    摘要: A composite target used in alignment of layers (22-26) on a wafer uses alignment marks placed in a target area (9, 10). First alignment marks (11) are composed of material from a first layer (22) placed on the wafer. As subsequent layers (22-26) are placed on the wafer, alignment marks composed of material from the subsequent layers (23-26) are placed within the target area (9, 10). For example, alignment marks (12) composed of material from a second layer (23) are each placed adjacent to one of the alignment marks composed of material from the first layer (22). Alignment marks (13) composed of material from a third layer (24) are each placed adjacent to one of the alignment marks composed of material from the second layer (23). Alignment marks (14) composed of material from a fourth layer (25) are each placed adjacent to the alignment marks composed of material from the third layer (24). And so on. The alignment marks (11-15) are, for example, each rectangular in shape.

    摘要: A DMOS transistor having a trenched gate is formed in a substrate such that the P body region of the transistor may be formed heavier or deeper while still maintaining a "short" channel. This is accomplished by forming a portion of the N+ type source region within the P body region prior to forming the trench, followed by a second implantation and diffusion of a relatively shallow extension of the N+ source region formed overlying a part of the P body region. The increased depth or doping concentration of the P body region advantageously lowers the resistance of the P body region, while the short channel lowers the on-resistance of the transistor for improved performance.

    摘要: A primary object of the present invention is to manufacture a semiconductor device which has both a high performance and a high degree of integration. The method according to this invention comprises the steps of forming a semiconductor layer (30), (31), (31') provided with recesses in its surface, forming a nitride layer (35) within the recesses, forming an oxide layer (39) over the surface of the semiconductor layer (30) using the nitride layer (35) as a mask, removing the nitride layer (35), and introducing an impurity into the semiconductor layers (31), (31') using the oxide layer (39) as a mask. This method makes it possible to form smaller elements, and is most suitable for the manufacture of an IC device which has both a high performance and a high degree of integration.
