Title: Surface acoustic wave devices
Inventor: ESTE GRANTLEY OLIVER
IPC: H01L41/08
Filed: 1986-04-22
Granted: 1990-09-04
Abstract: SURFACE ACOUSTIC WAVE DEVICES Abstract of the Disclosure An interdigitated transducer (IDT) has parallel electrodes extending inwardly from one voltage rail and parallel electrodes extending inwardly from another voltage rail. The respective electrodes are interleaved to give d region of overlap or apodization within which the SAW is generated or received, the width of the apodized area varying along the length of the IDT. To prevent performance degradation in the event of an open circuit in a non-overlap region, the electrodes associated with a particular voltage rail are additionally linked by a thin conductor positioned near the boundaries between the apodized or overlap region and each of the non-overlap regions.

Title: Submicron bipolar transistor with buried silicide region
Inventor: FEYGENSON ANATOLY
IPC: H01L21/331
Filed: 1987-05-26
Granted: 1991-01-22
Abstract: Abstract of the Disclosure A high performance bipolar transistor structure is disclosed which exhibits an extremely low extrinsic base resistance by virtue of a silicide layer which is included in the base contact portion of the structure. The silicide layer is situated to be electrically in parallel with the conventional heavily-doped polysilicon base contact region, where a vertical polysilicon runner is used to provide a self-aligned electrical contact to the base.  The parallel combination of the low resistivity (0.5-4 ohm/square) silicide with the polysilicon (sheet resistance of 10- 100 ohm/square) results in a low extrinsic base resistance on the order of 0.5-4 ohm/square.  The disclosed device also includes a sub-micron emitter size, defined by vertical oxide sidewalls above the base region, which further improves the high frequency performance of the device.
