IPC: H01L21/60
Filed: 1992-02-24
Abstract: PURPOSE:To realize a series of operations at high speed from the stamping operation of a device from a film carrier up to the bonding operation of the device onto a substrate by a constitution wherein the device obtained by stamping the film carrier is delivered from a first transfer head directly to a second transfer head by means of a baton-pass system. CONSTITUTION:A device P which is obtained by stamping a film carrier 2 by means of a stamping apparatus is sucked and picked up by means of nozzles 10a, 10b at a first transfer head 28. Then, while the device P is transferred up to a delivery position (a), the nozzles 10a, 10b are turned over upside down by using an up-and-down inversion means. Then, the device P which has been sucked by means of the upward faced nozzles in the delivery position (a) is received by a second transfer head 13 and mounted on a substrate which has been positioned in a positioning part. When the device P is delivered directly to the second transfer head 13 from the first, transfer head 28, a Takt from the stamping operation of the film carrier 2 up to the mounting operation of the device on the substrate is shortened, and a bonding operation can be performed with good operating property and with good accuracy.

Abstract: PURPOSE:To produce semiconductor elements from breakdown by a method wherein an impurity region of one conductivity type, an impurity region of the opposite conductivity type, an insulating film for a gate, and a gate electrode are provided. CONSTITUTION:In the event an excess voltage is inputted from an external terminal, or in the vent the potential of an impurity region 3 in floating conditions rises for the potential difference between a gate electrode 8 and the impurity region 3 to exceed the threshold voltage of a MOSFET 11, the MOSFET 11 is turned on. Accordingly, the electric charge resulting from the excess voltage applied to an input terminal is discharged to impurity regions 4 and 1, for the excess voltage to be effectively absorbed. An insulating film 6 formed thick enables the threshold voltage of the MOSFET 11 to be set with ease at a value higher than the power source voltages at which inner circuit elements function. With the device being designed as such, internal semiconductor elements are protected from breakdown due to excess voltage such as statics, etc.
