The selective masking effect of a thermally grown layer of silicon
dioxide has been widely utilized as a technique for controlling the
geometry and impurity concentration in semi-conductor device technology.
It is also recognized that the passivation of the silicon surface
by the vitreous silicon dioxide envelope protects the underlying...
A technique was investigated in which a silicon crystal was
used as a very sensitive detector of sub-nanogram quantities of
boron. The unknown quantity of boron was spread uniformly on
the surface of an n-type silicon wafer which was then baked for
diffusion. The measured depth of the p-n junction...
This ethnographic study was conducted among the Meo community of north India to understand cultural norms, prescriptive behaviors, and practices associated with conceptions and contraception among Meo women and men living in five neighboring villages in the region of Mewat. The study goals were to collect ethnographic data on fertility-related...
Background: According to the National Mental Health Survey (NMHS), the treatment gap of any mental disorder in India among the general population was reported to be as high as 83% (R. S. Murthy, 2017). There is insufficient evidence currently describing the treatment gap among the child and adolescent population. Given...
Culture, thought worldview and language have been
discussed for a long time in different fields from various
perspectives. However, the basis of this study is the view
of language as both the product and producer of people just
as people are the producer and product of language. Each
language requires...
Gender relations as well as the social situation of Manchu women have long been ignored in studies of the cultural evolution of the Manchu. By setting the discussion of Manchu women in the context of cultural adaptation, this study reintroduces gender and women's problems into the research on the Manchu...
The Internet of Things (IoT) paradigm brought an ever-increasing dependence on low-power devices to collect sensor data and transmit that information to the cloud, placing greater demand on connectivity and lifespan. In response, rapid worldwide innovation demonstrates the trade-offs in processing, communication, and energy consumption with diverse approaches to low-power...
This thesis presents some experimental results for
producing controlled PN and NPN diffused structures in
silicon by varying the strength of the diffusion sources.
Boron diffusions were carried out in a N₂ atmosphere at
1200°C with 10%, 20%, 30% and 40% B₂0₃ in silicic acid as
sources. Phosphorus diffusions were...
