METHODS OF FORMING SEMICONDUCTOR STRUCTURES

A method of forming a semiconductor structure includes forming a first material over a base material by vapor phase epitaxy. The first material has a crystalline portion and an amorphous portion. The amorphous portion of the first material is removed by abrasive planarization. At least a second mate...

Beschreibung
Zusammenfassung:	A method of forming a semiconductor structure includes forming a first material over a base material by vapor phase epitaxy. The first material has a crystalline portion and an amorphous portion. The amorphous portion of the first material is removed by abrasive planarization. At least a second material is formed by vapor phase epitaxy over the crystalline portion of first material. The second material has a crystalline portion and an amorphous portion. The amorphous portion of the second material is removed by abrasive planarization. A semiconductor structure formed by such a method includes the substrate, the first material, the second material, and optionally, an oxide material between the first material and the second material. The substrate, the first material, and the second material define a continuous crystalline structure. Semiconductor structures, memory devices, and systems are also disclosed.
