Title: Producing method for semiconductor memory device
Inventor: SHONO TOMOFUMI
IPC: H01L21/3205
Filed: 2001-02-26
Abstract: PROBLEM TO BE SOLVED: To easily perform production for providing the large capacity and high integration degree of a capacitive storage part concerning a semiconductor memory device having the capacitive storage part. SOLUTION: Upper layer wiring 16 is formed above a switching transistor provided on one part of a wafer 1. Further, a capacitive storage part 23 is formed above this upper layer wiring 16, and a capacitive storage part contact 18 is formed through the upper layer wiring 16. Thus, in the simultaneous patterning of upper layer wiring to a memory cell part and a peripheral circuit part, while keeping the capacity of a capacitive storage part 18 large, the degree of focus margin is kept great. Since the capacitive storage part contact 18 is made through a bit line 12, a drain 3 and a source 4 can be located symmetrically to a work line 6 similarly to the configuration of installation on the bit line and since a useless space is eliminated, the integration degree is further improved.

Title: Method for manufacturing silicon carbide semiconductor device
Inventor: KATO NOBUYUKI
IPC: H01L21/306
Filed: 2001-03-12
Abstract: PROBLEM TO BE SOLVED: To control a thickness of an SiC layer by enabling a detection of a flattened position of the SiC layer when the SiC layer is flattened. SOLUTION: A method for manufacturing a silicon carbide semiconductor device comprises the steps of forming a trench 2 for forming an impurity layer on an SiC substrate, and forming a sufficiently shallow marker 3 as compared with the trench 2. Then, a depth difference between the trench 2 and the marker 3 are matched with a thickness necessary as the impurity layer. The method further comprises the steps of epitaxially growing the SiC layer 4 so as to embed the trench 2 and the marker 3, then sequentially removing the SiC layer from its surface layer, and advancing flattening until the surface of the substrate 1 is exposed. Since the substrate 1 and the layer 4 are then both transparent or translucent, a profile of the marker 3 can be always observed from a time point of starting the flattening.  When the planarization is advanced and the marker 3 is vanished, its vanishment can be confirmed, and hence flattening is stopped at the confirming time point.
