  • Patent number: 7179397
    Abstract: To move an article in and out of plasma during plasma processing, the article is rotated by a first drive around a first axis, and the first drive is itself rotated by a second drive. As a result, the article enters the plasma at different angles for different positions of the first axis. The plasma cross-section at the level at which the plasma contacts the article is asymmetric so that those points on the article that move at a greater linear velocity (due to being farther from the first axis) move longer distances through the plasma. As a result, the plasma processing time becomes more uniform for different points on the article surface. In some embodiments, two shuttles are provided for loading and unloading the plasma processing system. One of the shuttles stands empty waiting to unload the processed articles from the system, while the other shuttle holds unprocessed articles waiting to load them into the system.

  • Patent number: 7173327
    Abstract: A clock distribution network (110) is formed on a semiconductor interposer (320) which is a semiconductor integrated circuit. An input terminal (120) of the clock distribution network is formed on one side of the interposer, and output terminals (130) of the clock distribution network are formed on the opposite side of the interposer. The interposer has a through hole (360), and the clock distribution network includes a conductive feature going through the through hole. The side of the interposer which has the output terminals (130) is bonded to a second integrated circuit (310) containing circuitry clocked by the clock distribution network. The other side of the interposer is bonded to a third integrated circuit or a wiring substrate (330). The interposer contains a ground structure, or ground structures (390, 510), that shield circuitry from the clock distribution network. Conductive lines (150) in an integrated circuit are formed in trenches (610) in a semiconductor substrate.

  • Publication number: 20050170647
    Abstract: A through hole (114) is formed in a wafer (104) comprising a semiconductor substrate (110). A seed layer (610) is sputtered on the bottom surface of the wafer. The seed is not deposited over the through hole's sidewalls adjacent the top surface of the wafer. A conductor (810) is electroplated into the through hole. In another embodiment, a seed is deposited into an opening in a wafer through a dry film resist mask (1110). The dry film resist overhangs the edges of the opening, so the seed is not deposited over the opening's sidewalls adjacent the top surface of the wafer. In another embodiment, a dielectric (120) is formed in an opening in a semiconductor substrate (110) by a non-conformal physical vapor deposition (PVD) process that deposits the dielectric on the sidewalls but not the bottom of the opening. A seed (610) is formed on the bottom by electroless plating. A conductor (810) is electroplated on the seed.

  • Patent number: 6882030
    Abstract: To fabricate contacts on a wafer backside, openings (124) are formed in the face side of the wafer (104). A dielectric layer (140) and some contact material (150), e.g. metal, are deposited into the openings. Then the backside is etched until the contacts (150C) are exposed and protrude out. The protruding portion of each contact has an outer sidewall (150V). At least a portion of the sidewall is vertical or sloped outwards with respect to the opening when the contact is traced down. The contact is soldered to an another structure (410), e.g. a die or a PCB. The solder (420) reaches and at least partially covers the sidewall portion which is vertical or sloped outwards. The strength of the solder bond is improved as a result. The dielectric layer protrudes around each contact. The protruding portion (140P) of the dielectric becomes gradually thinner around each contact in the downward direction.

  • Patent number: 6740582
    Abstract: To fabricate back side contact pads that are suitable for use in a vertical integrated circuit, vias are made in the face side of a wafer, and dielectric and contact pad metal are deposited into the vias. Then the wafer back side is etched until the metal is exposed. When the etch exposes the insulator at the via bottoms, the insulator is etched slower than the wafer material (e.g. silicon). Therefore, when the dielectric is etched off and the metal is exposed, the dielectric protrudes down from the wafer back side around the exposed metal contact pads, by about 8 &mgr;m in some embodiments. The protruding dielectric portions improve insulation between the wafer and the contact pads when the contact pads are soldered to an underlying circuit. In some embodiments, before the contact pads are soldered, additional dielectric is grown on the wafer back side without covering the contact pads.
