Title: Electrostatic chuck device
Inventor: MAIKERU SUKOTSUTO BAANZU
IPC: H01L21/683
Filed: 1994-09-27
Abstract: PURPOSE: To suppress the formation of vacuum arcs between the back of a wafer in the middle of a process and an electrostatic chuck main body by laying a conductive protection circle floating near self-bias potential, introduced by plasma on the wafer. CONSTITUTION: A circular path 515 extends to the periphery of the outer part of a top face in an electrode 200 and forms a gas supply groove. A protective film 300 facing downward has a thin conductive member 265 having the top face which is flush with the top face 210 of a grasping electrode. A base part 260 is insulated form the electrode 200, and it floats by coupling capacity to a potential approximated to the wafer potential. A wafer 600 is brought into contact with plasma, and therefore it is in self-bias potential which is much lower than the time-averaged plasma potential. Namely, the time-averaged potential on the wafer is typically much smaller than ground potential. Thus, the protective film establishes an equipotential region, which is equal to the potential of a work piece between the work piece and an outer electrode.

Title: Power supply device, discharge lamp lighting device and lighting system
Inventor: NAKAYA FUMINORI
IPC: H05B41/24
Filed: 1992-08-31
Abstract: PURPOSE:To provide a discharge lamp lighting device having the capability of preventing a pre-regulator from malfunctioning. CONSTITUTION:The voltage of a commercial AC power supply E is full-wave rectified via a full-wave rectifier 21. A power factor is improved and voltage is raised with a booster chopper circuit 22. Also, voltage is lowered with a step-down chopper circuit 23. Furthermore, voltage is converted to high-frequency AC current, thereby lighting a discharge lamp FL. Before the discharge lamp FL lights, voltage across the resistors R1 and R2 of a startup circuit 24 increases to actuate a trigger element Q3. A thyristor Th1 is thereby turned on, and caused to resonate with a capacitor C4 and an inductor L3. Furthermore, an inductor L4 is caused to generate pulses, and the discharge lamp F1 is thereby made to start operation. After the operation start of the discharge lamp FL, voltage across the resistors R1 and R2 drops, and no pulse is supplied from the startup circuit 24. While this circuit 24 is operating, output from the booster chopper circuit 22 is kept approximately at a value between 10% and 15%, compared with the case of normal operation.

Title: Laser light control circuit for optical disk recording and reproducing device
Inventor: IZUMI YASUHIKO
IPC: G11B7/125
Filed: 1986-09-30
Abstract: PURPOSE:To stabilize the output of a laser diode by sampling an optical output control signal at the time when the modulated signal inputted to a laser current driving part is in the reproducing level. CONSTITUTION:At the time of recording operation in an optical disk recording and reproducing device, the modulated signal is inputted from a modulating part 4 to a laser current driving part 5. Then, an S/H circuit 5a samples a signal for the reproducing level (H level) out of the optical output control signal outputted from an APC part 2 and holds it at the fall timing of a pulse signal. It is held during the recording level (L level). Thus, the automatic output control of the laser light outputted from a laser diode LD is performed with the optical output control signal for the same stable reproducing level as the reproducing operation at the time of recording operation in the optical disk recording and reproducing device.

IPC: G01N27/26
Filed: 1989-09-11
Abstract: PURPOSE:To obtain a highly accurate variation speed corresponding to the brittleness of a metallic material by measuring variation in natural potential with time which is caused by bringing an electrolyte into contact with the metallic material without destruction and further calculating the variation speed at the time when the 2nd-stage differentiation coefficient of the natural potential becomes minimum. CONSTITUTION:While the electrolyte 2 is put in and brought into contact with the surface of a body 5 to be inspected (metallic material), the electrolyte 2 is stirred by a stirrer 9 to flow and the time variation in the natural potential of the metallic material after the stirring operation is stopped is measured. The measured natural potential is differentiated by a variation speed calculator 11, the variation speed of the natural potential at the time when the 2nd-stage differentiation coefficient becomes minimum is selected as an evaluated value, and brittleness corresponding to the variation speed of the natural potential which is selected as the evaluated value is calculated from the relational expression between brittleness which is already known and the natural potential. Consequently, a detection error is small and detecting operation is easily and speedily performed.

Abstract: PURPOSE:To equalize the growth rate of a plating and to form a bump of an even film thickness by a method wherein a plating object region is divided into at least two regions of the central part of a semiconductor wafer and the outer peripheral part of the wafer through a scribing line and the plating is controlled on every region. CONSTITUTION:A barrier metallic film 22 on a semiconductor wafer 2 is removed along a scribing line 22c to pass on the peripheral edge end of a range reduced 1/2r from its radius (r) and plating object regions A and B, each consisting of each of barrier metallic films 22a and 22b, are formed.
