A bare chip mounting method includes: a dicing step for dividing a semiconductor wafer into individual IC chips while the semiconductor wafer is being attached to a carrier; a washing step for washing the diced semiconductor wafer; a bump-bonding for carrying the washed semiconductor wafer to an assembly process while the semiconductor wafer is being attached to the carrier so as to form a bump on an electrode pad of the wafer; and a mounting step for mounting each of the IC chips, on which the bump is formed, onto a circuit formation body.

In a bump bonding technique for forming a bump on an IC, including forming a ball at the tip of a gold wire protruding from a capillary, and providing a metal-to-metal joint by applying ultrasonic vibration from a ultrasonic head through the capillary while pressing the ball against a pad portion on the IC, the metal-to-metal joint is provided by applying the ultrasonic vibration at a frequency in a range of 130 to 320 kHz, more preferably in a range of 170 to 270 kHz, and most preferably at a frequency of 230±10 kHz at room temperatures and atmospheric pressure. Consequently, a bump is formed on an IC having a low heat resistance temperature in a satisfactory joint condition, and a bump is formed with good positional accuracy without giving the influence of heat to the surroundings.

A higher speed moving device moves a capillary at high speed. A low inertial moving and pressing device moves and presses the capillary with low inertia. The high speed motion, and the moving and pressing motion with the low inertia are carried out independently of each other. Thus, an inertia at the low inertial moving and pressing device is reduced, whereby an impact force when a melt ball is driven by the low inertial moving and pressing device into contact with an electrode of a semiconductor integrated circuit is restricted, thus enabling stable formation for minute bumps. On the other hand, operations other than pressing the melt ball to the electrode and joining the melt ball are conducted by driving the capillary by the higher speed moving device, so that productivity is improved.

To provide a film substrate treatment apparatus that appropriately mounts film substrates on an electrostatic adsorption stage. In the film substrate treatment apparatus, adsorption pads are disposed on the first adsorption units that mount film substrates on an electrostatic stage, and a pressing member that presses the edge portion areas of the film substrates against the stage is provided. The film substrates can thereby be reliably attached to the stage, and the film substrates can be appropriately treated in a decompressed atmosphere.

An electronic part mounting apparatus includes a chamber for cleaning a substrate and an electronic part by plasma, amounting mechanism for mounting the electronic part on the electronic part, and a conveying robot for conveying the substrate and the electronic part from the chamber to the mounting mechanism. After plasma cleaned, the substrate and the electronic part are swiftly conveyed to the mounting mechanism by the conveying robot. After the electronic part is mounted on the substrate by the mounting mechanism, the resultant combination of them is pulse heated. Therefore, the electronic part is appropriately mounted on the substrate in a state that those are exposed to the air. A part mounting mechanism is simplified.
