  • Patent number: 10822695
    Abstract: A reaction chamber includes a reactor wall, a susceptor contacting the reactor wall to define a reaction space and a gas flow control device and a showerhead member stacked between the reactor wall and the susceptor. The showerhead member includes a gas channel and a showerhead. Penetration holes are formed through a protruding lateral portion of the gas flow control device, and the reactor wall and a lateral portion of the showerhead member are spaced apart from each other to form a gas discharge path. Gas remaining in the gas discharge path is discharged through the penetration holes and a gas outlet formed in an upper portion of the reactor wall. Because of the reaction space and the gas discharge path, unnecessary regions are removed to rapidly change gases from one to another, and thus atomic layer deposition may be performed with high efficiency and productivity.

  • Patent number: 10277255
    Abstract: A channel equalizer includes a first transformer, an estimator, an average calculator, a second transformer, a coefficient calculator, a compensator, and a third transformer. The first transformer converts normal data into frequency domain data, where a known data sequence is periodically repeated in the normal data. The estimator estimates channel impulse responses (CIR) during known data intervals adjacent to each normal data block. The average calculator calculates an average value of the CIRs. The second transformer converts the average value into frequency domain data. The coefficient calculator calculates equalization coefficients using the average value, and the compensator compensates channel distortion of each normal data block using the coefficients. The third transformer converts the compensated data block into time domain data.

  • Patent number: 9879342
    Abstract: A lateral flow atomic layer deposition (ALD) apparatus has two gas inflow channels and two gas outflow channels that are connected to two gas outlets that are symmetrically formed based on a substrate in which a thin film is deposited, thereby differently guiding a flow direction of a gas flowing on the substrate. Therefore, uniformity of a deposited film is improved, compared with the conventional lateral flow ALD apparatus in which a supplied source gas and reaction gas constantly flow in only one direction on the substrate.
