Abstract:
A process for producing a photovoltaic device, wherein when providing an n-type amorphous silicon layer on an i-type amorphous silicon layer, a desired crystallization ratio can be achieved without reducing the deposition rate. The production process comprises a p-layer formation step of depositing a p-type amorphous silicon layer, an i-layer formation step of depositing an i-type amorphous silicon layer on the p-type amorphous silicon layer, and an n-layer formation step of depositing an n-type amorphous silicon layer on the i-type amorphous silicon layer, wherein the n-layer formation step comprises a first n-layer formation step of depositing a first n-layer on the i-type amorphous silicon layer, and a second n-layer formation step of depositing a second n-layer on the first n-layer, and the deposition conditions for the first n-layer formation step are conditions that yield a higher crystallization ratio than the deposition conditions for the second n-layer formation step, for deposition onto the same base material substrate.

Abstract:
A plasma generation device for generating plasma uniformly over a large surface area by very high frequency (VHF), which is installed in a plasma chemical vapor deposition apparatus. A first and a second power supply section are installed on both ends of the discharge electrode installed in a plasma chemical vapor deposition apparatus, and are supplied with alternate cycles: the first cycle wherein the first and second power supply sections receive high frequency waves at the same frequency, and a second cycle wherein different high frequency waves are received. In this manner, the state of plasma generation may be varied in each cycle, and when averaged over time, it makes possible uniform plasma generation over a large surface area.
Abstract:
An electronic device has a display capable of displaying a pointing representation, a detector for detecting a movement of the electronic device, and a display controller for controlling the display so as to move the pointing representation displayed on the display in response to the movement of the electronic device detected by the detector. The pointing representation can be moved by a simplified operation or by moving the electronic device, which consequently reduces the number of operation parts.
Abstract:
A method for making the characteristics of the distribution of film thickness uniform is provided, avoiding generation of phase differences among streams of high-frequency electric power by manipulating the electrical characteristics of cables through which the high-frequency electric power is transmitted. Coaxial cables (19a to 19h and 24a to 24h) having a standard length and vacuum cables (20a to 20h and 25a to 25h) are installed, then a film is formed on a substrate by actually supplying high-frequency electric power, and thereafter the condition of vapor deposition such as the thickness of the film is observed. Based on the observations, the full lengths of the coaxial cables which communicate with the feeding points and the electrodes which correspond with positions over the substrate which need to be adjusted are changed. The coaxial cables are installed again, and high-frequency electric power equivalent to that used in the previous operation is supplied to form a film. The distribution of the film formed on the substrate is made uniform by repeating the above operations.
Abstract:
An object is to provide a high-frequency plasma generating apparatus and process which can further advance uniformity of the thickness of a film on a substrate with a large area in comparison with conventional apparatuses. In a reaction chamber (1), a ground electrode (3) is disposed, and a discharge electrode (2) is disposed opposite to the ground electrode (3). A substrate (4) as a processing object is placed in close contact with the ground electrode (3). A high-frequency voltage is applied to the discharge electrode (2) so as to generate plasma between the ground electrode and the discharge electrode. An RF electric power supply (15) generates a first high-frequency voltage, and outputs the generated voltage on feeding points (9) disposed on a lateral portion of the discharge electrode (2). An RF electric power supply (16) generates a second high-frequency voltage, and outputs the generated voltage on feeding points (9) disposed on another lateral portion of the discharge electrode (2). Here, the second high-frequency voltage has the same frequency as that of the first high-frequency voltage and has a phase which varies with a low-frequency signal, which is modulated by a predetermined modulation signal.
