The development of high-power EUV sources is a long-term critical challenge to the implementation of EUVL in high-volume manufacturing (HVM), together with other technologies such as photoresist and mask. Historically, both theoretical studies and experiments have clearly indicated that the CO₂ laser-produced plasma (LPP) system is a promising solution for EUVL source, able to realize high conversion efficiency (CE) and output power. Currently, ASML's NXE:3400B EUV scanner configuring CO₂ LPP source system has been installed and operated at chipmaker customers. Meanwhile, other research teams have made different progresses in the development of LPP EUV sources. However, in their technologies, some critical areas need to be further improved to meet the requirements of 5 nm node and below. Critically needed improvements include higher laser power, stable droplet generation system and longer collector lifetime. In this paper, we describe the performance characteristics of the laser system, droplet generator and mirror collector for different EUV sources, and also the new development results.</p></div>","PeriodicalId":100244,"journal":{"name":"Chip","volume":"1 3","pages":"Article 100019"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S270947232200017X/pdfft?md5=b843d53a882992bbff208925b17f073e&pid=1-s2.0-S270947232200017X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85788521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the most envisioned quantum technologies such as quantum communications, quantum computer and quantum simulations have placed a strict constraint on the scalability of chip-integrated quantum light sources. By introducing size-confined nanostructures or crystal imperfections, low-dimensional semiconductors have been broadly explored as chip-scale deterministic single-photon sources (SPSs). Thus far a variety of chip-integrated deterministic SPSs have been investigated across both monolithic and hybrid photonic platforms, including molecules, quantum dots, color centers and two-dimensional materials. With the rapid development of the chip-scale generation of single photons with deterministic quantum emitters, the field of IPQCs has raised new challenges and opportunities. In this paper, we highlight recent progress in the development of waveguide-coupled deterministic SPSs towards scalable IPQCs, and review the post-growth tuning techniques that are specifically developed to engineer the optical properties of these WG-coupled SPSs. Future prospects on stringent requirement for the quantum engineering toolbox in the burgeoning field of integrated photonics are also discussed.</p></div>","PeriodicalId":100244,"journal":{"name":"Chip","volume":"1 3","pages":"Article 100018"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2709472322000168/pdfft?md5=1c902eeb90c42d7cf5a845897160aa7d&pid=1-s2.0-S2709472322000168-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83931467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, thermal conductivity and damping properties are usually correlated and coupled each other. Here, inspired by Maxwell theory and adhesion mechanism of gecko's setae, we present a strategy to fabricate polydimethylsiloxane-based composite gels integrating high thermal conductivity and remarkable damping properties over a broad frequency and temperature range. The multiple relaxation modes of dangling chains and the dynamic interaction between the dangling chains and aluminum fillers can efficiently dissipate the vibration energy, endowing the composite gels with ultrahigh damping property (tan δ &gt; 0.3) over a broad frequency (0.01 – 100 Hz) and temperature range (–50 – 150 °C), which exceeds typical state-of-the-art damping materials. The dangling chains also comfort to the interfaces between polymer matrix and aluminum <em>via</em> van der Waals interaction, resulting in high thermal conductivity (4.72 ± 0.04 W m^–1 K^–1). Using the polydimethylsiloxane-based composite gel as TIMs, we demonstrate effective heat dissipation in chip operating under vigorous vibrations. We believe that our strategy could be applied to a wide range of composite gels and lead to the development of high-performance composite gels as TIMs for chip heat dissipation.</p></div>","PeriodicalId":100244,"journal":{"name":"Chip","volume":"1 2","pages":"Article 100013"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2709472322000119/pdfft?md5=c55536d72023afcc72dda11db3dcff23&pid=1-s2.0-S2709472322000119-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76898508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Boson sampling, a problem about quantum evolutions of multi-photons on multimode photonic networks, as well as its variants, has been considered as a promising candidate to reach this milestone. However, the current photonic platforms suffer from the scaling problems, both in photon numbers and circuit modes.
