The InAlAs/InGaAs metamorphic HEMT (mHEMT) two-stage Ka-band amplifier and DC-30 GHz distributed SPST switch were designed and fabricated using low-k benzocyclobutene (BCB) bridged technology. This fabrication technology takes the advantages of its low dielectric permittivity (2.7), low loss tangent (0.008), low curing temperature, low water up-take, and simple manufacturing process. The MMIC f...

Our recently developed approach of UHV-tip-enhanced Raman spectroscopy permits us to acquire Raman spectra of a few single brilliant cresyl blue (BCB) molecules and even a single one adsorbed on a Au(111) surface. This is substantiated by simultaneously recorded STM images. Furthermore, because of the reduced photobleaching in UHV, the time frame for spectral acquisition is sufficiently extende...

This chapter provides an overview of a hybrid metal/polymer wafer bonding plat-form using damascene-patterned intermediate layers for wafer bonding and elec-trical interconnections. This hybrid bonding platform combines the advantagesof metal-to-metal bonding (for direct electrical interstrata interconnection) andpolymer bonding (for robust thermomechanical wafer bonding strengt...

Article history: Received 24 May 2015 Received in revised form 22 June 2015 Accepted 2 July 2015 Available online xxxx Mechanical residual stress after technological process has been investigated on 1200 V Deep Trench Termination Diode. The dielectric used to fill the trenches was the BenzoCycloButene (BCB). Four years after the fabrication and storage in a clean roomwithout any electrical or t...

Baker Cleanser Bitters (BCB) - a polyherbal formula commonly used in the treatment of diabetes, liver cirrhosis, kidney failure, rheumatism and arthritis was evaluated in an acute and sub-chronic toxicity study in Wistar albino rats. A single administration of BCB was given orally at the highest dose level of 2000 mg/kg body weight in the acute toxicity study. Signs of toxicity were observed ev...

There is growing interest in the use of mechanical energy to alter the molecular and supramolecular structure of polymers to create stress-responsive materials.1a-l Chemical reactions that are accelerated by force remain poorly understood, and there is a need for the rapid discovery of new mechanophores (i.e., stress-sensitive units). Screening putative mechanophores, however, is a slow process...

objective: nutrients and antioxidants in the medium of immature oocyte have a profound effect on maturation, fertilization and development of resulting embryos. in this study the effects of melatonin as an antioxidant agent on maturation, glutathione level and expression of high mobility group box-1 (hmgb1) gene were evaluated in immature oocytes of mice stained with brilliant cresyl blue (bcb)...
