Abstract: The present invention is a semiconductor device having and a method for forming wells by growing an epitaxial silicon layer wherein the epitaxial silicon layer has at least three silicon sublayers. The first sublayer is highly doped, the second sublayer is less doped, and the third sublayer is also highly doped. The use of the epitaxially grown wells allows for the placement of high dopant concentrations in regions of the well where electrical isolation is an issue and the placement of lower doped concentrations in regions of the well where electrical isolation is not as great an issue in order to help reduce the problem of parasitic capacitance.

Abstract: A monitoring device to monitor process induced charge employing a single layer of polysilicon forming a floating gate. The device comprises two capacitors, one for charging and the other for discharging a floating gate of an n-channel transistor. Embodiments which permit the monitoring of positive charge, negative charge and both positive and negative charge are described. The device is reusable and lends itself to in-line monitoring as opposed to some prior art devices used for end-of-line monitoring.

Abstract: Surface modification control stations and methods in a globally distributed array for dynamically adjusting the atmospheric, terrestrial and oceanic properties. The control stations modify the humidity, currents, wind flows and heat removal rate of the surface and facilitate cooling and control of large area of global surface temperatures. This global system is made of arrays of multiple sub-systems that monitor climate and act locally on weather with dynamically generated local forcing & perturbations for guiding in a controlled manner aim at long-term modifications. The machineries are part of a large-scale system consisting of an array of many such machines put across the globe at locations called the control stations. These are then used in a coordinated manner to modify large area weather and the global climate as desired. The energy system installed at a control stations, with multiple machines to change the local parameters of the ocean, these stations are powered using renewable energy (RE) sources including Solar, Ocean Currents, Wind, Waves and Batteries to store energy and provide sufficient power and energy as required and available at all hours. This energy is then used to do directed work using special machines, that can be pumps for seawater to move ocean water either amplifying or changing the currents in various locations and at different depths, in addition it will have machineries for changing the vertical depth profile of the ocean of temperature, salinity and currents. Control stations will also directly use devices such as heat pumps to change the temperatures of local water either at surface or at controlled depths, or modify the humidity and salinity to change the atmospheric and oceanic properties as desired. The system will work in a globally coordinated manner applying artificial intelligence and machine learning algorithms to learn from observations to improve the control characteristics and aim to slow down the rise of global surface temperatures. These systems are used to reduce the temperatures of coral reefs, arctic glaciers and south pacific to control the El Nino oscillations.
