The grooved surface provides a grating structure that when combined with the pressurized electrical contacts will crush any intervening or attached residue particles, which will then break into smaller particles and fall away from the probe card. Pressure and relative movement of the probe card may be controlled by a variety of measurement sensors.Type: ApplicationFiled: June 6, 2002Publication date: December 11, 2003Inventors: Byoung-Joo Kim, In-Seok Hwang, Ho-Yeol Lee, Soo-Min Byun, Hyung-Koo Kim, Joon-Su Ji

Patent number: 6659847Abstract: A method of cleaning a probe card with probe pins contaminated by testing residue. A cleaning wafer is provided and the uneven surface and the grooves thereon are used to polish surfaces of the probe pins. Two kinds of cleaning operations, which utilize smaller and larger accelerations driving the cleaning wafer, are performed. The cleaning operations utilizing the smaller acceleration are used to polish the surfaces of the probe pins and the cleaning operations utilizing the larger acceleration are used to smooth the uneven surfaces of the probe pins after the former polishing operations. In addition, the cleaning wafer is rotated by various rotation angles to obtain superior cleaning.Type: GrantFiled: August 28, 2002Date of Patent: December 9, 2003Assignee: Powerchip Semiconductor Corp.Inventors: Yu-Hsin Liu, Kuang-Ping Tang
