    摘要: The present invention is a combination of a laser system and a controller for use in vaporizing the material of a metallized dielectric film capacitor to form a hole in order to trim its capacitance. The combination includes a laser system which has a laser modulator, a mechanical triggering device and a controller which includes a trigger/reset circuit which is electrically coupled to the mechanical triggering circuit and which provides a trigger signal in its triggered state and a reset signal in its untriggered state. The controller also includes a clock circuit which is electrically coupled to the trigger reset circuit and which provides clock signals in response to the trigger signal and a one-shot monostable, multivibrator circuit having an RC timing circuit which is electrically coupled to the clock circuit and to the laser modulator and which controls the pulse width of its output signal in response to the clock signals. The controller further includes a counter which is electrically coupled to the one-shot monostable, multivibrator circuit and which counts each of the clock signals and a comparator which is electrically coupled to the counter in order to compare the number of the counted clock signals to a selected number and which is electrically coupled to the clock circuit. When the number of the counted clock signal equals the selected number, the comparator provides a clock inhibit signal in order to inhibit the clock circuit from providing any more clock signals.

    摘要: The invention discloses a method for detecting a relative positional relation between the coordinate systems of a semiconductor device such as an IC memory and a laser system for cutting a desired wiring pattern. The detecting method according to this invention comprises the steps of scanning a cross-shaped diffusion layer formed on a silicon wafer with a laser beam in a square shape, detecting a change in a current generated when the laser beam crosses the diffusion layer, defining two points at which the current abruptly increases in the X- and Y-axes of the coordinate system of the wafer, respectively, and calculating a reference point (origin) of the coordinate system of the silicon wafer by calculating an intersection of virtual diagonals of a virtual square the four corners of which correspond to the four points in the X- and Y-axes.

    摘要: A laser is used to cut slots into a film deposited on a substrate so that a clean kerf is produced without harming the substrate. The laser cut vaporizes the film material as the removal mechanism and some of the vaporized material will redeposit over the surface of the film adjacent to the kerf. When the redeposited material is illuminated and viewed obliquely a series of light fringes can be observed. The laser focus is adjusted until the fringe pattern is symmetrical about the kerf. The laser power is adjusted until the fringes extend to about three times the kerf width on both sides of the kerf. This provides a precision nonsubjective means for adjusting laser focus and power.

    摘要: A laser processing apparatus includes a support portion, a laser processing head, a vertical movement mechanism, a horizontal movement mechanism, and a controller. The controller controls starting and stopping of emission of a laser light from the laser processing head based on rotation information in a state where a focusing point is positioned at a position along a circumferential edge of an effective region in a target, while rotating the support portion, to perform a circumferential edge process for forming a modified region along the circumferential edge of the effective region in the target.
