Inventor: YANG JING-JUN
IPC: H01L21/02
Filed: 1998-03-13
Granted: 2000-10-21
Abstract: A process for the preparation of substrates used in the manufacture of integrated circuits wherein spin-on low dielectric constant (low-k) polymer films are applied on semiconductor substrates. A non-etchback processing of spin-on low-k polymer films, without losing the low dielectric constant feature of the film, especially in between metal lines, is achieved utilizing electron beam radiation. A polymeric dielectric film is applied and dried onto a substrate and exposed to electron beam radiation under conditions sufficient to partially cure the dielectric layer. The exposing forms a relative more hardened topmost portion of the dielectric layer and a relatively less hardened underlying portion of the dielectric layer.

Title: Method for electroplating solder bumps of uniform height on integrated circuit substrate
Inventor: RINNE GLENN A
IPC: H01L21/60
Filed: 1998-04-29
Granted: 1999-07-11
Abstract: A method for electroplating solder bumps of uniform height on the integrated circuit substrate is disclosed, comprising the steps of directing the plating current through an IC wafer by the simultaneous shorting of the IC ground, power and signal pad using an ultra-thin plating base layer (thickness < 0.075 nm), then directing the plating current along the path parallel to said ground and said signal pad into the substrate by using a back side of wafer contact. Said grounding pad preferably electrically connects to the substrate at the contact area (such as N+ or P+ diffusion region), said signal pad preferably electrically connects to said substrate through active semiconductor device (such as FET, BJT, etc.) on which said signal pad is adhered. The plating current is preferably guided parallel through an active semiconductor device and a substrate contact area. The joint contribution of plating current guided through an active semiconductor device and a substrate contact area is sufficient to maintain the potential of said plating base layer and pad underneath it at an uniform level, even if the plating base layer has a preferred thickness of less than 0.075 nm. These uniform and typically non-zero potentials allow the plating speed of the entire wafer to be highly uniform, given that side current is limited from flowing through said plating base layer. The plated tin-soldered bumps also obtain improvement using high-density controlled C4 (flip chip) technique and through the distribution of said ground and signal pad to each flip chip, such that each signal pad has at least one ground pad at its closest proximity.

Title: Detection of bridge tap using frequency domain analysis
Inventor: CHONG RAYMOND L
IPC: G01R31/50
Filed: 2000-04-19
Granted: 2001-10-11
Abstract: A method for detecting the presence of a bridge tap and other types of fault in a transmission line. Initially, test signals of predetermined frequencies are transmitted into a transmitting end of the transmission line. The test signals are received at a receiving end of the transmission line and the amplitudes of the received signal are measured. A frequency response of the transmission line is computed based on the measured amplitudes. The frequency response is then analyzed for the presence of a frequency-domain signature that corresponds to one of the detectable types of fault. The presence of a bridge tap or another type of fault is identified based on the detected frequency-domain signature. The frequency-domain signature associated with a bridge tap can comprise a set of one or more attenuation dips in the frequency response, with each attenuation dip corresponding to a local minima in the frequency response. The length of the bridge tap can be estimated based on a fundamental frequency of the set of harmonically related attenuation dips. Also, the location of the bridge tap in the transmission line can be estimated by performing a time domain reflectometer (TDR) test.
