of MPC and MPW services depend on the manufacturing technology and designs/prototypes are typically available as bare dies or as packaged devices. Deliveries are typically untested, but in most of
