摘要： A method for controlling liquid delivery in a processing chamber. The method includes generating an analog input (AI) signal proportional to a process variable and calculating an analog output (AO) signal based on a setpoint and a deadband. The setpoint is a target value of the process variable and the deadband is an allowable tolerance around the setpoint that determines when the control logic is activated to control the process variable. The method further includes transmitting the AO signal to a control device and adjusting the process variable proportional to the value of the AO signal.

An exemplary method for filtering an optical signal may include providing a composite optical signal having several wavelengths including a first wavelength, a second wavelength and other wavelengths. The method may include passing the first wavelength through a filter and reflecting the second wavelength and the other wavelengths with the filter. The method may include making the first wavelength available to a drop port, and making the second wavelength and the other wavelengths available to an output port.

摘要： A first signal is received from an initial quantum key generating transmitter via a single combined channel that includes a first quantum signal and a public data signal alternating in a time shared manner. The first signal is split into first and second split signals. A low attenuation is applied to the first split signal when the first split signal includes the first quantum signal. A high attenuation is applied to the first split signal when the second split signal includes the public data signal. The first split signal is received at an intermediate quantum key generating receiver (QKGR) when the low attenuation is applied and a first quantum key is generated. A second quantum signal is transmitted to a recipient QKGR and a second quantum key is generated. The first quantum key is encoded using the second quantum key and transmitted to the recipient QKGR.

摘要： One embodiment provides an apparatus for material deposition. The apparatus includes a reaction chamber, and a pair of susceptors. Each susceptor has a front side mounting substrates and a back side. The front sides of the vertically positioned susceptors face each other, and the vertical edges of the susceptors are in contact with each other. The apparatus also includes a number of gas nozzles for injecting reaction gases. The gas flow directions inside the chamber can be alternated by controlling the gas nozzles. The gas nozzles are configured to inject a small amount of purge gas including at least one of: HCl, SiCl4, and H2 when the gas nozzles are not injecting reaction gas. The apparatus includes a number of heating units situated outside the reaction chamber. The heating units are arranged in such a way that they radiate heat energy directly to the back sides of the susceptors.
