A plurality of pad openings is formed in the epoxy. Subsequently, a pad circuit re-distribution is arranged over the upper surface of the epoxy. A solder mask covers the epoxy and the pad circuit for isolation. A printing process is carried out to print solder on the pre-determined area and the solder contacts to the pad circuit. Then, the solder is re-flow, and the wafer is then set to a testing apparatus for wafer level testing. A sawing process is next performed after the wafer-level test to separate the dice by cutting the scribe line, thereby obtaining the chip scale package (CSP).

Title: Plasma dry scrubber
Inventor: CHOI DAE-KYU
IPC: B01J19/08
Filed: 2000-11-09
Granted: 2001-10-21
Abstract: A plasma dry scrubber for scrubbing gas is disclosed. The plasma dry scrubber comprises: a plasma generator; an impedance matching unit; and a RF generator. A high frequency signal generated from the RF generator is fed to first and second antennas, which are provided at the upper and lower parts of the plasma generating unit respectively via the impedance matching unit. Gas flowing into the plasma generator is decomposed by means of magnetic fields generated by the first and second antennas, and the decomposed gas is discharged to a vacuum pump via a gas outlet pipe. The magnetic fields generated by first and second antennas are distributed more uniformly in a plasma generating chamber so that plasma discharge is accomplished uniformly. Furthermore, the thickness of the non-conductive isolating plate made of ceramic or quartz for isolating first and second antennas from the plasma generating chamber may be altered if required, whereby any damage of the plasma dry scrubber due to the pressure from a vacuum pump is prevented even if it is used for a long time.

Title: Colour display tube provided with a colour selection electrode
Inventor: HENS THEODOOR CHRISTIAAN ANNA
IPC: H01J29/07
Filed: 2001-03-01
Granted: 2002-09-21
Abstract: In the manufacturing process of a colour display tube (1), the display window (3) is assembled with the funnel shaped part (4) in a furnace by subjecting them to a heat treatment. This heat treatment cam lead to deformation of the colour selection electrode (12), because in colour display tubes (1) with an invar shadow mask (13), the diaphragm parts (15) are made from invar as well, while the corner sections (16) are made from iron in order to obtain enough stiffness. The difference in expansion coefficient between invar and iron leads to shearing of the welds (22) that connect the diaphragm parts (15) to the corner section (16). To overcome this problem the invention proposes to provide the diaphragm parts (15) with slits (23) or impressions (24), which are arranged so that no stress occurs between the spot welds (22) when the colour selection electrode (12) is heated.
