Title: Photoelectric integrated element
Inventor: OKUBO NORIO
IPC: H01L27/14
Filed: 1995-03-23
Abstract: PURPOSE: To obtain a high speed, high sensitivity photoelectric integrated element in which the collector breakdown voltage is enhanced by growing an epitaxial layer, which serves as a collector layer in an HBT region and as a light absorption layer in a PD region, on a semiconductor substrate through a multilevel semiconductor layer. CONSTITUTION: An epitaxial layer, which serves as a collector layer 4a in a heterojunction bipolar transistor region through a multilevel semiconductor layer serving as a collector layer 3a in a heterojunction bipolar transistor region while as a reflection layer 3b in a photodiode region and serves as a light absorption layer 4b in a photodiode region, is grown on a semiconductor substrate. Consequently, a high sensitivity PD can be obtained. Furthermore, collector breakdown voltage can be enhanced by setting the energy band gap of the multilevel semiconductor layer higher than that of the epitaxial layer serving as the collector layer.

Abstract: PURPOSE:To cut down the consumption of cleaning solution by a method wherein the bottom part inner surface of a cleaning vessel liquid-cleaning almost vertically held disc type substrates has almost semicylindrical shape. CONSTITUTION:Within a cleaning vessel made of junctioned quartz glass plate, the lower half part (bottom part side) has the semicylindrical shape fitting to the curvature of the substrate 1 to be cleaned up while the upper half part has the square shape with its surface opened. On the other hand, plural liquid feeding ports 11a are provided on the bottom part to feed cleaning solution. Next, the cleaning vessel 11 is filled up with the cleaning solution fed from the liquid feeding ports 11a; the solution is further fed until it overflows out of the upper part opening; in such a state, plural tube substrates held in a holder 12 are immersed in the cleaning vessel 11. Accordingly, the fine particles and pollutants adhering to the substrates 1 are gradually removed out of the vessel 11 together with the overflowing cleaning solution. Through these procedures, the feeding flow rate of the cleaning solution can be throttled so that the consumption of cleaning solution may be cut down when the overflowed cleaning solution is not reused by circulation.
