									- WLCSP MMICs for Micro/Millimeter-wave Applications
														SEI/SEDI proposes the 
														WLCSP (Wafer
														Level
														Chip
														Scale
														Package) 
														technology for the 
														solution of the next 
														generation device.
															
																
															
																
														
														
															
														
															
																
															
														
															
													
													This technology achieved a very excellent frequency performance by uniting with 3- D MMIC technology, and can apply from C to E-band applications.
The WLCSP chip is the flip chip form with the solder ball and it is mountable in the SMT production line.
It is unnecessary the wire bonding, it can achieve high mass productivity up to high frequency range.
